Feature Name	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. (A license level does not apply)
MLDP-Based MVPN	The MLDP-based MVPN feature provides extensions to Label Distribution Protocol (LDP) for the setup of point-to-multipoint (P2MP) and multipoint-to-multipoint (MP2MP) label switched paths (LSPs) for transport in the Multicast Virtual Private Network (MVPN) core network. See IP Multicast Routing Configuration Guide → MLDP-Based MVPN. (Network Advantage)

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 Behaviour—All Models

Beginning from Cisco IOS XE Gibraltar 16.12.5 and later, do not fragment bit (DF bit) in the IP packet is always set to 0 for all outgoing RADIUS packets (packets that originate from the device towards the RADIUS server).

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

Cisco Catalyst 9500 Series Switches—Model Numbers

The following table lists the supported hardware models and the default license levels they are delivered with. For more information about the available license levels, see section License Levels.

Base PIDs are the model numbers of the switch.

Bundled PIDs indicate the orderable part numbers for base PIDs that are bundled with a particular network module. Entering the show version , show module , or show inventory commands on such a switch (bundled PID), displays its base PID.

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.

The following table provides ROMMON version information for the Cisco Catalyst 9500 Series Switches. For ROMMON version information of Cisco IOS XE 16.x.x releases, refer to the corresponding Cisco IOS XE 16.x.x release notes of the respective platform.

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.

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

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.

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.

Step 2

Copy new image to flash

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:

11353194496 bytes total (8976625664 bytes free)

Step 3

Set boot variable

boot system flash:packages.conf
Use this command to set the boot variable to flash:packages.conf .
```
Switch(config)# boot system flash:packages.conf
```
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
```
write memory
Use this command to save boot settings.
```
Switch# write memory
```

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

For more information about this, see Upgrading the ROMMON in this document.

Step 7

Reload and verify version

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
```

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 Amsterdam 17.3.1 image on the device:

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

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:

11353194496 bytes total (9055866880 bytes free)

Step 3

Set boot variable

boot system flash:packages.conf
Use this command to set the boot variable to flash:packages.conf .
```
Switch(config)# boot system flash:packages.conf
```
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
```
write memory
Use this command to save boot settings.
```
Switch# write memory
```

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.

In Service Software Upgrade (ISSU) with Cisco StackWise Virtual

Follow the instructions described here to perform an In Service Software Upgrade (ISSU) upgrade. Use the procedure described here, only for the releases indicated in the table below. For more general information about ISSU release support and recommended releases, see this technical reference document: In-Service Software Upgrade (ISSU).

Before you begin

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


When upgrading from...	Use these commands...	To...
Cisco IOS XE Amsterdam 17.3.1	install add file activate issu commit	Cisco IOS XE Amsterdam 17.3.x
Not applicable	ISSU does not support downgrade. To downgrade, see Downgrading in Install Mode.	Not applicable

Procedure

Step 1	enable Enables privileged EXEC mode. Enter your password if prompted. `Switch# enable`
Step 2	show version \| in INSTALL or show version \| in System image On the Catalyst 9500 Series Switches, use show version \| in INSTALL command to check the boot mode. ISSU is supported only in install mode. You cannot perform ISSU if the switch is booted in bundle mode. `Switch# show version \| in INSTALL Switch Ports Model SW Version SW Image Mode ------ ----- ----- ---------- ---------- ---- * 1 12 C9500-12Q 17.3.1 CAT9K_IOSXE INSTALL 2 12 C9500-12Q 17.3.1 CAT9K_IOSXE INSTALL` On Catalyst 9500 Series Switches - High Performance, use show version \| in System image to check if the switch booted into IOS via “ boot flash:packages.conf ”. The output should display the following: `Switch# show version \| in System image System image file is "flash:packages.conf"` You cannot perform ISSU if the switch is booted in bundle mode. If you perform ISSU in bundle mode, you will see the following error. `*Nov 10 14:55:57.338: %INSTALL-5-INSTALL_START_INFO: Chassis 1 R1/0: install_engine: Started install one-shot ISSU flash:cat9k_iosxe.17.3.02.SPA.bininstall_add_activate_commit: Adding ISSU ERROR: install_add_activate_commit: One-Shot ISSU operation is not supported in bundle boot mode FAILED: install_add_activate_commit exit(1) Tue Nov 10 14:56:03 UTC 2020`
Step 3	dir flash: \| in free Use this command to check if there is sufficient available memory on flash. Ensure that you have at least 1GB of space in flash to expand a new image. `Switch# dir flash: \| in free 11353194496 bytes total (8565174272 bytes free)`
Step 4	show redundancy Use this command to check if the switch is in SSO mode. `Switch# show redundancy Redundant System Information : ------------------------------ Available system uptime = 4 minutes Switchovers system experienced = 0 Standby failures = 0 Last switchover reason = none Hardware Mode = Duplex Configured Redundancy Mode = sso Operating Redundancy Mode = sso Maintenance Mode = Disabled Communications = Up <output truncated>`
Step 5	show boot system Use this command to verify that the manual boot variable is set to no . `Switch# show boot system Current Boot Variables: BOOT variable = flash:packages.conf; MANUAL_BOOT variable = no Boot Variables on next reload: BOOT variable = flash:packages.conf; MANUAL_BOOT variable = no Enable Break = no Boot Mode = DEVICE iPXE Timeout = 0` If the manual boot variable is set to yes , use the no boot manual command in global configuration mode to set the switch for autoboot.
Step 6	show issu state [`detail`] Use this command to verify that no other ISSU process is in progress. `Switch# show issu state detail --- Starting local lock acquisition on chassis 2 --- Finished local lock acquisition on chassis 2 No ISSU operation is in progress Switch#`
Step 7	show install summary Use this command to verify that the state of the image is Activated & Committed. Clear the install state if the state is not Activated & Committed. `Switch# show install summary [ Switch 1 2 ] Installed Package(s) Information: State (St): I - Inactive, U - Activated & Uncommitted, C - Activated & Committed, D - Deactivated & Uncommitted -------------------------------------------------------------------------------- Type St Filename/Version -------------------------------------------------------------------------------- IMG C 17.3.2.0.2433`
Step 8	install add file activate issu commit Use this command to automate the sequence of all the upgrade procedures, including downloading the images to both the switches, expanding the images into packages, and upgrading each switch as per the procedures. `Switch# install add file tftp:cat9k_iosxe.17.3.02.SPA.bin activate issu commit` The following sample output displays installation of Cisco IOS XE Amsterdam 17.3.2a software image with ISSU procedure.

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. The version is not downgraded when you downgrade the software image.

On the Cisco Catalyst 9500 Series Switches-High Performance, it is from Cisco IOS XE Fuji 16.8.1a to Cisco IOS XE Amsterdam 17.3.1.

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.

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.

Scaling Guidelines

For information about feature scaling guidelines, see the Cisco Catalyst 9500 Series Switches datasheet at:

https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-9500-series-switches/datasheet-c78-738978.html

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 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.
- 1G with Cisco QSA Module (CVR-QSFP-SFP10G) is not supported on the uplink ports of the C9500-24Y4C and C9500-48Y4C models.
- 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.
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).
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
```
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.
HTTP Services Restriction—If you configure ip http active-session-modules none and ip http secure-active-session-modules none commands, NGINX process will be held down. This will prevent HTTP or HTTPS from running. Use the ip http session-module-list command to enable the required HTTP modules.
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.
The File System Check (fsck) utility is not supported in install mode.
