Description, Documentation Link, and License Level Information

Smart Software Manager On-Prem (SSM On-Prem) Support for Smart Licensing Using Policy

SSM On-Prem is an asset manager, which works in conjunction with CSSM. It enables you to administer products and licenses on your premises instead of having to directly connect to CSSM.

Here, a product instance is connected to SSM On-Prem, and SSM On-Prem becomes the single point of interface with CSSM. The product instance can be configured to push the required information to SSM On-Prem. Alternatively, SSM On-Prem can be set-up to pull the required information from a product instance at a configurable frequency. After usage information is available in SSM On-Prem, you must synchronize the same with CSSM, to ensure that the product instance count, license count and license usage information is the same on both, CSSM and SSM On‐Prem. Offline and online options are available for synchronization between CSSM and SSM On‐Prem.

Minimum Required SSM On-Prem Version: Version 8, Release 202102.

Minimum Required Cisco IOS XE Version: Cisco IOS XE Amsterdam 17.3.3.

See System Mangement → Smart Licensing Using Policy and System Management Commands.

Software Features Introduced on All Models

Feature Name

Description, Documentation Link, and License Level Information

Smart Licensing Using Policy

An enhanced version of Smart Licensing, with the overarching objective of providing a licensing solution that does not interrupt the operations of your network, rather, one that enables a compliance relationship to account for the hardware and software licenses you purchase and use.

With this licensing model, you do not have to complete any licensing-specific operations, such as registering or generating keys before you start using the software and the licenses that are tied to it. License usage is recorded on your device with timestamps and the required workflows can be completed at a later date.

Multiple options are available for license usage reporting – this depends on the topology you implement. You can use the Cisco Smart Licensing Utility (CSLU) Windows application, or report usage information directly to CSSM. A provision for offline reporting for air-gapped networks, where you download usage information and upload to CSSM, is also available.

Starting with this release, Smart Licensing Using Policy is automatically enabled on the device. This is also the case when you upgrade to this release.

By default, your Smart Account and Virtual Account in CSSM is enabled for Smart Licensing Using Policy.

For conceptual, configuration, migration, and troubleshooting information for Smart Licensing Using Policy, see the documentation links below.

See System Mangement → Smart Licensing Using Policy and System Management Commands.

(A license level does not apply)

Cisco DNA Center Support for Smart Licensing Using Policy

Cisco DNA Center supports Smart Licensing Using Policy functionality starting with Cisco DNA Center Release 2.2.2. The corresponding minimum required Cisco IOS XE Release on the Cisco Catalyst 9500 Series Switches (all models) is Cisco IOS XE Amsterdam 17.3.2a.

Implement the “Connected to CSSM Through a Controller” topology to have Cisco DNA Center manage a product instance. When you do, the product instance records license usage, but it is the Cisco DNA Center that initiates communication with the product instance to retrieve and report usage to Cisco Smart Software Manager (CSSM), and returns the acknowledgement (RUM ACK).

In order to meet reporting requirements, Cisco DNA Center provides ad hoc or on-demand reporting, as well as scheduled reporting options.

See System Mangement → Smart Licensing Using Policy.

Accessing Hidden Commands

From 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. Hidden commands are only meant to assist Cisco TAC in advanced troubleshooting, and are not documented either.

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

  • Category 1: Hidden commands in Privileged or User EXEC mode. Enter the service internal command to access these commands.

  • Category 2: Hidden commands in one of the configuration modes (global, interface, and so on).

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

  • The commands have CLI help. 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. The following is an 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 categories 1 and 2, there are other internal commands displayed on the CLI, for which the system does not generate the %PARSER-5-HIDDEN syslog message.


Note

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

If you find that you need to use 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 nonhidden commands.


Default Interface Behaviour on Cisco Catalyst 9500 Series Switches - High Performance Only

From Cisco IOS XE Gibraltar 16.11.1, the default interface for all High Performance models in the series changes from Layer 3 to Layer 2. Use the no switchport command to change the Layer 2 interface into Layer 3 mode.

The startup configuration has explicit configuration of the switchport command for Layer 2 interfaces and the no switchport command for Layer 3 interfaces to address this change in behaviour and to support seamless migration.

Supported Hardware

Upgrading 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.

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

    On the C9500-12Q, C9500-16X, C9500-24Q, C9500-40X models of the series, you must manually upgrade the ROMMON in the primary SPI flash device, if a new version is applicable, and the release you are upgrading from is Cisco IOS XE Gibraltar 16.12.1 or a later release. (So if you upgrade from Cisco IOS XE Gibraltar 16.11.1 for example, a manual upgrade does not apply; the ROMMON is automatically updated, if applicable). Enter the upgrade rom-monitor capsule primary switch command in privileged EXEC mode.

    On the C9500-24Y4C, C9500-32C, C9500-32QC, and C9500-48Y4C models of the series, 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. The manual upgrade applies to all models in the series. Enter the upgrade rom-monitor capsule golden switch command in privileged EXEC mode.


Note

In case of a Cisco StackWise Virtual setup, upgrade the active and standby switch.


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.

    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. Settings are synchronized with the standby switch, if applicable.
    Switch(config)# no boot manual
    Switch(config)# exit
  3. write memory

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

    Use this command to verify the boot variable (packages.conf) and manual boot setting (no):
    Switch# show bootvar               <<on the C9500-24Y4C,C9500-32C, C9500-32QC, and C9500-48Y4C models
    BOOT variable = bootflash:packages.conf
    MANUAL_BOOT variable = no
    BAUD variable = 9600
    ENABLE_BREAK variable = yes
    BOOTMODE variable does not exist
    IPXE_TIMEOUT variable does not exist
    CONFIG_FILE variable = 
    
    Standby BOOT variable = bootflash:packages.conf
    Standby MANUAL_BOOT variable = no
    Standby BAUD variable = 9600
    Standby ENABLE_BREAK variable = yes
    Standby BOOTMODE variable does not exist
    Standby IPXE_TIMEOUT variable does not exist
    Standby CONFIG_FILE variable = 
    Switch# show boot                        <<on the C9500-12Q,C9500-16X C9500-24Q, and C9500-40X models
    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.17.03.01.SPA.bin activate commit.

The following sample output displays installation of the Cisco IOS XE Amsterdam 17.3.1 software image in the flash memory:
Switch# install add file flash:cat9k_iosxe.17.03.01.SPA.bin activate commit

Downgrading in Install Mode

Follow these instructions to downgrade from one release to another, in install mode.

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 Amsterdam 17.3.x

  • On Cisco Catalyst 9500 Series Switches, either install commands or request platform software commands7.

  • On Cisco Catalyst 9500 Series Switches - High Performance, only install commands

Cisco IOS XE Amsterdam 17.2.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.

Use the procedure described here to downgrade the device in the following configurations:

  • Standalone

  • Cisco StackWise Virtual

  • Cisco StackWise Virtual without ISSU

The sample output in this section shows downgrade from Cisco IOS XE Amsterdam 17.3.1 to Cisco IOS XE Amsterdam 17.2.1, using install commands.

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

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.17.02.01.SPA.bin flash:
    Destination filename [cat9k_iosxe.17.02.01.SPA.bin]?

    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 Jul 15 2020 13:35:16 -07:00 cat9k_iosxe.17.02.01.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. Settings are synchronized with the standby switch, if applicable.
    Switch(config)# no boot manual
    Switch(config)# exit
  3. write memory

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

    Use this command to verify the boot variable (packages.conf) and manual boot setting (no):
    Switch# show bootvar               <<on the C9500-24Y4C,C9500-32C, C9500-32QC, and C9500-48Y4C models
    BOOT variable = bootflash:packages.conf
    MANUAL_BOOT variable = no
    BAUD variable = 9600
    ENABLE_BREAK variable = yes
    BOOTMODE variable does not exist
    IPXE_TIMEOUT variable does not exist
    CONFIG_FILE variable = 
    
    Standby BOOT variable = bootflash:packages.conf
    Standby MANUAL_BOOT variable = no
    Standby BAUD variable = 9600
    Standby ENABLE_BREAK variable = yes
    Standby BOOTMODE variable does not exist
    Standby IPXE_TIMEOUT variable does not exist
    Standby CONFIG_FILE variable = 
    Switch# show boot                        <<on the C9500-12Q,C9500-16X C9500-24Q, and C9500-40X models
    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 17.2.1 software image to flash, by using the install add file activate commit command.
Switch# install add file flash:cat9k_iosxe.17.02.01.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 Amsterdam 17.3.1, Cisco IOS XE Amsterdam 17.3.2a, Cisco IOS XE Amsterdam 17.3.3, and Cisco IOS XE Amsterdam 17.3.4. 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 9500 Series Switches and Cisco Catalyst 9500 Series Switches - High Performance 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

    Yes8

    Yes

    8 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

With Cisco Catalyst 9500 Series Switches and Cisco Catalyst 9500 Series Switches - High Performance—If a feature is not supported on a switch model, you do not have to factor in any limitations or restrictons that may be listed here. If limitations or restrictions are listed for a feature that is supported, check if model numbers are specified, to know if they apply. If model numbers are not specified, the limitations or restrictons apply to all models in the series.

  • Auto negotiation

    Auto negotiation (the speed auto command) and half duplex (the duplex half command) are not supported on GLC-T or GLC-TE transceivers for 10 Mbps and 100 Mbps speeds. This applies only to the C9500-48Y4C and C9500-24Y4C models of the series.

    We recommend not changing Forward Error Correction (FEC) when auto negotiation is ON. This is applicable to 100G/40G/25G CU cables on the C9500-32C, C9500-32QC, C9500-24Y4C and C9500-48Y4C models of the series.

  • 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 StackWise Virtual

    • On Cisco Catalyst 9500 Series Switches, when Cisco StackWise Virtual is configured, breakout ports using 4X10G breakout cables, or the Cisco QSFP to SFP or SFP+ Adapter (QSA) module can only be used as data ports; they cannot be used to configure StackWise Virtual links (SVLs) or dual-active detective (DAD) links.

    • On Cisco Catalyst 9500 Series Switches - High Performance,

      • When Cisco StackWise Virtual is configured, breakout ports using 4X25G or 4X10G breakout cables, or the Cisco QSA module can only be used as data ports; they cannot be used to configure SVLs or DAD links.

      • When Cisco StackWise Virtual is configured, Cisco QSA module with 10G SFP modules can be used as data ports and to configure SVLs or DAD links.

      • When Cisco StackWise Virtual is configured, Cisco QSA module with 1G SFP modules can be used as data ports and to configure DAD links; they cannot be used to configure SVLs since SVLs are not supported on 1G interfaces.

  • 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.

  • Hardware limitations:

    • Use the MODE button to switch-off the beacon LED.

    • All port LED behavior is undefined until interfaces are fully initialized.

    • The following limitations apply to Cisco QSA Module (CVR-QSFP-SFP10G) when Cisco 1000Base-T Copper SFP (GLC-T) or Cisco 1G Fiber SFP Module for Multimode Fiber are plugged into the QSA module:

      • 1G Fiber modules over QSA do not support autonegotiation. Auto-negotiation should be disabled on the far-end devices.

      • Although visible in the CLI, the command [no] speed nonegotiate is not supported with 1G Fiber modules over QSA.

      • Only GLC-T over QSA supports auto-negotiation.

      • GLC-T supports only port speed of 1000 Mb/s over QSA. Port speeds of 10/100-Mb/s are not supported due to hardware limitation.

    • When you use Cisco QSFP-4SFP10G-CUxM Direct-Attach Copper Cables, autonegotiation is enabled by default. If the other end of the line does not support autonegotation, the link does not come up.

    • Autonegotiation is not supported on HundredGigabitEthernet1/0/49 to HundredGigabitEthernet1/0/52 uplink ports of the C9500-48Y4C models, and HundredGigabitEthernet1/0/25 to HundredGigabitEthernet1/0/28 uplink ports of the C9500-24Y4C models. Disable autonegotiation on the peer device if you are using QSFP-H40G-CUxx and QSFP-H40G-ACUxx cables.

    • For QSFP-H100G-CUxx cables, the C9500-48Y4C and C9500-24Y4C models support the cables only if both sides of the connection are either C9500-48Y4C or C9500-24Y4C.

  • Interoperability limitations—When you use Cisco QSFP-4SFP10G-CUxM Direct-Attach Copper Cables, if one end of the 40G link is a Catalyst 9400 Series Switch and the other end is a Catalyst 9500 Series Switch, the link does not come up, or comes up on one side and stays down on the other. To avoid this interoperability issue between devices, apply the the speed nonegotiate command on the Catalyst 9500 Series Switch interface. This command disables autonegotiation and brings the link up. To restore autonegotiation, use the no speed nonegotiation command.

  • In-Service Software Upgrade (ISSU)

    • In-Service Software Upgrade (ISSU)—On Cisco Catalyst 9500 Series Switches (C9500-12Q, C9500-16X, C9500-24Q, C9500-40X), ISSU from Cisco IOS XE Fuji 16.9.x to Cisco IOS XE Gibraltar 16.10.x or to Cisco IOS XE Gibraltar 16.11.x is not supported.

    • On Cisco Catalyst 9500 Series Switches - High Performance (C9500-24Y4C, C9500-32C, C9500-32QC, and C9500-48Y4C), ISSU with Cisco StackWise Virtual is supported only starting from Cisco IOS XE Gibraltar 16.12.1. Therefore, ISSU upgrades can be performed only starting from this release to a later release.

    • While ISSU allows you to perform upgrades with zero downtime, we recommend you to do so during a maintenance window only.

    • If a new feature introduced in a software release requires a change in configuration, the feature should not be enabled during ISSU.

    • If a feature is not available in the downgraded version of a software image, the feature should be disabled before initiating ISSU.

  • 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.

  • 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.

  • 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 500 connections per second (CPS) at less than 50% CPU utilization. Above this rate, AVC service is not guaranteed.

    • Scale—Able to handle up to 5000 bi-directional flows per 24 access ports and 10000 bi-directional flows 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.
