Release Notes for Cisco Catalyst 9300 Series Switches, Cisco IOS XE Gibraltar 16.11.x
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.

Description, Documentation Link and License Level Information |
---|---|
BGP PE-CE support for MPLS Layer 3 VPNs |
Supports BGP as a routing protocol between the provider edge (PE) device and the customer edge (CE) device.
See Configuring MPLS Layer 3 VPN.
(Network Advantage) |
Consent Token for Shell Access |
Authenticates a network administrator’s request to access the system shell. When debugging software issues, a Cisco TAC engineer may have to work with a network administrator to collect debug information or perform live debugging on a production system. This feature provides the network administrator with privileged, restricted, and secure access to the system shell with mutual consent from the network administrator and Cisco TAC.
See System Management → Consent Token.
(Network Essentials and Network Advantage) |
ERSPAN Termination |
Introduces support for encapsulated remote switched port analyzer (ERSPAN) type 3 source feature and the following ERSPAN type 2 and type 3 features:
The header-type 3 , destination , ip dscp , filter mtu , and vrf commands are available for configuration.
See Network Management → Configuring ERSPAN.
(DNA Advantage) |
Ingress Replication (IR) for VXLAN BGP EVPN |
Enables forwarding of broadcast, unknown unicast, and multicast (BUM) traffic to the relevant recipients in a network. IR is a unicast approach to handling multi-destination traffic, and involves an ingress device replicating every BUM packet and then sending it as a separate unicast to remote egress devices.
See Layer 2 → Configuring VXLAN BGP EVPN.
(Network Advantage) |
IPv6: DHCP Client |
IPv6 support is introduced for the DHCP client feature.
(Network Essentials and Network Advantage) |
IPv6: IP Service Level Agreements (SLAs) |
IPv6 support is introduced for following IP SLA features:
See Network Management → Configuring Service Level Agreements.
(Network Essentials and Network Advantage) |
IPv6: IPv6 Multicast Virtual Private Network (MVPNv6) |
Enables service providers to use their existing IPv4 backbone to provide multicast-enabled private IPv6 networks to their customers.
See IP Multicast Routing → Configuring Multicast Virtual Private Network
(Network Advantage) |
IPv6: Open Shortest Path First (OSPF) |
IPv6 support is introduced for following OSPF features:
See IP Routing.
(Network Essentials and Network Advantage) |
IPv6: OSPF Limit on Number of Redistributed Routes |
Enables you to configure a maximum number of prefixes (routes) that can be redistributed into OSPFv3 from other protocols or other OSPFv3 processes. Such a limit helps prevent the device from being flooded by too many redistributed routes.
See IP Routing → Configuring OSPFv3 Limit on Number of Redistributed Routes.
(Network Essentials and Network Advantage) |
IPv6: RFC 5453 Reserved IPv6 Interface Identifiers |
An autoconfigured IPv6 address will contain interface identifiers that are not part of the reserved range of interface identifiers specified in RFC 5453.
See IP Multicast Routing → IP Multicast Routing Technology Overview.
(Network Essentials and Network Advantage) |
IPv6 Downloadable ACL (DACL) |
Applies per-port IPv6 access-layer restrictions based on Identity Services Engine (ISE) profiles.
See Security → IPv6 ACLs.
(Network Essentials and Network Advantage) |
IPv6 Support for Virtual Extensible LAN (VXLAN) Border Gateway Protocol (BGP) Ethernet VPN (EVPN) in Routed Mode |
Introduces IPv6 support for the VXLAN BGP EVPN operation in routed mode. A VXLAN is a network overlay that allows layer 2 segments to be stretched across an IP core. All the benefits of Layer 3 topologies are thereby available with VXLAN. The overlay protocol is VXLAN and BGP uses EVPN as the address family for communicating end host MAC and IP addresses. VXLAN BGP EVPN operates in bridged mode when the hosts are in the same subnet, and in routed mode when the hosts are in different subnets.
See Layer 2 → Configuring VXLAN BGP EVPN.
(Network Advantage) |
Multiprotocol Label Switching (MPLS)
|
See Multiprotocol Label Switching.
(Network Advantage) |
Password Configuration: Secure Password Migration |
Introduces support for migration of type 0 and type 7 usernames and passwords to type 6. Password protection restricts access to a network or network device. Encrypting passwords provides an additional layer of security, particularly for passwords that cross the network or are stored on a TFTP server. Starting with this release, the switch supports automatic conversion of usernames and passwords with type 0 and type 7 encryption, to type 6 encryption. Type-6 is a strong, reversible 128-bit Advanced Encryption Standard (AES) password encryption. To start using type-6 encryption, you must enable the AES password encryption feature and configure a primary encryption key, which is used to encrypt and decrypt passwords.
See Security → Controlling Switch Access with Passwords and Privilege Levels.
(Network Essentials and Network Advantage) |
Programmability
|
The following programmability features are introduced in this release:
See Programmability.
(Network Essentials and Network Advantage) |
Smart Licensing: System Messages for an Evaluation License |
Evaluation licenses that are not registered will still expire after the 90-day period, but warning system messages about an evaluation license expiry will now be generated only 275 days after this 90-day window.
See License Levels - Usage Guidelines.
(A license level does not apply) |
Supported Spanning-Tree Instances |
In per-VLAN spanning-tree plus (PVST+), Rapid PVST+ mode, the device or device stack now supports up to 256 spanning-tree instances.
See Layer 2.
(Network Essentials and Network Advantage) |
Time Domain Reflectometer (TDR) |
Determines if a cable is OPEN or SHORT when it is at fault. This involves running a TDR test, which detects a cable fault by sending a signal through the cable and reading the signal that is reflected back. To run the test, enter the test cable-diagnostics tdr command in privileged EXEC mode; to display test results, enter the show cable-diagnostics tdr command in privileged EXEC mode.
See Interface and Hardware Components → Checking Port Status and Connectivity.

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

Automatic Boot Loader Upgrade
When you upgrade from the existing release on your switch to a later or newer release for the first time, the boot loader may be automatically upgraded, based on the hardware version of the switch. If the boot loader is automatically upgraded, it will take effect on the next reload. If you go back to the older release after this, the boot loader is not downgraded. The updated boot loader supports all previous releases.
For subsequent Cisco IOS XE Everest 16.x.x, or Cisco IOS XE Fuji 16.x.x releases, if there is a new bootloader in that release, it may be automatically upgraded based on the hardware version of the switch when you boot up your switch with the new image for the first time.
Caution |
Do not power cycle your switch during the upgrade. |
Scenario |
Automatic Boot Loader Response |
---|---|
If you boot Cisco IOS XE Gibraltar 16.11.1 first time |
On Cisco Catalyst 9300 Series Switches, the boot loader may be upgraded to version 16.10.1r[FC1]. For example:
When using install commands to upgrade software, you may see this during the install operation:
|
Automatic Microcode Upgrade
During a Cisco IOS image upgrade or downgrade on a PoE or UPoE switch, microcode is upgraded to reflect applicable feature enhancements and bug fixes. A microcode upgrade occurs only during an image upgrade or downgrade, on PoE or UPoE switches. It does not occur during switch reloads or on non-PoE switches.
Depending on the release you are upgrading from, microcode upgrade can occur during the install operation or during bootup:
-
If the release you are upgrading from does not support microcode updates during the course of installation, microcode is updated during boot up, and an additional 4 minutes (approximately) are required to complete the microcode upgrade, in addition to the normal reload time. Data traffic is not forwarded when microcode is upgraded during bootup.
-
When using install commands to upgrade, microcode is upgraded during the install operation, and no additional time is required during bootup. Here microcode is updated before the reload that occurs as part of the image upgrade process. Data traffic continues to be forwarded during the upgrade.
Do not restart the switch during the upgrade or downgrade process.

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 Digital Network Architecture Center (Cisco DNA 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.
License Types
The following license types are available:
-
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.
License Levels - Usage Guidelines
-
Base licenses (Network Essentials and Network-Advantage) are ordered and fulfilled only with a permanent license type.
-
Add-on licenses (DNA Essentials and DNA Advantage) are ordered and fulfilled only with a 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:
Table 3. 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.
Cisco Smart Licensing
Cisco Smart Licensing is a flexible licensing model that provides you with an easier, faster, and more consistent way to purchase and manage software across the Cisco portfolio and across your organization. And it’s secure – you control what users can access. With Smart Licensing you get:
-
Easy Activation: Smart Licensing establishes a pool of software licenses that can be used across the entire organization—no more PAKs (Product Activation Keys).
-
Unified Management: My Cisco Entitlements (MCE) provides a complete view into all of your Cisco products and services in an easy-to-use portal, so you always know what you have and what you are using.
-
License Flexibility: Your software is not node-locked to your hardware, so you can easily use and transfer licenses as needed.
To use Smart Licensing, you must first set up a Smart Account on Cisco Software Central (http://software.cisco.com).
Important |
Cisco Smart Licensing is the default and the only available method to manage licenses. |
For a more detailed overview on Cisco Licensing, go to cisco.com/go/licensingguide.
Deploying Smart Licensing
The following provides a process overview of a day 0 to day N deployment directly initiated from a device that is running Cisco IOS XE Fuji 16.9.1 or later releases. Links to the configuration guide provide detailed information to help you complete each one of the smaller tasks.
Procedure
Step 1 |
Begin by establishing a connection from your network to Cisco Smart Software Manager on cisco.com. In the software configuration guide of the required release, see System Management → Configuring Smart Licensing → Connecting to CSSM |
Step 2 |
Create and activate your Smart Account, or login if you already have one. To create and activate Smart Account, go to Cisco Software Central → Create Smart Accounts. Only authorized users can activate the Smart Account. |
Step 3 |
Complete the Cisco Smart Software Manager set up. |
With this,
-
The device is now in an authorized state and ready to use.
-
The licenses that you have purchased are displayed in your Smart Account.
Using Smart Licensing on an Out-of-the-Box Device
Starting from Cisco IOS XE Fuji 16.9.1, if an out-of-the-box device has the software version factory-provisioned, all licenses on such a device remain in evaluation mode until registered in Cisco Smart Software Manager.
In the software configuration guide of the required release, see System Management → Configuring Smart Licensing → Registering the Device in CSSM
How Upgrading or Downgrading Software Affects Smart Licensing
Starting from Cisco IOS XE Fuji 16.9.1, Smart Licensing is the default and only license management solution; all licenses are managed as Smart Licenses.
Important |
Starting from Cisco IOS XE Fuji 16.9.1, the Right-To-Use (RTU) licensing mode is deprecated, and the associated license right-to-use command is no longer available on the CLI. |
Note how upgrading to a release that supports Smart Licensing or moving to a release that does not support Smart Licensing affects licenses on a device:
-
When you upgrade from an earlier release to one that supports Smart Licensing—all existing licenses remain in evaluation mode until registered in Cisco Smart Software Manager. After registration, they are made available in your Smart Account.
In the software configuration guide of the required release, see System Management → Configuring Smart Licensing → Registering the Device in CSSM
-
When you downgrade to a release where Smart Licensing is not supported—all smart licenses on the device are converted to traditional licenses and all smart licensing information on the device is removed.
Scaling Guidelines
For information about feature scaling guidelines, see the Cisco Catalyst 9300 Series Switches datasheet at:
Limitations and Restrictions
-
Cisco TrustSec restrictions—Cisco TrustSec can be configured only on physical interfaces, not on logical interfaces.
-
Control Plane Policing (CoPP): The show run command does not display information about classes configured under
system-cpp policy
, when they are left at default values. Use the show policy-map system-cpp-policy or the show policy-map control-plane commands in privileged EXEC mode instead. -
Flexible NetFlow limitations
-
You cannot configure NetFlow export using the Ethernet Management port (GigabitEthernet0/0).
-
You can not configure a flow monitor on logical interfaces, such as switched virtual interfaces (SVIs), port-channel, loopback, tunnels.
-
You can not configure multiple flow monitors of same type (ipv4, ipv6 or datalink) on the same interface for same direction.
-
-
QoS restrictions
-
When configuring QoS queuing policy, the sum of the queuing buffer should not exceed 100%.
-
For QoS policies, only switched virtual interfaces (SVI) are supported for logical interfaces.
-
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.
-
-
Stacking:
-
A switch stack supports up to eight stack members.
-
Mixed stacking is not supported. Cisco Catalyst 9300 Series Switches cannot be stacked with Cisco Catalyst 3850 Series Switches.
-
Auto upgrade for a new member switch is supported only in the install 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
-
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.
-
Secure Password Migration—Type 6 encrypted password is supported from Cisco IOS XE Gibraltar 16.10.1 and later releases. Autoconversion to password type 6 is supported from Cisco IOS XE Gibraltar 16.11.1 and later releases.
If the startup configuration has a type 6 password and you downgrade to a version in which type 6 password is not supported, you can/may be locked out of the device.
-
The File System Check (fsck) utility is not supported in install mode.
Caveats
Caveats describe unexpected behavior in Cisco IOS-XE releases. Caveats listed as open in a prior release are carried forward to the next release as either open or resolved.
Cisco Bug Search Tool
The Cisco Bug Search Tool (BST) allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data such as bug details, product, and version. The BST is designed to improve the effectiveness in network risk management and device troubleshooting. The tool has a provision to filter bugs based on credentials to provide external and internal bug views for the search input.
