Introduction

Cisco Catalyst 9300 Series Switches are Cisco’s lead stackable access platforms for the next-generation enterprise and have been purpose-built to address emerging trends of Security, IoT, Mobility, and Cloud.

They deliver complete convergence with the rest of the Cisco Catalyst 9000 Series Switches in terms of ASIC architecture with a Unified Access Data Plane (UADP) 2.0. The platform runs an Open Cisco IOS XE that supports model driven programmability, has the capacity to host containers, and run 3rd party applications and scripts natively within the switch (by virtue of x86 CPU architecture, local storage, and a higher memory footprint). This series forms the foundational building block for SD-Access, which is Cisco’s lead enterprise architecture.

What's New in Cisco IOS XE 17.15.x

Hardware Features in Cisco IOS XE 17.15.1

There are no new hardware features in this release.

Software Features in Cisco IOS XE 17.15.1

Feature Name

Description

AAA PAC-less Authentication

In multi ISE node environment when the primary ISE node is unavailable, device can automatically switch to the secondary node without needing to re-establish a Provisioning Authentication Credential (PAC), ensuring minimal disruption.

AAA PAC-less authentication simplifies the authentication process by eliminating the need for a PAC, improves scalability, enhances the user experience, and enables more modern authentication methods while aligning with Zero Trust security principles.

See Cisco TrustSec → Cisco TrustSec Overview.

(Network Essentials)

AWS S3 and CloudWatch Support

Cisco Catalyst 9000 Series Switches support Amazon Web Services S3 and CloudWatch. With AWS S3, network administrators can mount an Amazon Simple Storage Service (S3) bucket to the bootflash. The S3 bucket enables easy distribution of software images, software maintenance upgrades (SMUs), and scripts to multiple devices without any disruptions. Network administrators can also create, edit, and delete the cloud storage instance using AWS S3 functionality, and make them accessible as part of the bootflash.

The AWS CloudWatch is a monitoring and logging service that provides data that enables you to understand, optimize, and enhance the performance of your applications, systems, and services running on the Cloud platform and on-premise servers.

Energy Consumption Visibility

This feature provides system energy consumption information in the output of the show power detail command, and Power over Ethernet (PoE) energy consumption information in the output of the newly introduced show power inline meter command. This information can be used to check the power efficiency of the setup.

See Interface and Hardware Components → Configuring Internal Power Supplies and Configuring Power over Ethernet.

(Network Essentials)

Port Settings Configuration for Interfaces

The port-settings command is introduced. The port-settings command can simultaneously or separately configure the speed, duplex, and auto negotiation for an interface, an interface range, or a port channel interface.

When using a single command to configure multiple parameters of the port-settings command, the order must be, speed, duplex, and autoneg. If you specify speed first, you can configure duplex and autoneg for the interface. If you specify duplex first, you can only configure autoneg. And, if you specify autoneg first, you cannot configure speed or duplex.

See Interface and Hardware Components → Configuring Interface Characteristics.

(Network Essentials)

Programmability:

  • YANG Data Models

The following programmability features are introduced in this release:

See Programmability.

(Network Essentials and Network Advantage)

Unique BGP Identifier for BGP-4

Enhancement to Border Gateway Protocol (BGP) IPv4 router-id, added support for RFC 6286, which allows configuring IPv4 multicast and local range addresses as BGP router-ID, in addition to allowing peers with the same BGP router-ID and different ASes to establish a BGP connection.

(Network Advantage)

New on the WebUI

There are no new WebUI features in this release.

    • You can not configure a flow monitor on logical interfaces, such as layer 2 port-channels, loopback, tunnels.

    • You can not configure multiple flow monitors of same type (ipv4, ipv6 or datalink) on the same interface for same direction.

  • Hardware Limitations (Optics):

    • SFP-10G-T-X supports 100Mbps/1G/10G speeds based on auto negotiation with the peer device. 10Mbps speed is not supported and you cannot force speed settings from the transceiver.

    • PHY Loopback test is not supported on SFP-10G-T-X.

  • QoS restrictions

    • When configuring QoS queuing policy, the sum of the queuing buffer should not exceed 100%.

    • Policing and marking policy on sub interfaces is supported.

    • Marking policy on switched virtual interfaces (SVI) is supported.

    • QoS policies are not supported for port-channel interfaces, tunnel interfaces, and other logical interfaces.

    • Stack Queuing and Scheduling (SQS) drops CPU bound packets exceeding 1.4 Gbps.

  • Secure Shell (SSH)

    • Use SSH Version 2. SSH Version 1 is not supported.

    • When the device is running SCP and SSH cryptographic operations, expect high CPU until the SCP read process is completed. SCP supports file transfers between hosts on a network and uses SSH for the transfer.

      Since SCP and SSH operations are currently not supported on the hardware crypto engine, running encryption and decryption process in software causes high CPU. The SCP and SSH processes can show as much as 40 or 50 percent CPU usage, but they do not cause the device to shutdown.

  • Smart Licensing Using Policy: Starting with Cisco IOS XE Amsterdam 17.3.2a, with the introduction of Smart Licensing Using Policy, even if you configure a hostname for a product instance or device, only the Unique Device Identifier (UDI) is displayed. This change in the display can be observed in all licensing utilities and user interfaces where the hostname was displayed in earlier releases. It does not affect any licensing functionality. There is no workaround for this limitation.

    The licensing utilities and user interfaces that are affected by this limitation include only the following: Cisco Smart Software Manager (CSSM), Cisco Smart License Utility (CSLU), and Smart Software Manager On-Prem (SSM On-Prem).

    This limitation is removed from Cisco IOS XE Cupertino 17.9.1. If you configure a hostname and disable hostname privacy (no license smart privacy hostname global configuration command), hostname information is sent from the product instance and displayed on the applicable user interfaces (CSSM, CSLU, SSM On-Prem). For more information, see the command reference for this release.

  • Stacking:

    • A switch stack supports up to eight stack members.

    • Mixed stacking is supported between C9300 and C9300X SKUs and between C9300L and C9300LM SKUs only.

      This additional restriction applies to the C9300-24UB, C9300-24UXB, and C9300-48UB models of the series: These models can be stacked only with each other. They cannot be stacked with other C9300 SKUs.

    • Auto upgrade for a new member switch is supported only in the install mode.

  • TACACS legacy command: Do not configure the legacy tacacs-server host command; this command is deprecated. If the software version running on your device is Cisco IOS XE Gibraltar 16.12.2 or a later release, using the legacy command can cause authentication failures. Use the tacacs server command in global configuration mode.

  • USB Authentication: When you connect a Cisco USB drive to the switch, the switch tries to authenticate the drive against an existing encrypted preshared key. Since the USB drive does not send a key for authentication, the following message is displayed on the console when you enter password encryption aes command:
    Device(config)# password encryption aes
Master key change notification called without new or old key

  • Catatyst 9000 Series Switches support MACsec switch-to-switch connections. We do not recommend configuring MACsec switch-to-host connections in an overlay network. For assistance with an existing switch-to-host MACsec implementation or a design review, contact your Cisco Sales Representative or Channel Partner.

  • VLAN Restriction: It is advisable to have well-defined segregation while defining data and voice domain during switch configuration and to maintain a data VLAN different from voice VLAN across the switch stack. If the same VLAN is configured for data and voice domains on an interface, the resulting high CPU utilization might affect the device.

  • Wired Application Visibility and Control limitations:

    • NBAR2 (QoS and Protocol-discovery) configuration is allowed only on wired physical ports. It is not supported on virtual interfaces, for example, VLAN, port channel nor other logical interfaces.

    • NBAR2 based match criteria ‘match protocol’ is allowed only with marking or policing actions. NBAR2 match criteria will not be allowed in a policy that has queuing features configured.

    • ‘Match Protocol’: up to 256 concurrent different protocols in all policies.

    • NBAR2 and Legacy NetFlow cannot be configured together at the same time on the same interface. However, NBAR2 and wired AVC Flexible NetFlow can be configured together on the same interface.

    • Only IPv4 unicast (TCP/UDP) is supported.

    • AVC is not supported on management port (Gig 0/0)

    • NBAR2 attachment should be done only on physical access ports. Uplink can be attached as long as it is a single uplink and is not part of a port channel.

    • Performance: Each switch member is able to handle 2000 connections per second (CPS) at less than 50% CPU utilization. Above this rate, AVC service is not guaranteed.

    • Scale: Able to handle up to 20000 bi-directional flows per 24 access ports and per 48 access ports.

  • YANG data modeling limitation: A maximum of 20 simultaneous NETCONF sessions are supported.

  • Embedded Event Manager: Identity event detector is not supported on Embedded Event Manager.

  • The File System Check (fsck) utility is not supported in install mode.

  • The command service-routing mdns-sd is being deprecated. Use the mdns-sd gateway command instead.

Licensing

This section provides information about the licensing packages for features available on Cisco Catalyst 9000 Series Switches.

License Levels

The software features available on Cisco Catalyst 9300 Series Switches fall under these base or add-on license levels.

Base Licenses

  • Network Essentials

  • Network Advantage—Includes features available with the Network Essentials license and more.

Add-On Licenses

Add-On Licenses require a Network Essentials or Network Advantage as a pre-requisite. The features available with add-on license levels provide Cisco innovations on the switch, as well as on the Cisco Catalyst Center.

  • DNA Essentials

  • DNA Advantage— Includes features available with the DNA Essentials license and more.

To find information about platform support and to know which license levels a feature is available with, use Cisco Feature Navigator. To access Cisco Feature Navigator, go to https://cfnng.cisco.com. An account on cisco.com is not required.

Usage Guidelines

This section provides the guidelines for license levels.

  • The duration or term for which a purchased license is valid:

    Smart Licensing Using Policy

    Smart Licensing

    • Perpetual: There is no expiration date for such a license.

    • Subscription: The license is valid only until a certain date (for a three, five, or seven year period).

    • Permanent: for a license level, and without an expiration date.

    • Term: for a license level, and for a three, five, or seven year period.

    • Evaluation: a license that is not registered.

  • Base licenses (Network Essentials and Network-Advantage) are ordered and fulfilled only with a perpetual or permanent license type.

  • Add-on licenses (DNA Essentials and DNA Advantage) are ordered and fulfilled only with a subscription or term license type.

  • An add-on license level is included when you choose a network license level. If you use DNA features, renew the license before term expiry, to continue using it, or deactivate the add-on license and then reload the switch to continue operating with the base license capabilities.

  • When ordering an add-on license with a base license, note the combinations that are permitted and those that are not permitted:

    Permitted Combinations

    DNA Essentials

    DNA Advantage

    Network Essentials

    Yes

    No

    Network Advantage

    Yes5

    Yes
    5 You will be able to purchase this combination only at the time of the DNA license renewal and not when you purchase DNA-Essentials the first time.

  • Evaluation licenses cannot be ordered. They are not tracked via Cisco Smart Software Manager and expire after a 90-day period. Evaluation licenses can be used only once on the switch and cannot be regenerated. Warning system messages about an evaluation license expiry are generated only 275 days after expiration and every week thereafter. An expired evaluation license cannot be reactivated after reload. This applies only to Smart Licensing. The notion of evaluation licenses does not apply to Smart Licensing Using Policy.

Available Licensing Models and Configuration Information

  • Cisco IOS XE Fuji 16.8.x and earlier: RTU Licensing is the default and the only supported method to manage licenses.

  • Cisco IOS XE Fuji 16.9.1 to Cisco IOS XE Amsterdam 17.3.1: Smart Licensing is the default and the only supported method to manage licenses.

    In the software configuration guide of the required release, see System Management → Configuring Smart Licensing.

  • Cisco IOS XE Amsterdam 17.3.2a and later: Smart Licensing Using Policy, which is an enhanced version of Smart Licensing, is the default and the only supported method to manage licenses.

    In the software configuration guide of the required release (17.3.x onwards), see System Management → Smart Licensing Using Policy.

For a more detailed overview on Cisco Licensing, go to cisco.com/go/licensingguide.

Switch Software Version Information

This section provides information about software, images, and ROMMON, and Field-Programmable Gate Array (FGPA) versions.

Finding the Software Version

The package files for the Cisco IOS XE software are stored on the system board flash device (flash:).

You can use the show version privileged EXEC command to see the software version that is running on your switch.

 Note
Although the show version output always shows the software image running on the switch, the model name shown at the end of this display is the factory configuration and does not change if you upgrade the software license.

You can also use the dir filesystem: privileged EXEC command to see the directory names of other software images that you might have stored in flash memory.

Finding the Software Images

To download software images, visit the software downloads page: Cisco Catalyst 9300 Series Switches.

ROMMON Versions

ROMMON, also known as the boot loader, is firmware that runs when the device is powered up or reset. It initializes the processor hardware and boots the operating system software (Cisco IOS XE software image). The ROMMON is stored on the following Serial Peripheral Interface (SPI) flash devices on your switch:

  • Primary: The ROMMON stored here is the one the system boots every time the device is powered-on or reset.

  • Golden: The ROMMON stored here is a backup copy. If the one in the primary is corrupted, the system automatically boots the ROMMON in the golden SPI flash device.

ROMMON upgrades may be required to resolve firmware defects, or to support new features, but there may not be new versions with every release.

Field-Programmable Gate Array Version Upgrade

A field-programmable gate array (FPGA) is a type of programmable memory device that exists on Cisco switches. They are re-configurable logic circuits that enable the creation of specific and dedicated functions.

To check the current FPGA version, enter the version -v command in ROMMON mode.

 Note

  • Not every software release has a change in the FPGA version.

  • The version change occurs as part of the regular software upgrade and you do not have to perform any other additional steps.

Upgrading and Downgrading the Switch Software

This section covers the various aspects of upgrading or downgrading the device software.

 Note
You cannot use the Web UI to install, upgrade, or downgrade device software.

Upgrading in Install Mode

Follow these instructions to upgrade from one release to another, in install mode. To perform a software image upgrade, you must be booted into IOS through boot flash:packages.conf .

Before you begin

Note that you can use this procedure for the following upgrade scenarios:

When upgrading from ...

Use these commands...

To upgrade to...

Cisco IOS XE Everest 16.5.1a or Cisco IOS XE Everest 16.6.1

Only request platform software commands

Cisco IOS XE 17.15.x

Cisco IOS XE Everest 16.6.2 and all later releases

Either install commands or request platform software commands6.

6 The request platform software commands are deprecated. So although they are still visible on the CLI, we recommend that you use install commands.

This procedure shows the steps to upgrade the Cisco IOS XE software on a switch, from Cisco IOS XE 17.14.1 to Cisco IOS XE 17.15.1 using install commands, followed by sample output.

Procedure

Step 1

Clean-up

install remove inactive

Use this command to clean-up old installation files in case of insufficient space and to ensure that you have at least 1GB of space in flash, to expand a new image.

Step 2

Copy new image to flash

  1. copy tftp:[[//location]/directory]/filenameflash:

    Use this command to copy the new image from a TFTP server to flash memory. The location is either an IP address or a host name. The filename is specified relative to the directory used for file transfers. Skip this step if you want to use the new image from a TFTP server.

  2. dir flash:

    Use this command to confirm that the image has been successfully copied to flash.

Step 3

Set boot variable

  1. no boot system

    Use this command to reset the boot variable. This command removes the startup system image specification. Otherwise, the switch may boot a previously configured boot image.

  2. boot system flash:packages.conf

    Use this command to set the boot variable to flash:packages.conf .

  3. no boot manual

    Use this command to configure the switch to auto-boot.

  4. write memory

    Use this command to save boot settings.

  5. show boot

    Use this command to verify the boot variable (packages.conf) and manual boot setting (no):

Step 4

Install image to flash

install add file activate commit

Use this command to install the image.

We recommend that you point to the source image on your TFTP server or the flash drive of the active switch, if you have copied the image to flash memory. If you point to an image on the flash or USB drive of a member switch (instead of the active), you must specify the exact flash or USB drive - otherwise installation fails. For example, if the image is on the flash drive of member switch 3 (flash-3): Switch# install add file flash-3:cat9k_iosxe.17.15.01.SPA.bin activate commit.

 Note
The system reloads automatically after executing the install add file activate commit command. You do not have to manually reload the system.

Step 5

Verify installation

After the software has been successfully installed, use the dir flash: command to verify that the flash partition has ten new .pkg files and two .conf files.

  1. dir flash:*.pkg

  2. dir flash:*.conf

Step 6

show version

After the image boots up, use this command to verify the version of the new image.

Example

The following sample output displays the cleaning up of unused files, by using the install remove inactive command:
Switch# install remove inactive

Downgrading in Install Mode

Follow these instructions to downgrade from one release to another, in install mode. To perform a software image downgrade, you must be booted into IOS through boot flash:packages.conf .

Before you begin

Note that you can use this procedure for the following downgrade scenarios:

When downgrading from ...

Use these commands...

To downgrade to...

Cisco IOS XE 17.15.x

Either install commands or request platform software command7.

Cisco IOS XE 17.14.x or earlier releases.

7 The request platform software commands are deprecated. So although they are still visible on the CLI, we recommend that you use install commands.
 Note
New switch models that are introduced in a release cannot be downgraded. The release in which a switch model is introduced is the minimum software version for that model.

This procedure shows the steps to downgrade the Cisco IOS XE software on a switch, from Cisco IOS XE 17.15.1 to Cisco IOS XE 17.14.1 using install commands, followed by sample output.

Microcode Downgrade Prerequisite:

Starting from Cisco IOS XE Gibraltar 16.12.1, a new microcode is introduced to support IEEE 802.3bt Type 3 standard for UPOE switches in the series (C9300-24U, C9300-48U, C9300-24UX, C9300-48UXM, C9300-48UN). The new microcode is not backward-compatible with some releases, because of which you must also downgrade the microcode when you downgrade to one of these releases. If the microcode is not downgraded, PoE features will be impacted after the downgrade.

Depending on the release you are downgrading to and the commands you use to downgrade, review the table below for the action you may have to take:

When downgrading from ...

To one of These Releases

by Using...

Action For Microcode Downgrade

Cisco IOS XE Gibraltar 16.12.1 or a later release

Cisco IOS XE Everest 16.6.1 through Cisco IOS XE Everest 16.6.6

Cisco IOS XE Fuji 16.9.1 through Cisco IOS XE Fuji 16.9.2

install commands

Microcode will roll back automatically as part of the software installation. No further action is required.

request platform software commands or or bundle boot

Manually downgrade the microcode before downgrading the software image.

Enter the hw-module mcu rollback command in global configuration mode, to downgrade microcode.

Procedure

Step 1

Clean-up

install remove inactive

Use this command to clean-up old installation files in case of insufficient space and to ensure that you have at least 1GB of space in flash, to expand a new image.

Step 2

Copy new image to flash

  1. copy tftp:[[//location]/directory]/filenameflash:

    Use this command to copy the new image from a TFTP server to flash memory. The location is either an IP address or a host name. The filename is specified relative to the directory used for file transfers. Skip this step if you want to use the new image from a TFTP server.

  2. dir flash:

    Use this command to confirm that the image has been successfully copied to flash.

Step 3

Set boot variable

  1. boot system flash:packages.conf

    Use this command to set the boot variable to flash:packages.conf .

  2. no boot manual

    Use this command to configure the switch to auto-boot.

  3. write memory

    Use this command to save boot settings.

  4. show boot

    Use this command to verify the boot variable (packages.conf) and manual boot setting (no):

Step 4

Downgrade software image

install add file activate commit

Use this command to install the image.

We recommend that you point to the source image on your TFTP server or the flash drive of the active switch, if you have copied the image to flash memory. If you point to an image on the flash or USB drive of a member switch (instead of the active), you must specify the exact flash or USB drive - otherwise installation fails. For example, if the image is on the flash drive of member switch 3 (flash-3): Switch# install add file flash-3:cat9k_iosxe.17.14.01.SPA.bin activate commit.

 Note
The system reloads automatically after executing the install add file activate commit command. You do not have to manually reload the system.

Step 5

Verify version

show version

After the image boots up, use this command to verify the version of the new image.

 Note
When you downgrade the software image, the ROMMON version does not downgrade. It remains updated.

Upgrading the ROMMON

To know the ROMMON or bootloader version that applies to every major and maintenance release, see ROMMON Versions.

You can upgrade the ROMMON before, or, after upgrading the software version. If a new ROMMON version is available for the software version you are upgrading to, proceed as follows:

  • Upgrading the ROMMON in the primary SPI flash device

    This ROMMON is upgraded automatically. When you upgrade from an existing release on your switch to a later or newer release for the first time, and there is a new ROMMON version in the new release, the system automatically upgrades the ROMMON in the primary SPI flash device, based on the hardware version of the switch.

  • Upgrading the ROMMON in the golden SPI flash device

    You must manually upgrade this ROMMON. Enter the upgrade rom-monitor capsule golden switch command in privileged EXEC mode.

     Note

    • In case of a switch stack, perform the upgrade on the active switch and all members of the stack.

After the ROMMON is upgraded, it will take effect on the next reload. If you go back to an older release after this, the ROMMON is not downgraded. The updated ROMMON supports all previous releases.

Accessing Hidden Commands

Starting with Cisco IOS XE Fuji 16.8.1a, as an improved security measure, the way in which hidden commands can be accessed has changed.

Hidden commands have always been present in Cisco IOS XE, but were not equipped with CLI help. That is, entering a question mark (?) at the system prompt did not display the list of available commands. These commands were only meant to assist Cisco TAC in advanced troubleshooting and were not documented either.

Starting with Cisco IOS XE Fuji 16.8.1a, hidden commands are available under:

  • Category 1—Hidden commands in privileged or User EXEC mode. Begin by entering the service internal command to access these commands.

  • Category 2—Hidden commands in one of the configuration modes (global, interface and so on). These commands do not require the service internal command.

Further, the following applies to hidden commands under Category 1 and 2:

  • The commands have CLI help. Enter enter a question mark (?) at the system prompt to display the list of available commands.

    Note: For Category 1, enter the service internal command before you enter the question mark; you do not have to do this for Category 2.

  • The system generates a %PARSER-5-HIDDEN syslog message when a hidden command is used. For example: 
    *Feb 14 10:44:37.917: %PARSER-5-HIDDEN: Warning!!! 'show processes memory old-header ' is a hidden command. 
Use of this command is not recommended/supported and will be removed in future.

Apart from category 1 and 2, there remain internal commands displayed on the CLI, for which the system does NOT generate the %PARSER-5-HIDDEN syslog message.

 Important

We recommend that you use any hidden command only under TAC supervision.

If you find that you are using a hidden command, open a TAC case for help with finding another way of collecting the same information as the hidden command (for a hidden EXEC mode command), or to configure the same functionality (for a hidden configuration mode command) using non-hidden commands.
