Suggested Release

Suggested Release: Version 7.2.5.x

Suggested Releases for Older Appliances

If an appliance is too old to run the suggested release and you do not plan to refresh the hardware right now, choose a major version then patch as far as possible. Some major versions are designated long-term or extra long-term, so consider one of those. For an explanation of these terms, see Cisco NGFW Product Line Software Release and Sustaining Bulletin.

If you are interested in a hardware refresh, contact your Cisco representative or partner contact.

Sharing Data with Cisco

The following features share data with Cisco.

Cisco Success Network

Cisco Success Network sends usage information and statistics to Cisco, which are essential to provide you with technical support.

During initial setup and upgrades, you may be asked to enroll. You can also change your enrollment at any time.

Web Analytics

Web analytics provides non-personally-identifiable usage data to Cisco, including but not limited to page interactions, browser versions, product versions, user location, and management IP addresses or hostnames of your FMCs.

You are enrolled by default but you can change your enrollment at any time after you complete initial setup. Note that ad blockers can block web analytics, so if you choose to remain enrolled, please disable ad blocking for the hostnames/IP addresses of your Cisco appliances.

Firepower Classic: Firepower 7000/8000, ASA FirePOWER, NGIPSv

Firepower Classic devices run NGIPS software on the following platforms:

- Firepower 7000/8000 series hardware comes in a range of throughputs, scalability capabilities, and form factors.

- ASA devices can run NGIPS software as a separate application (the ASA FirePOWER module). Traffic is sent to the module after ASA firewall policies are applied. Although there is wide compatibility between ASA and ASA FirePOWER versions, upgrading allows you to take advantage of new features and resolved issues.

- NGIPSv runs the software in virtualized environments.

Device Management

Depending on device model and version, we support the following management methods.

FMC

All devices support remote management with FMC, which must run the same or newer version as its managed devices. This means:

- You can manage older devices with a newer FMC, usually a few major versions back. However, we recommend you always update your entire deployment. New features and resolved issues often require the latest release on both the FMC and its managed devices.

- You cannot upgrade a device past the FMC. Even for maintenance (third-digit) releases, you must upgrade the FMC first.

Note that in most cases you can upgrade an older device directly to the FMC's major version. However, sometimes you can manage an older device that you cannot directly upgrade, even though the target version is supported on the device. For release-specific requirements, see Minimum Version to Upgrade.

5.3.0 for Firepower 7000/8000 series and legacy devices.

FDM

You can use FDM to locally manage a single FTD device.

ASDM

You can use ASDM to locally manage a single ASA FirePOWER module, which is a separate application on an ASA device. Traffic is sent to the module after ASA firewall policies are applied. Newer versions of ASDM can manage newer ASA FirePOWER modules.

Browser Requirements

Browsers

We test with the latest versions of these popular browsers, running on currently supported versions of macOS and Microsoft Windows:

- Google Chrome

- Mozilla Firefox

- Microsoft Internet Explorer 10 and 11 (Windows only)

If you encounter issues with any other browser, or are running an operating system that has reached end of life, we ask that you switch or upgrade. If you continue to encounter issues, contact Cisco TAC.

Note

We do not perform extensive testing with Apple Safari or Microsoft Edge. However, Cisco TAC welcomes feedback on issues you encounter.

Browser Settings and Extensions

Regardless of browser, you must make sure JavaScript, cookies, and TLS v1.2 remain enabled.

If you are using Microsoft Internet Explorer 10 or 11:

- For the Check for newer versions of stored pages browsing history option, choose Automatically.

- Disable the Include local directory path when uploading files to server custom security setting (Internet Explorer 11 only).

- Enable Compatibility View for the appliance IP address/URL.

Note that some browser extensions can prevent you from saving values in fields like the certificate and key in PKI objects. These extensions include, but are not limited to, Grammarly and Whatfix Editor. This happens because these extensions insert characters (such as HTML) in the fields, which causes the system to see them invalid. We recommend you disable these extensions while you’re logged into our products.

Securing Communications

When you first log in, the system uses a self-signed digital certificate to secure web communications. Your browser should display an untrusted authority warning, but also should allow you to add the certificate to the trust store. Although this will allow you to continue, we do recommend that you replace the self-signed certificate with a certificate signed by a globally known or internally trusted certificate authority (CA).

To begin replacing the self-signed certificate:

- FMC or 7000/8000 series: Choose System () > Configuration > HTTPS Certificate.

- FDM: Click Device, then the System Settings > Management Access link, then the Management Web Server tab.

For detailed procedures, see the online help or the configuration guide for your product.

Note

If you do not replace the self-signed certificate:

- Google Chrome does not cache static content, such as images, CSS, or JavaScript. Especially in low bandwidth environments, this can extend page load times.

- Mozilla Firefox can stop trusting the self-signed certificate when the browser updates. If this happens, you can refresh Firefox, keeping in mind that you will lose some settings; see Mozilla's Refresh Firefox support page.

Browsing from a Monitored Network

Many browsers use Transport Layer Security (TLS) v1.3 by default. If you are using an SSL policy to handle encrypted traffic, and people in your monitored network use browsers with TLS v1.3 enabled, websites that support TLS v1.3 fail to load. As a workaround, configure your managed device to remove extension 43 (TLS 1.3) from ClientHello negotiation. In Version 6.2.3.7+, a new CLI command allows you to specify when to downgrade; see New Features.

For more information, see the software advisory titled: Failures loading websites using TLS 1.3 with SSL inspection enabled.

Chapter 3. Features

This document describes new and deprecated features for Version 6.2.3, including upgrade impact.

Upgrade Impact

A feature has upgrade impact if upgrading and deploying can cause the system to process traffic or otherwise act differently without any other action on your part.

Upgrade impact is especially common with new threat detection and application identification capabilities. Or, sometimes the upgrade process has a special requirement; for example, if you must perform a specific task before or after upgrade (change configurations, apply health policies, redo FlexConfigs, and so on).

Upgrade impact can depend on your current platforms, version, and configurations. Note that sometimes a release reintroduces features, enhancements, and critical fixes that were included in some (but not all) previous releases. In that case, upgrade impact depends on whether you are upgrading from a supported/fixed version or from a version without the feature or fix.

Important

The feature descriptions (and upgrade impact) below are for the current major version. For upgrade impact from earlier releases, see Upgrade Guidelines.

Upgrading Snort

If you are still using the Snort 2 inspection engine with threat defense, switch to Snort 3 now.

Snort 3 provides improved detection and performance. It is available starting in threat defense Version 6.7+ (with device manager) and Version 7.0+ (with management center). Snort 2 will be deprecated in a future release. You will eventually be unable to upgrade Snort 2 devices.

In management center deployments, upgrading to threat defense Version 7.2+ also upgrades eligible Snort 2 devices to Snort 3. For devices that are ineligible because they use custom intrusion or network analysis policies, manually upgrade to Snort 3. See Migrate from Snort 2 to Snort 3 in the Firepower Management Center Snort 3 Configuration Guide.

For device manager, manually upgrade Snort. See Intrusion Policies in the Cisco Firepower Threat Defense Configuration Guide for Firepower Device Manager.

New Intrusion Rules and Keywords

Upgrades can import and auto-enable intrusion rules.

Intrusion rule updates (SRUs/LSPs) provide new and updated intrusion rules and preprocessor rules, modified states for existing rules, and modified default intrusion policy settings. If a newer intrusion rule uses keywords that are not supported in your current version, that rule is not imported when you update the SRU/LSP. After you upgrade and those keywords become supported, the new intrusion rules are imported and, depending on your IPS configuration, can become auto-enabled and thus start generating events and affecting traffic flow.

The Snort release notes contain details on new keywords: https://www.snort.org/downloads.

Deprecated FlexConfig Commands

Upgrades can add web interface or Smart CLI support for features that previously required FlexConfig.

The upgrade does not convert FlexConfigs. After upgrade, configure the newly supported features in the web interface or Smart CLI. When you are satisfied with the new configuration, delete the deprecated FlexConfigs.

Caution

Although you cannot newly assign or create FlexConfig objects using deprecated commands, in most cases existing FlexConfigs continue to work and you can still deploy. However, sometimes, using deprecated commands can cause deployment issues.

The feature descriptions below include deprecated FlexConfigs for the current major version. For a full list of deprecated FlexConfigs, see your configuration guide.

- FMC Features in Version 6.2.3

- New Features in FDM Version 6.2.3

- Intrusion Rules and Keywords

- FlexConfig Commands

FMC Features in Version 6.2.3

Although you can manage older devices with a newer management center, we recommend you always update your entire deployment. New traffic-handling features usually require the latest release on both the management center and device. Features where devices are not obviously involved (cosmetic changes to the web interface, cloud integrations) may only require the latest version on the management center, but that is not guaranteed.

Note

Version 6.6 is the last release to support the Cisco Firepower User Agent software as an identity source. You cannot upgrade an FMC with user agent configurations to Version 6.7+. You should switch to Cisco Identity Services Engine/Passive Identity Connector (ISE/ISE-PIC). This will also allow you to take advantage of features that are not available with the user agent. To convert your license, contact your Cisco representative or partner contact.

For more information, see the End-of-Life and End-of-Support for the Cisco Firepower User Agent announcement and the Firepower User Identity: Migrating from User Agent to Identity Services Engine TechNote.

New Features

New Features in FMC Version 6.2.3 Patches

Feature

Details

Version 6.2.3.13

Detection of rule conflicts in FTD NAT policies

After you upgrade to Version 6.2.3.13+, you can no longer create FTD NAT policies with conflicting rules (often referred to as duplicate or overlapping rules). This fixes an issue where conflicting NAT rules were applied out-of-order.

If you currently have conflicting NAT rules, you will be able to deploy post-upgrade. However, your NAT rules will continue to be applied out-of-order.

Therefore, we recommend that after the upgrade, you inspect your FTD NAT policies by editing (no changes are needed) then attempting to resave. If you have rule conflicts, the system will prevent you from saving. Correct the issues, save, and then deploy.

Note

Upgrading to Version 6.3.0 or 6.4.0 deprecates this fix. The issue is addressed in Version 6.3.0.4 and 6.4.0.2.

Supported platforms: FTD

Version 6.2.3.8

EMS extension support

Both the Decrypt-Resign and Decrypt-Known Key SSL policy actions now support the EMS extension during ClientHello negotiation, enabling more secure communications. The EMS extension is defined by RFC 7627.

Note

Version 6.2.3.8 was removed from the Cisco Support & Download site on 2019-01-07. Upgrading to Version 6.2.3.9 also enables EMS extension support. Version 6.3.0 discontinues EMS extension support. In FMC deployments, this feature depends on the device version. Upgrading the FMC to Version 6.3.0 does not discontinue support, but upgrading the device does. Support is reintroduced in Version 6.3.0.1.

Supported platforms: Any

Version 6.2.3.7

TLS v1.3 downgrade CLI command for FTD

A new CLI command allows you to specify when to downgrade TLS v1.3 connections to TLS v1.2.

Many browsers use TLS v1.3 by default. If you are using an SSL policy to handle encrypted traffic, and people in your monitored network use browsers with TLS v1.3 enabled, websites that support TLS v1.3 fail to load.

For more information, see the system support commands in the Cisco Secure Firewall Threat Defense Command Reference. We recommend you use these commands only after consulting with Cisco TAC.

Supported platforms: FTD

Version 6.2.3.3

Site-to-site VPN with clustering

You can now configure site-to-site VPN with clustering. Site-to-site VPN is a centralized feature; only the control unit supports VPN connections.

Supported platforms: Firepower 4100/9300

New Features in FMC Version 6.2.3

Feature

Details

Platform

FTD on the ISA 3000.

You can now run FTD on the ISA 3000 series.

Note that the ISA 3000 supports the Threat license only. It does not support the URL Filtering or Malware licenses. Thus, you cannot configure features that require the URL Filtering or Malware licenses on an ISA 3000. Special features for the ISA 3000 that were supported with the ASA, such as Hardware Bypass, Alarm ports, and so on, are not supported with FTD in this release.

Support for VMware ESXi 6.5.

You can now deploy FMCv, FTDv, and NGIPSv virtual appliances on VMware vSphere/VMware ESXi 6.5.

Firepower Threat Defense: Encryption and VPN

SSL hardware acceleration for Firepower 4100/9300

Firepower 4100/9300 with FTD now support SSL encryption and decryption acceleration in hardware, greatly improving performance. SSL hardware acceleration is disabled by default for all appliances that support it.

Note

This feature is renamed TLS crypto acceleration in Version 6.4.0+.

Supported platforms: Firepower 4100/9300

Certificate enrollment improvements

Non-blocking work flow for certificate enrollment operation allows certificate enrollment on multiple FTD devices in parallel:

- The administrator can now choose to have the Remote Access VPN Policy wizard enroll certificates for all devices in the policy by checking Enroll the selected certificate object on the target devices check box in the Access & Certificate step. If this is chosen, only deployment needs to be done after the wizard finishes. This is selected by default.

- Administrators no longer have to initiate Remote Access VPN certificate enrollment on devices one at a time. The enrollment process for each device is now independent and can be done in parallel.

- In the event of a PKS12 certificate enrollment failure, the administrator no longer needs to re-upload the PKS12 file again to retry enrollment, since it is now stored in the certificate enrollment object.

Supported platforms: FTD

Firepower Threat Defense: High Availability and Clustering

Automatically rejoin the FTD cluster after an internal failure

Formerly, many internal error conditions caused a cluster unit to be removed from the cluster, and you were required to manually rejoin the cluster after resolving the issue. Now, a unit will attempt to rejoin the cluster automatically at the following intervals: 5 minutes, 10 minutes, and then 20 minutes. Internal failures include: application sync timeout; inconsistent application statuses; and so on.

New/modified command: show cluster info auto-join

Supported platforms: Firepower 4100/9300

FTD High Availability Hardening

Version 6.2.3 introduces the following features for FTD devices in high availability:

- Whenever active or standby FTD devices in a high availability pair restart, the FMC may not display accurate high availability status for either managed device. However, the status may not upgrade on the FMC because the communication between the device and the FMC is not established yet. The Refresh Node Status option on the Devices > Device Management page allows you to refresh the high availability node status to obtain accurate information about the active and standby device in a high availability pair.

- The Devices > Device Management page of the FMC UI has a new Switch Active Peer icon.

- Version 6.2.3 includes a new REST API object, Device High Availability Pair Services, that contains four functions:

- DELETE ftddevicehapairs

- PUT ftddevicehapairs

- POST ftddevicehapairs

- GET ftddevicehapairs

Administration and Troubleshooting

FMC High Availability Messaging

FMC high availability pairs have improved UI messaging. The UI now displays interim status messages while FMC pairs are being established and rephrased UI messaging to be more intuitive.

Supported platforms: FMC

External Authentication added for FTD SSH Access

You can now configure external authentication for SSH access to FTD devices using LDAP or RADIUS.

New/modified screen: Devices > Platform Settings > External Authentication

Supported platforms: FTD

Enhanced Vulnerability Database (VDB) Installation

The FMC now warns you before you install a VDB that installing restarts the Snort process, interrupting traffic inspection and, depending on how the managed device handles traffic, possibly interrupting traffic flow. You can cancel the install until a more convenient time, such as during a maintenance window.

These warnings can appear:

- After you download and manually install a VDB.

- When you create a scheduled task to install the VDB.

- When the VDB installs in the background, such as during a previously scheduled task or as part of a Firepower software upgrade.

Supported platforms: FMC

Upgrade Package Push

You can now copy (or push) an upgrade package from the FMC to a managed device before you run the actual upgrade. This is useful because you can push during times of low bandwidth use, outside of the upgrade maintenance window.

When you push to high availability, clustered, or stacked devices, the system sends the upgrade package to the active/control/primary first, then to the standby/data/secondary.

New/modified screens: System > Updates

Supported platforms: FMC

FTD serviceability

Version 6.2.3 improves the show fail over CLI command. The new keyword, -history, details to help troubleshooting.

- Show fail over history displays failure reason along with its specific details.

- Show fail over history details displays fail over history from the peer unit.

Note

This command includes fail over state changes and the reason for the state change for the peer unit.

Supported platforms: FTD

Device list sorting

On the Devices > Devices Management page, you can use the View by drop-down list to sort and view the device list by any of the following categories: group, license, model, or access control policy. In a multidomain deployment, you can also sort and view by domain, which is the default display category in that deployment. Devices must belong to a leaf domain.

Supported platforms: FMC

Audit log improvements

The audit log now denotes if a policy changed on the FTD Platform Settings Devices > Platform Settings page.

Supported platforms: FMC with FTD

Updated FTD CLI commands

The asa_mgmt_plane and asa_dataplane options for FTD device CLI commands are renamed to management-plane and data-plane respectively.

Supported platforms: FTD

Cisco Success Network

Upgrade impact.

Cisco Success Network sends usage information and statistics to Cisco, which are essential to provide you with technical support.

During initial setup and upgrades, you may be asked to enroll. You can also change your enrollment at any time. For more information, see Sharing Data with Cisco.

Supported platforms: FMC

Web Analytics Tracking

Upgrade impact.

Web analytics provides non-personally-identifiable usage data to Cisco, including but not limited to page interactions, browser versions, product versions, user location, and management IP addresses or hostnames of your FMCs.

Initial setup enrolls you in web analytics tracking by default, but you can change your enrollment at any time after that. Upgrades can also enroll or re-enroll you in web analytics tracking. For more information, see Sharing Data with Cisco.

Supported platforms: FMC

Performance

Snort restarts reduced for FTD devices

In Version 6.2.3, fewer FTD configuration changes restart the Snort process on FTD devices.

The FMC now warns you before you deploy if the configuration deployment restarts the Snort process, interrupting traffic inspection and, depending on how the managed device handles traffic, possibly interrupting traffic flow.

Supported platforms: FTD

Traffic Drop on Policy Apply

Version 6.2.3 adds the configure snort preserve-connection {enable | disable} command to the FTD CLI. This command determines whether to preserve existing connections on routed and transparent interfaces if the Snort process goes down. When disabled, all new or existing connections are dropped when Snort goes down and remain dropped until Snort resume. When enabled, connections that were already allowed remain established, but new connections cannot be established until Snort is again available.

Note that you cannot permanently disable this command on a FTD device managed by FDM; existing connections may drop when the settings revert to default during the next configuration deployment.

Increased memory capacity for lower-end appliances

Versions 6.1.0.7, 6.2.0.5, 6.2.2.2, and 6.2.3 increase the memory capacity for lower-end Firepower appliances. This reduces the number of health alerts.

Faster ISE pxGrid discovery

If an ISE pxGrid deployed in high availability fails or becomes unreachable, the FMC now discovers the new active pxGrid faster.

New result limits in reports.

Upgrade can change report settings.

Version 6.2.3 limits the number of results you can use or include in a report section. For table and detail views, you can include fewer records in a PDF report than in an HTML/CSV report.

For HTML/CSV report sections, the new limits are:

- Bar and pie charts: 100 (top or bottom)

- Table views: 400,000

- Detail views: 1,000

For PDF report sections, the new limits are:

- Bar and pie charts: 100 (top or bottom)

- Table views: 100,000

- Detail views: 500

If, before you upgrade the FMC, a section in a report template specifies a larger number of results than the HTML/CSV maximum, the upgrade process lowers the setting to the new maximum value.

For report templates that generate PDF reports, if you exceed the PDF limit in any template section, the upgrade process changes the output format to HTML. To continue generating PDFs, lower the results limit to the PDF maximum. If you do this after the upgrade, set the output format back to PDF.

Firepower Management Center REST API

FMC REST API Improvements

The new FMC REST APIs support the use of CRUD (create, retrieve, upgrade, and delete) operations for NAT rules, static routing configuration, and corresponding objects while migrating from ASA FirePOWER to FTD.

Newly introduced APIs for NAT:

- NAT rules

- FTD NAT policies

- Auto NAT rules

- Manual NAT rules

When deploying FTD devices in Cisco ACI, APIs enable APIC controller to add proper static routes in place, along with other configuration settings that are needed for a particular service graph. It also enables PBR service graph insertion, which is currently the most flexible way of inserting FTD in ACI.

Newly introduced APIs for Static Route:

- IPv4 static routes

- IPv6 static routes

- SLA monitors

Deprecated Features

Deprecated Features in FMC Version 6.2.3

Feature

Details

Expired CA certificates for dynamic analysis with AMP for Networks.

On June 15, 2018, some Firepower deployments stopped being able to submit files for dynamic analysis. This occurred due to an expired CA certificate that was required for communications with the AMP Threat Grid cloud. Version 6.3 is the first major version with the new certificate.

If you do not want to upgrade to Version 6.3+, you can patch to obtain the new certificate and reenable dynamic analysis, as follows:

- Version 6.2.3 → patch to Version 6.2.3.4

- Version 6.2.2 → patch to Version 6.2.2.4

- Version 6.2.1 → no patches available

- Version 6.2 → patch to Version 6.2.0.6

- Version 6.1 → patch to Version 6.1.0.7

- Version 6.0 → no patches available

You can also apply a hotfix. For available hotfixes, see the Cisco Secure Firewall Threat Defense/Firepower Hotfix Release Notes. Find the hotfix for your version and platform that applies to CSCvj07038: Firepower devices need to trust Threat Grid certificate.

If this is your first time installing the patch or hotfix, make sure your firewall allows outbound connections to fmc.api.threatgrid.com (replacing panacea.threatgrid.com) from both the FMC and its managed devices.

Note that upgrading a patched or hotfixed deployment to either Version 6.2.0 or Version 6.2.3 reverts to the old certificate and you must patch or hotfix again.

Deprecated: Geolocation details.

In May 2022 we split the GeoDB into two packages: a country code package that maps IP addresses to countries/continents, and an IP package that contains additional contextual data associated with routable IP addresses. The contextual data in the IP package can include additional location details, as well as connection information such as ISP, connection type, proxy type, domain name, and so on.

The new country code package has the same file name as the old all-in-one package: Cisco_GEODB_Update-date-build. This allows deployments running Version 7.1 and earlier to continue to obtain GeoDB updates. If you manually download GeoDB updates—for example, in an air-gapped deployment—make sure you get the country code package and not the IP package.

Important

This split does not affect geolocation rules or traffic handling in any way—those rules rely only on the data in the country code package. However, because the country code package essentially replaces the all-in-one package, the contextual data is no longer updated and will grow stale. To obtain fresh data, upgrade or reimage the FMC to Version 7.2+ and update the GeoDB.

New Features in FDM Version 6.2.3

New and Deprecated Features in FDM Version 6.2.3

Feature

Description

SSL/TLS decryption.

You can decrypt SSL/TLS connections so that you can inspect the contents of the connection. Without decryption, encrypted connections cannot be effectively inspected to identify intrusion and malware threats, or to enforce compliance with your URL and application usage polices. We added the Policies > SSL Decryption page and Monitoring > SSL Decryption dashboard.

Attention

Identity policies that implement active authentication automatically generate SSL decryption rules. If you upgrade from a release that does not support SSL decryption, the SSL decryption policy is automatically enabled if you have this type of rule. However, you must specify the certificate to use for Decrypt-Resign rules after completing the upgrade. Please edit the SSL decryption settings immediately after upgrade.

Security Intelligence blocking.

From the new Policies > Security Intelligence page you can configure a Security Intelligence policy, which you can use to drop unwanted traffic based on source/destination IP address or destination URL. Any allowed connections will still be evaluated by access control policies and might eventually be dropped. You must enable the Threat license to use Security Intelligence.

We also renamed the Policies dashboard to Access And SI Rules, and the dashboard now includes Security Intelligence rule-equivalents as well as access rules.

Intrusion rule tuning.

You can change the action for intrusion rules within the pre-defined intrusion policies you apply with your access control rules. You can configure each rule to drop or generate events (alert) matching traffic, or disable the rule. You can change the action for enabled rules only (those set to drop or alert); you cannot enable a rule that is disabled by default. To tune intrusion rules, choose Policies > Intrusion.

Automatic network analysis policy (NAP) assignment based on intrusion policy.

In previous releases, the Balanced Security and Connectivity network analysis policy was always used for preprocessor settings, regardless of the intrusion policy assigned to a specific source/destination security zone and network object combination. Now, the system automatically generates NAP rules to assign the same-named NAP and intrusion policies to traffic based on those criteria. Note that if you use Layer 4 or 7 criteria to assign different intrusion policies to traffic that otherwise matches the same source/destination security zone and network object, you will not get perfectly matching NAP and intrusion policies. You cannot create custom network analysis policies.

Drill-down reports for the Threats, Attackers, and Targets dashboards.

You can now click into the Threats, Attackers, and Targets dashboards to view more detail about the reported items. These dashboards are available on the Monitoring page.

Because of these new reports, you will lose reporting data for these dashboards when upgrading from a pre-6.2.3 release.

Web Applications dashboard.

The new Web Applications dashboard shows the top web applications, such as Google, that are being used in the network. This dashboard augments the Applications dashboard, which provides protocol-oriented information, such as HTTP usage.

New Zones dashboard replaces the Ingress Zone and Egress Zone dashboards.

The new Zones dashboard shows the top security zone pairs for traffic entering and then exiting the device. This dashboard replaces the separate dashboards for Ingress and Egress zones.

New Malware dashboard.

The new Malware dashboard shows the top Malware action and disposition combinations. You can drill down to see information on the associated file types. You must configure file policies on access rules to see this information.

Self-signed internal certificates, and Internal CA certificates.

You can now generate self-signed internal identity certificates. You can also upload or generate self-signed internal CA certificates for use with SSL decryption policies. Configure these features on the Objects > Certificates page.

Ability to edit DHCP server settings when editing interface properties.

You can now edit settings for a DHCP server configured on an interface at the same time you edit the interface properties. This makes it easy to redefine the DHCP address pool if you need to change the interface IP address to a different subnet.

The Cisco Success Network sends usage and statistics data to Cisco to improve the product and provide effective technical support.

You can connect to the Cisco Success Network to send data to Cisco. By enabling Cisco Success Network, you are providing usage information and statistics to Cisco which are essential for Cisco to provide you with technical support. This information also allows Cisco to improve the product and to make you aware of unused available features so that you can maximize the value of the product in your network. You can enable the connection when you register the device with the Cisco Smart Software Manager, or later at your choice. You can disable the connection at any time.

Cisco Success Network is a cloud service. The Device > System Settings > Cloud Management page is renamed Cloud Services. You can configure Cisco Defense Orchestrator from the same page.

FTDv for Kernel-based Virtual Machine (KVM) hypervisor device configuration.

You can configure Firepower Threat Defense on FTDv for KVM devices using FDM. Previously, only VMware was supported.

Note

You must install a new 6.2.3 image to get FDM support. You cannot upgrade an existing virtual machine from an older version and then switch to FDM.

Support for VMware ESXi 6.5.

You can now deploy FTDv on VMware vSphere/VMware ESXi 6.5.

ISA 3000 (Cisco 3000 Series Industrial Security Appliances) device configuration.

You can configure Firepower Threat Defense on ISA 3000 devices using FDM. Note that the ISA 3000 supports the Threat license only. It does not support the URL Filtering or Malware licenses. Thus, you cannot configure features that require the URL Filtering or Malware licenses on an ISA 3000.

Optional deployment on update of the rules database or VDB.

When you update the intrusion rules database or VDB, or configure an update schedule, you can prevent the immediate deployment of the update. Because the update restarts the inspection engines, there is a momentary traffic drop during the deployment. By not deploying automatically, you can choose to initiate the deployment at a time when traffic drops will be least disruptive.

Note

A VDB download can also restart Snort all by itself, and then again cause a restart on deployment. You cannot stop the restart on download.

Improved messages that indicate whether a deployment restarts Snort. Also, a reduced need to restart Snort on deployment.

Before you start a deployment, FDM indicates whether the configuration updates require a Snort restart. Snort restarts result in the momentary dropping of traffic. Thus, you now know whether a deployment will not impact traffic and can be done immediately, or will impact traffic, so that you can deploy at a less disruptive time.

In addition, in prior releases, Snort restarted on every deployment. Now, Snort restarts for the following reasons only:

- you enable or disable SSL decryption policies

- an updated rules database or VDB was downloaded

- you changed the MTU on one or more physical interface (but not subinterface)

CLI console in FDM.

You can now open a CLI Console from FDM. The CLI Console mimics an SSH or console session, but allows a subset of commands only: show , ping , traceroute , and packet-tracer . Use the CLI Console for troubleshooting and device monitoring.

Support for blocking access to the management address.

You can now remove all management access list entries for a protocol to prevent access to the management IP address. Previously, if you removed all entries, the system defaulted to allowing access from all client IP addresses. On upgrade to 6.2.3, if you previously had an empty management access list for a protocol (HTTPS or SSH), the system creates the default allow rule for all IP addresses. You can then delete these rules as needed.

In addition, FDM will recognize changes you make to the management access list from the CLI, including if you disable SSH or HTTPS access.

Ensure that you enable HTTPS access for at least one interface, or you will not be able to configure and manage the device.

EMS extension support.

Both the Decrypt-Resign and Decrypt-Known Key SSL policy actions now support the EMS extension during ClientHello negotiation, enabling more secure communications. The EMS extension is defined by RFC 7627.

Note

Version 6.2.3.8 was removed from the Cisco Support & Download site on 2019-01-07. Upgrading to Version 6.2.3.9 also enables EMS extension support. Version 6.3.0 discontinues EMS extension support. Support is reintroduced in Version 6.3.0.1.

Minimum FTD: Version 6.2.3.8

TLS v1.3 downgrade CLI command for FTD.

A new CLI command allows you to specify when to downgrade TLS v1.3 connections to TLS v1.2.

Many browsers use TLS v1.3 by default. If you are using an SSL policy to handle encrypted traffic, and people in your monitored network use browsers with TLS v1.3 enabled, websites that support TLS v1.3 fail to load.

For more information, see the system support commands in the Cisco Secure Firewall Threat Defense Command Reference. We recommend you use these commands only after consulting with Cisco TAC.

Minimum FTD: Version 6.2.3.7

Smart CLI and FlexConfig for configuring features using the device CLI.

Smart CLI and FlexConfig allows you to configure features that are not yet directly supported through FDM policies and settings. FTD uses ASA configuration commands to implement some features. If you are a knowledgeable and expert user of ASA configuration commands, you can configure these features on the device using the following methods:

- Smart CLI—(Preferred method.) A Smart CLI template is a pre-defined template for a particular feature. All of the commands needed for the feature are provided, and you simply need to select values for variables. The system validates your selection, so that you are more likely to configure a feature correctly. If a Smart CLI template exists for the feature you want, you must use this method. In this release, you can configure OSPFv2 using the Smart CLI.

- FlexConfig—The FlexConfig policy is a collection of FlexConfig objects. The FlexConfig objects are more free-form than Smart CLI templates, and the system does no CLI, variable, or data validation. You must know ASA configuration commands and follow the ASA configuration guides to create a valid sequence of commands.

Caution

Cisco strongly recommends using Smart CLI and FlexConfig only if you are an advanced user with a strong ASA background and at your own risk. You may configure any commands that are not blacklisted. Enabling features through Smart CLI or FlexConfig may cause unintended results with other configured features.

FTD REST API, and an API Explorer.

You can use a REST API to programmatically interact with a Firepower Threat Defense device that you are managing locally through FDM. There is an API Explorer that you can use to view object models and test the various calls you can make from a client program. To open the API Explorer, log into FDM, and then change the path on the URL to /#/api-explorer, for example, https://ftd.example.com/#/api-explorer.

Intrusion Rules and Keywords

Upgrades can import and auto-enable intrusion rules.

Intrusion rule updates (SRUs/LSPs) provide new and updated intrusion rules and preprocessor rules, modified states for existing rules, and modified default intrusion policy settings. If a newer intrusion rule uses keywords that are not supported in your current version, that rule is not imported when you update the SRU/LSP.

After you upgrade and those keywords become supported, the new intrusion rules are imported and, depending on your IPS configuration, can become auto-enabled and thus start generating events and affecting traffic flow.

You can find your Snort version in the Bundled Components section of the compatibility guide, or use one of these commands:

- FMC: Choose Help > About.

- FDM: Use the show summary CLI command.

The Snort release notes contain details on new keywords. You can read the release notes on the Snort download page: https://www.snort.org/downloads.

FlexConfig Commands

This document lists deprecated FlexConfig objects and commands along with the other deprecated features for this release. For a full list of prohibited commands, including those prohibited when FlexConfig was introduced and those deprecated in previous releases, see your configuration guide.

Caution

In most cases, your existing FlexConfig configurations continue to work post-upgrade and you can still deploy. However, in some cases, using deprecated commands can cause deployment issues.

About FlexConfig

Some FTD features are configured using ASA configuration commands. You can use Smart CLI or FlexConfig to manually configure various ASA features that are not otherwise supported in the web interface.

Upgrades can add GUI or Smart CLI support for features that you previously configured using FlexConfig. This can deprecate FlexConfig commands that you are currently using; your configurations are not automatically converted. After the upgrade, you cannot assign or create FlexConfig objects using the newly deprecated commands.

After the upgrade, examine your FlexConfig policies and objects. If any contain commands that are now deprecated, messages indicate the problem. We recommend you redo your configuration. When you are satisfied with the new configuration, you can delete the problematic FlexConfig objects or commands.

Deployments: Firepower Threat Defense

Upgrading from: Version 6.2.3 through 6.2.3.9

Directly to: Version 6.2.3.10 only

Known issue: CSCvo39052

Upgrading an FTD device to Version 6.2.3.10 with CC mode enabled causes a FSIC (file system integrity check) failure when the device reboots.

Caution

If security certifications compliance is enabled and the FSIC fails, the software does not start, remote SSH access is disabled, and you can access the appliance only via local console. If this happens, contact Cisco TAC.

If your FTD deployment requires security certifications compliance (CC mode), we recommend you upgrade directly to Version 6.2.3.13+. For Firepower 4100/9300 devices, we also recommend that you upgrade to FXOS 2.3.1.130+.

Version 6.2.3.3 FTD Device Cannot Switch to Local Management

Deployments: FTD wth FMC

Upgrading from: Version 6.2.3 through Version 6.2.3.2

Directly to: Version 6.2.3.3 only

In Version 6.2.3.3, you cannot switch Firepower Threat Defense device management from FMC to FDM. This happens even if you uninstall the Version 6.2.3.3 patch. If you want to switch to local management at that point, either freshly install Version 6.2.3, or contact Cisco TAC.

As a workaround, switch management before you upgrade to Version 6.2.3.3. Or, upgrade to the latest patch. Keep in mind that you lose device configurations when you switch management.

Note that you can switch management from FDM to FMC in Version 6.2.3.3.

Hotfix Before Upgrading Version 6.2.3-88 FMCs

Deployments: FMC

Upgrading from: Version 6.2.3-88

Directly to: Version 6.2.3.1, Version 6.2.3.2, or Version 6.2.3.3

Sometimes Cisco releases updated builds of Firepower upgrade packages. Version 6.2.3-88 has been replaced by a later build. If you upgrade an FMC running Version 6.2.3-88 to Version 6.2.3.1, Version 6.2.3.2, or Version 6.2.3.3, the SSE cloud connection continuously drops and generates errors. Uninstalling the patch does not resolve the issue.

If you are running Version 6.2.3-88, install Hotfix T before you upgrade.

Remove Site IDs from Version 6.1.x Firepower Threat Defense Clusters Before Upgrade

Deployments: Firepower Threat Defense clusters

Upgrading from: Version 6.1.x

Directly to: Version 6.2.3 through 6.4.0

Firepower Threat Defense Version 6.1.x clusters do not support inter-site clustering (you can configure inter-site features using FlexConfig starting in Version 6.2.0).

If you deployed or redeployed a Version 6.1.x cluster in FXOS 2.1.1, and you entered a value for the (unsupported) site ID, remove the site ID (set to 0) on each unit in FXOS before you upgrade. Otherwise, the units cannot rejoin the cluster after the upgrade.

If you already upgraded, remove the site ID from each unit, then reestablish the cluster. To view or change the site ID, see the Cisco FXOS CLI Configuration Guide.

Upgrade Can Unregister FDM from CSSM

Deployments: FTD with FDM

Upgrading from: Version 6.2 through 6.2.2.x

Directly to: Version 6.2.3 through 6.4.0

Note

Upgrades from 6.2.3 and 6.2.3.1 directly to 6.2.3.2 through 6.2.3.5 are also affected.

Upgrading FTD with FDM may unregister the device from the Cisco Smart Software Manager. After the upgrade completes, check your license status.

Procedure

Step 1

Click Device, then click View Configuration in the Smart License summary.

Step 2

If the device is not registered, click Register Device.

Upgrade Failure: Firepower 2100 Series from Version 6.2.2.5

Deployments: Firepower 2100 series with FTD, managed by FDM

Upgrading from: Version 6.2.2.5

Directly to: Version 6.2.3 only

If you change the DNS settings on a Firepower 2100 series device running Version 6.2.2.5, and then upgrade to Version 6.2.3 without an intermediate deployment, the upgrade fails. You must deploy or execute an action that triggers a deployment, such as an SRU update, before you upgrade the device.

Edit/Resave Realms After FTD/FDM Upgrade

Upgrading from: Version 6.1 through 6.2.2.x

Directly to: Version 6.2.3 only

If you configured network or port objects that are used only in intrusion policy variable sets, deploying associated access control policies after the upgrade fails. If this happens, edit the access control policy, make a change (such as editing the description), save, and redeploy.

Upgrade Failure: FDM on ASA 5500-X Series from Version 6.2.0

Deployments: FTD with FDM, running on a lower-memory ASA 5500-X series device

Upgrading from: Version 6.2.0

Directly to: Version 6.2.2 through 6.4.0

If you are upgrading from Version 6.2.0, the upgrade may fail with an error of: Uploaded file is not a valid system upgrade file. This can occur even if you are using the correct file.

If this happens, you can try the following workarounds:

- Try again.

- Use the CLI to upgrade.

- Upgrade to 6.2.0.1 first.

Access Control Can Get Latency-Based Performance Settings from SRUs

Deployments: FMC

Upgrading from: 6.1.x

Directly to: 6.2.0+

New access control policies in Version 6.2.0+ by default get their latency-based performance settings from the latest intrusion rule update (SRU). This behavior is controlled by a new Apply Settings From option. To configure this option, edit or create an access control policy, click Advanced, and edit the Latency-Based Performance Settings.

When you upgrade to Version 6.2.0+, the new option is set according to your current (Version 6.1.x) configuration. If your current settings are:

- Default: The new option is set to Installed Rule Update. When you deploy after the upgrade, the system uses the latency-based performance settings from the latest SRU. It is possible that traffic handling could change, depending on what the latest SRU specifies.

- Custom: The new option is set to Custom. The system retains its current performance settings. There should be no behavior change due to this option.

We recommend you review your configurations before you upgrade. From the Version 6.1.x FMC web interface, view your policies' Latency-Based Performance Settings as described earlier, and see whether the Revert to Defaults button is dimmed. If the button is dimmed, you are using the default settings. If it is active, you have configured custom settings.

'Snort Fail Open' Replaces 'Failsafe' on FTD

Deployments: FTD with FMC

Upgrading from: Version 6.1.x

Directly to: Version 6.2+

In Version 6.2, the Snort Fail Open configuration replaces the Failsafe option on FMC-managed Firepower Threat Defense devices. While Failsafe allows you to drop traffic when Snort is busy, traffic automatically passes without inspection when Snort is down. Snort Fail Open allows you to drop this traffic.

When you upgrade an FTD device, its new Snort Fail Open setting depends on its old Failsafe setting, as follows. Although the new configuration should not change traffic handling, we still recommend that you consider whether to enable or disable Failsafe before you upgrade.

Migrating Failsafe to Snort Fail Open

Version 6.1 Failsafe

Version 6.2 Snort Fail Open

Behavior

Disabled (default behavior)

Busy: Disabled

Down: Enabled

New and existing connections drop when the Snort process is busy and pass without inspection when the Snort process is down.

Enabled

Busy: Enabled

Down: Enabled

New and existing connections pass without inspection when the Snort process is busy or down.

Note that Snort Fail Open requires Version 6.2 on the device. If you are managing a Version 6.1.x device, the FMC web interface displays the Failsafe option.

Upgrade Guidelines for the Firepower 4100/9300 Chassis

For the Firepower 4100/9300, major FTD upgrades also require a chassis upgrade (FXOS and firmware). Maintenance release and patches rarely require this, but you may still want to upgrade to the latest build to take advantage of resolved issues.

Upgrade Guidelines for the Firepower 4100/9300 Chassis

Guideline

Details

FXOS upgrades.

FXOS 2.3.1.73+ is required to run threat defense Version 6.2.3 on the Firepower 4100/9300.

Note

Firepower 6.2.3.16+ requires FXOS 2.3.1.157+.

You can upgrade to any later FXOS version from as far back as FXOS 2.2.2. For critical and release-specific upgrade guidelines, new and deprecated features, and open and resolved bugs, see the Cisco Firepower 4100/9300 FXOS Release Notes.

Firmware upgrades.

FXOS 2.14.1+ upgrades include firmware. If you are upgrading to an earlier FXOS version, see the Cisco Firepower 4100/9300 FXOS Firmware Upgrade Guide.

Time to upgrade.

Chassis upgrade can take up to 45 minutes and can affect traffic flow and inspection. For more information, see Traffic Flow and Inspection for Chassis Upgrades.

Unresponsive Upgrades

Do not make or deploy configuration changes during upgrade. Even if the system appears inactive, do not manually reboot or shut down during upgrade. You could place the system in an unusable state and require a reimage. If you encounter issues with the upgrade, including a failed upgrade or unresponsive appliance, contact Cisco TAC.

Uninstall a Patch

In FMC and ASDM deployments, you can uninstall most patches. If you need to return to an earlier major release, you must reimage. For guidelines, limitations, and procedures, see Uninstall a Patch in the FMC upgrade guide or Uninstall ASA FirePOWER Patches with ASDM in these release notes.

- [6.2.3–6.5, because 6.6+ patches all uninstall] Patches That Support Uninstall

- Uninstall ASA FirePOWER Patches with ASDM

Uninstall ASA FirePOWER Patches with ASDM

Use the Linux shell (expert mode) to uninstall device patches. You must have access to the device shell as the admin user for the device, or as another local user with CLI configuration access. If you disabled shell access, contact Cisco TAC to reverse the lockdown.

For ASA failover pairs and clusters, minimize disruption by uninstalling from one appliance at a time. Wait until the patch has fully uninstalled from one unit before you move on to the next.

Uninstall Order for ASA with FirePOWER Services in ASA Failover Pairs/Clusters

Configuration

Uninstall Order

ASA active/standby failover pair, with ASA FirePOWER

Always uninstall from the standby.

1. Uninstall from the ASA FirePOWER module on the standby ASA device.

2. Fail over.

3. Uninstall from the ASA FirePOWER module on the new standby ASA device.

ASA active/active failover pair, with ASA FirePOWER

Make both failover groups active on the unit you are not uninstalling.

1. Make both failover groups active on the primary ASA device.

2. Uninstall from the ASA FirePOWER module on the secondary ASA device.

3. Make both failover groups active on the secondary ASA device.

4. Uninstall from the ASA FirePOWER module on the primary ASA device.

ASA cluster, with ASA FirePOWER

Disable clustering on each unit before you uninstall. Uninstall from one unit at a time, leaving the control unit for last.

1. On a data unit, disable clustering.

2. Uninstall from the ASA FirePOWER module on that unit.

3. Reenable clustering. Wait for the unit to rejoin the cluster.

4. Repeat for each data unit.

5. On the control unit, disable clustering. Wait for a new control unit to take over.

6. Uninstall from the ASA FirePOWER module on the former control unit.

7. Reenable clustering.

Caution

Do not make or deploy configuration changes during uninstall. Even if the system appears inactive, do not manually reboot, shut down, or restart an uninstall in progress. You could place the system in an unusable state and require a reimage. If you encounter issues with the uninstall, including a failed uninstall or unresponsive appliance, contact Cisco TAC.

Before you begin

- In ASA failover/cluster deployments, make sure you are uninstalling from the correct device.

- Make sure your deployment is healthy and successfully communicating.

Procedure

Step 1

If the device's configurations are out of date, deploy now from ASDM.

Deploying before you uninstall reduces the chance of failure. Make sure the deployment and other essential tasks are completed. Tasks running when the uninstall begins are stopped, become failed tasks, and cannot be resumed. You can manually delete failed status messages later.

Step 2

Access the Firepower CLI on the ASA FirePOWER module. Log in as admin or another Firepower CLI user with configuration access.

You can either SSH to the module's management interface (hostname or IP address) or use the console. Note that the console port defaults to the ASA CLI and you must use the session sfr command to access the Firepower CLI.

Step 3

Use the expert command to access the Linux shell.

Step 4

Verify the uninstall package is in the upgrade directory.

ls /var/sf/updates

Patch uninstallers are named like upgrade packages, but have Patch_Uninstaller instead of Patch in the file name. When you patch a device, the uninstaller for that patch is automatically created in the upgrade directory. If the uninstaller is not there, contact Cisco TAC.

Step 5

Run the uninstall command, entering your password when prompted.

sudo install_update.pl --detach /var/sf/updates/uninstaller_name

Caution

The system does not ask you to confirm. Entering this command starts the uninstall, which includes a device reboot. Interruptions in traffic flow and inspection during an uninstall are the same as the interruptions that occur during an upgrade. Make sure you are ready. Note that using the --detach option ensures the uninstall process is not killed if your SSH session times out, which can leave the device in an unstable state.

Step 6

Monitor the uninstall until you are logged out.

For a detached uninstall, use tail or tailf to display logs:
tail /ngfw/var/log/sf/update.status

Otherwise, monitor progress in the console or terminal.

Step 7

Verify uninstall success.

After the uninstall completes, confirm that the module has the correct software version. Choose Configuration > ASA FirePOWER Configurations > Device Management > Device.

Step 8

Redeploy configurations.

What to do next

In ASA failover/cluster deployments, repeat this procedure for each unit in your planned sequence.

Traffic Flow and Inspection

Device upgrades (software and operating system) affect traffic flow and inspection. Schedule maintenance windows when this will have the least impact.

Traffic Flow and Inspection for Chassis Upgrades

Upgrading FXOS reboots the chassis. For FXOS upgrades to Version 2.14.1+ that include firmware upgrades, the device reboots twice—once for FXOS and once for the firmware.

Even in high availability/clustered deployments, you upgrade FXOS on each chassis independently. To minimize disruption, upgrade one chassis at a time.

Software Upgrades for Standalone Devices

Devices operate in maintenance mode while they upgrade. Entering maintenance mode at the beginning of the upgrade causes a 2-3 second interruption in traffic inspection. Interface configurations determine how a standalone device handles traffic both then and during the upgrade.

Switched interfaces are also known as bridge group or transparent interfaces.

Uninterrupted, not inspected.

Software Upgrades for High Availability/Scalability

You should not experience interruptions in traffic flow or inspection while upgrading high availability or clustered devices. For high availability pairs, the standby device upgrades first. The devices switch roles, then the new standby upgrades.

For clusters, the data security module or modules upgrade first, then the control module. During the control security module upgrade, although traffic inspection and handling continues normally, the system stops logging events. Events for traffic processed during the logging downtime appear with out-of-sync timestamps after the upgrade is completed. However, if the logging downtime is significant, the system may prune the oldest events before they can be logged.

Note

Upgrading an inter-chassis cluster from Version 6.2.0, 6.2.0.1, or 6.2.0.2 causes a 2-3 second traffic interruption in traffic inspection when each module is removed from the cluster. Upgrading high availability or clustered devices from Version 6.0.1 through 6.2.2.x may have additional upgrade path requirements; see the upgrade path information in the planning chapter of the Cisco Firepower Management Center Upgrade Guide, Version 6.0–7.0.

Software Uninstall (Patches)

For standalone devices, interruptions to traffic flow and inspection during patch uninstall are the same as for upgrade. In high availability/scalability deployments, you must explicitly plan an uninstall order that minimizes disruption. This is because you uninstall patches from devices individually, even those that you upgraded as a unit.

Deploying Configuration Changes

Restarting the Snort process briefly interrupts traffic flow and inspection on all devices, including those configured for high availability/scalability. Interface configurations determine whether traffic drops or passes without inspection during the interruption. When you deploy without restarting Snort, resource demands may result in a small number of packets dropping without inspection.

Snort typically restarts during the first deployment immediately after the upgrade. It does not restart during other deployments unless, before deploying, you modify specific policy or device configurations.

Time and Disk Space Tests

For reference purposes, we provide reports of in-house time and disk space tests for FMC and device software upgrades.

Time Tests

We report the slowest tested time of all software upgrades tested on a particular platform/series. Your upgrade will likely take longer than the provided times for multiple reasons, as explained in the following table. We recommend you track and record your own upgrade times so you can use them as future benchmarks.

Caution

Do not make or deploy configuration changes during upgrade. Even if the system appears inactive, do not manually reboot, shut down, or restart an upgrade in progress. You could place the system in an unusable state and require a reimage. If you encounter issues with the upgrade, including a failed upgrade or unresponsive appliance, contact Cisco TAC.

Time Test Conditions for Software Upgrades

Condition

Details

Deployment

Times for device upgrades are from tests in a FMC deployments. Raw upgrade times for remotely and locally managed devices are similar, given similar conditions.

Versions

For major and maintenance releases, we test upgrades from all eligible previous major versions. For patches, we test upgrades from the base version. Upgrade time usually increases if your upgrade skips versions.

Models

In most cases, we test on the lowest-end models in each series, and sometimes on multiple models in a series.

Virtual appliances

We test with the default settings for memory and resources. However, note that upgrade time in virtual deployments is highly hardware dependent.

High availability/scalability

Unless otherwise noted, we test on standalone devices.

In a high availability or clustered configuration, devices upgrade one at a time to preserve continuity of operations, with each device operating in maintenance mode while it upgrades. Upgrading a device pair or entire cluster, therefore, takes longer than upgrading a standalone device.

Configurations

We test on appliances with minimal configurations and traffic load.

Upgrade time can increase with the complexity of your configurations, size of event databases, and whether/how those things are affected by the upgrade. For example, if you use a lot of access control rules and the upgrade needs to make a backend change to how those rules are stored, the upgrade can take longer.

Components

We report times for the software upgrade itself and the subsequent reboot only. This does not include time for operating system upgrades, transferring upgrade packages, readiness checks, VDB and intrusion rule (SRU/LSP) updates, or deploying configurations.

Disk Space Tests

We report the most disk space used of all software upgrades tested on a particular platform/series. This includes the space needed to copy the upgrade package to the device.

We also report the space needed on the FMC (in either /Volume or /var) for the device upgrade package. If you are using FDM, ignore those values.

When we report disk space estimates for a particular location (for example, /var or /ngfw), we are reporting the disk space estimate for the partition mounted in that location. On some platforms, these locations may be on the same partition.

Without enough free disk space, the upgrade fails.

Chapter 5. Install the Software

If you cannot or do not want to upgrade to Version 6.2.3, you can freshly install major releases. This is also called reimaging. We do not provide installation packages for patches. To run a particular patch, install the appropriate major release, then apply the patch.

- Installation Guidelines

- Installation Guides

Installation Guidelines

These guidelines can prevent common reimage issues, but are not comprehensive. For detailed checklists and procedures, see the appropriate installation guide.

Backups

Before you reimage, we strongly recommend you back up to a secure remote location and verify transfer success. Reimaging returns most settings to factory defaults, including the system password. It deletes any backups left on the appliance.

Note

If you want to reimage so that you don't have to upgrade, due to version restrictions you cannot use a backup to import your old configurations. You must recreate your configurations manually.

Appliance Access

For devices, make sure traffic from your location does not have to traverse the device itself to access the device's management interface. In FMC deployments, you should also able to access the FMC's management interface without traversing the device.

Unregistering from Smart Software Manager

Before you reimage any appliance or switch device management, you may need to unregister from the Cisco Smart Software Manager (CSSM). This is to avoid accruing orphan entitlements, which can prevent you from reregistering.

Unregistering removes an appliance from your virtual account, unregisters it from the cloud and cloud services, and releases associated licenses so they can be can be reassigned. When you unregister an appliance, it enters Enforcement mode. Its current configuration and policies continue to work as-is, but you cannot make or deploy any changes.

If you plan to restore from backup, do not unregister before you reimage and do not remove devices from the FMC. Instead, manually revert any licensing changes made since you took the backup. After the restore completes, reconfigure licensing. If you notice licensing conflicts or orphan entitlements, contact Cisco TAC.

Scenarios for Unregistering from CSSM (Not Restoring from Backup)

Scenario

Action

Reimage the FMC.

Unregister manually.

Model migration for the FMC.

Unregister manually, before you shut down the source FMC.

Reimage FTD with FMC.

Unregister automatically, by removing the device from the FMC.

Reimage FTD with FDM.

Unregister manually.

Switch FTD from FMC to FDM.

Unregister automatically, by removing the device from the FMC.

Switch FTD from device manager to FMC.

Unregister manually.

Removing Devices from the FMC

In FMC deployments, if you plan to manually configure the reimaged appliance, remove devices from the FMC before you reimage either. If you plan to restore from backup, you do not need to do this.

Scenarios for Removing Devices from the FMC (Not Restoring from Backup)

Scenario

Action

Reimage the FMC.

Remove all devices from management.

Reimage FTD.

Remove the one device from management.

Switch FTD from FMC to FDM.

Remove the one device from management.

Fully Reimaging FTD Hardware to Downgrade FXOS

For FTD hardware models that use the FXOS operating system, reimaging to an earlier software version may require a full reimage, regardless of whether FXOS is bundled with the software or upgraded separately.

Scenarios for Full Reimages

Model

Details

Firepower 2100 series

If you use the erase configuration method to reimage, FXOS may not downgrade along with the software. This can cause failures, especially in high availability deployments. We recommend that you perform full reimages of these devices.

Firepower 4100/9300

Reverting FTD does not downgrade FXOS.

For the Firepower 4100/9300, major FTD versions have a specially qualified and recommended companion FXOS version. After you return to the earlier version of FTD, you may be running a non-recommended version of FXOS (too new).

Although newer versions of FXOS are backwards compatible with older FTD versions, we do perform enhanced testing for the recommended combinations. You cannot manually downgrade FXOS, so if you find yourself in this situation and you want to run a recommended combination, you will need a full reimage.

Sometimes we release updated builds. In most cases, only the latest build for each platform is available on the Cisco Support & Download site. We strongly recommend you use the latest build. If you downloaded an earlier build, do not use it.

You cannot upgrade from one build to another for the same software version. If you are already running an affected build, determine if an upgrade or hotfix would work instead. If not, contact Cisco TAC. See the Cisco Firepower Hotfix Release Notes for quicklinks to publicly available hotfixes.
