Release Notes for Cisco Catalyst 9300 Series Switches, Cisco IOS XE Bengaluru 17.4.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.

Software Features in Cisco IOS XE Bengaluru 17.4.1

Feature Name

Description, Documentation Link, and License Level Information

BGP Large Community

Introduces support for BGP large communities attribute which provides the capability for tagging routes and modifying BGP routing policy on devices. They are similar to BGP communities attributes, but with a twelve octet size.

See IP Routing → Configuring BGP Large Community

Device Classifier Profiles

Allows you to configure the rules for matching and classifying the device using device classifier conditions.

See Interface and Hardware Components → Configuring Auto SmartPorts.

Line Configuration for Disabling Auto-Consolidation

Introduces support for the no line auto-consolidation command in line configuration mode. This command disables the auto consolidation of line commands during the nonvolatile generation (NVGEN) process.

See System Management →Line Auto Consolidation

VRF-Aware RADIUS Automated Tester

Allows you to configure RADIUS automated tester for a non-default VRF. With this, the automated tester can access information about VRF and source-interface from the global source-interface and avoids marking the server as DEAD.

See Security →VRF Aware Radius Automated Testing

Programmability

  • OpenFlow Rewrite Fields

  • Application Hosting on Internal Flash for Cisco Signed Applications

  • YANG Data Models

The following programmability features are introduced in this release:

  • OpenFlow Rewrite Fields: Introduces support for rewriting ipv4_src, ipv4_dst, icmpv4_type, tcp_src, udp_src, tcp_dst, udp_dst, ip_dscp fields .

  • Application Hosting on Internal Flash for Cisco Signed Applications: Introduces support for application hosting on bootflash. The iox command in the global configuration mode creates an IOx bootflash partition for hosting applications.

  • YANG Data Models: For the list of Cisco IOS XE YANG models available with this release, navigate to: https://github.com/YangModels/yang/tree/master/vendor/cisco/xe/1741.

    Revision statements embedded in the YANG files indicate if there has been a model revision. The README.md file in the same GitHub location highlights changes that have been made in the release.


(Network Essentials and Network Advantage)

New on the Web UI

  • Smart Licensing Using Policy

  • Stealthwatch Cloud support for NetFlow monitoring

Use the WebUI for:

  • Smart Licensing Using Policy—Any new licenses that you purchase are added to a Cisco Smart Account. Smart licenses are no longer device-specific, but organization-specific. You can create separate Virtual Accounts for different departments in your organization and assign licenses to them from the centralized pool, thereby improving license portability and efficient consumption.

    Different Virtual Accounts can be assigned licenses that can be used to register product instances using a registration token. When a device is no longer in use by a department, the license can be provisioned to another department or pooled back to the Smart Account. Also, you can choose the deployment option, based on your security profile, such as direct, on-premise, and offline.

  • Stealthwatch Cloud support for NetFlow monitoring—Allows you to monitor packets to detect threats and security vulnerabilities in your public cloud network powered by Cisco Stealthwatch Cloud.

Serviceability

show etherchannel

The command was modified. The platform keyword was introduced. It displays summary of channel-group for the specified platform.

Important Notes

Unsupported Features

  • Cisco TrustSec Network Device Admission Control (NDAC) on Uplinks

  • Converged Access for Branch Deployments

  • IPsec VPN

  • Performance Monitoring (PerfMon)

  • Resilient Ethernet Protocol (REP) (REP is not supported only in this release. See CSCvv91619 and CSCvw17155).

  • ThousandEyes Enterprise Agent

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.

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.

ROMMON Upgrades

The ROM monitor (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. To know the ROMMON or bootloader version that applies to every major and maintenance release, refer to the table below.

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 when you boot up your switch with the new image for the first time.

  • 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.

Software Installation Commands

Summary of Software Installation Commands

Supported starting from Cisco IOS XE Everest 16.6.2 and later releases

To install and activate the specified file, and to commit changes to be persistent across reloads:

install add file filename [ activate commit]

To separately install, activate, commit, cancel, or remove the installation file: install ?

add file tftp: filename

Copies the install file package from a remote location to the device and performs a compatibility check for the platform and image versions.

activate [ auto-abort-timer]

Activates the file, and reloads the device. The auto-abort-timer keyword automatically rolls back image activation.

commit

Makes changes persistent over reloads.

rollback to committed

Rolls back the update to the last committed version.

abort

Cancels file activation, and rolls back to the version that was running before the current installation procedure started.

remove

Deletes all unused and inactive software installation files.


Note

The request platform software commands are deprecated starting from Cisco IOS XE Gibraltar 16.10.1. The commands are visible on the CLI in this release and you can configure them, but we recommend that you use the install commands to upgrade or downgrade.

Summary of request platform software Commands

Device# request platform software package ?

clean

Cleans unnecessary package files from media

copy

Copies package to media

describe

Describes package content

expand

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 Bengaluru 17.4.x

Cisco IOS XE Everest 16.6.2 and all later releases

Either install commands or request platform software commands5.

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

The sample output in this section displays upgrade from Cisco IOS XE Amsterdam 17.3.1 to Cisco IOS XE Bengaluru 17.4.1 using install commands only.

Procedure


Step 1

Clean-up

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.
    Switch# copy tftp://10.8.0.6/image/cat9k_iosxe.17.04.01.SPA.bin flash:
    destination filename [cat9k_iosxe.17.04.01.SPA.bin]?

    601216545 bytes copied in 50.649 secs (11870255 bytes/sec)
    
     
  2. dir flash:

    Use this command to confirm that the image has been successfully copied to flash.
    Switch# dir flash:*.bin
    Directory of flash:/*.bin
     
    Directory of flash:/
     
    434184 -rw- 601216545    Nov 16 2020 10:18:11 -07:00 cat9k_iosxe.17.04.01.SPA.bin
    11353194496 bytes total (8976625664 bytes free)
    
    
Step 3

Set boot variable

  1. boot system flash:packages.conf

    Use this command to set the boot variable to flash:packages.conf .
    Switch(config)# boot system flash:packages.conf
    
  2. no boot manual

    Use this command to configure the switch to auto-boot.
    Switch(config)# no boot manual
    Switch(config)# exit
  3. write memory

    Use this command to save boot settings.
    Switch# write memory
  4. show boot

    Use this command to verify the boot variable (packages.conf) and manual boot setting (no):
    Switch# show boot            
    Current Boot Variables:
    BOOT variable = flash:packages.conf;
    
    Boot Variables on next reload:
    BOOT variable = flash:packages.conf;
    Manual Boot = no
    Enable Break = yes
    Boot Mode = DEVICE
    iPXE Timeout = 0 
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.17.04.01.SPA.bin activate commit.

The following sample output displays installation of the Cisco IOS XE Bengaluru 17.4.1 software image in the flash memory:
Switch# install add file flash:cat9k_iosxe.17.04.01.SPA.bin activate commit

Step 6

Upgrade the ROMMON version

upgrade rom-monitor capsule golden switch
A new ROMMON version is available in Cisco IOS XE Bengaluru 17.4.1, for only the C9300 models in the series. After you enter the command, confirm upgrade at the system prompt.
Switch# upgrade rom-monitor capsule golden switch active R0 
This operation will reload the switch and take a few minutes to complete. Do you want to proceed (y/n)? [confirm]y
Switch#
Initializing Hardware...
<output truncated>

For more information about this, see ROMMON Upgrades in this document.

Step 7

Reload and verify version

  1. reload

    Use this command to reload the switch. When the switch reloads after a ROMMON upgrade, the ROMMON version is updated, but not displayed in the output until the next reload.
    Switch# reload
  2. show version

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

    The following sample output of the show version command displays the Cisco IOS XE Bengaluru 17.4.1 image on the device:
    Switch# show version
    Cisco IOS XE Software, Version 17.04.01
    Cisco IOS Software [Bengaluru], Catalyst L3 Switch Software (CAT9K_IOSXE), Version 17.4.1, RELEASE SOFTWARE (fc1)

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 Bengaluru 17.4.1

Either install commands or request platform software command6.

Cisco IOS XE Amsterdam 17.3.1 or earlier releases.

6 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.

The sample output in this section shows downgrade from Cisco IOS XE Bengaluru 17.4.1 to Cisco IOS XE Amsterdam 17.3.1, using install commands.

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.

The following sample output displays the cleaning up of unused files, by using the install remove inactive command:
Switch# install remove inactive
 
install_remove: START Mon Nov 16 19:51:48 PDT 2020

SUCCESS: install_remove  Mon Nov 16 11:42:39 PDT 2020

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.
    Switch# copy tftp://10.8.0.6/image/cat9k_iosxe.17.03.01.SPA.bin flash:
    Destination filename [cat9k_iosxe.17.03.01.SPA.bin]?
    Accessing tftp://10.8.0.6//cat9k_iosxe.17.03.01.SPA.bin...
    Loading /cat9k_iosxe.17.03.01.SPA.bin from 10.8.0.6 (via GigabitEthernet0/0): 
    !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    [OK - 508584771 bytes]
    508584771 bytes copied in 101.005 secs (5035244 bytes/sec)
     
    
  2. dir flash:

    Use this command to confirm that the image has been successfully copied to flash.
    Switch# dir flash:*.bin
    Directory of flash:/*.bin
     
    Directory of flash:/
     
    434184 -rw- 508584771 Nov 16 2020 13:35:16 -07:00 cat9k_iosxe.17.03.01.SPA.bin
    11353194496 bytes total (9055866880 bytes free)
    
    
Step 3

Set boot variable

  1. boot system flash:packages.conf

    Use this command to set the boot variable to flash:packages.conf .
    Switch(config)# boot system flash:packages.conf
    
  2. no boot manual

    Use this command to configure the switch to auto-boot.
    Switch(config)# no boot manual
    Switch(config)# exit
  3. write memory

    Use this command to save boot settings.
    Switch# write memory
  4. show boot

    Use this command to verify the boot variable (packages.conf) and manual boot setting (no):
    Switch# show boot            
    Current Boot Variables:
    BOOT variable = flash:packages.conf;
    
    Boot Variables on next reload:
    BOOT variable = flash:packages.conf;
    Manual Boot = no
    Enable Break = yes
    Boot Mode = DEVICE
    iPXE Timeout = 0 
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.17.03.01.SPA.bin activate commit.

The following example displays the installation of the Cisco IOS XE Amsterdam 17.3.1 software image to flash, by using the install add file activate commit command.
Switch# install add file flash:cat9k_iosxe.17.03.01.SPA.bin activate commit

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.

There is no FPGA upgrade in Cisco IOS XE Bengaluru 17.4.1. 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.


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.

Available Licensing Models and Configuration Information

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

    In the software configuration guide of the required release, see System ManagementConfiguring 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 ManagementSmart Licensing Using Policy.

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

License Levels - Usage Guidelines

  • 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:

    Table 3. Permitted Combinations

    DNA Essentials

    DNA Advantage

    Network Essentials

    Yes

    No

    Network Advantage

    Yes7

    Yes

    7 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.

Limitations and Restrictions

  • 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.

  • Cisco TrustSec restrictions—Cisco TrustSec can be configured only on physical interfaces, not on logical interfaces.

  • 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 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.

  • 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.

    • Only homogenous stacking is supported, mixed stacking is not.

      C9300 SKUs can be stacked only with other C9300 SKUs. Similarly C9300L SKUs can be stacked only with other C9300L SKUs.

      The following 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
  • 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.
