Smart Licensing Using Policy Factory-installed trust code Support for trust code in additional topologies Ability to save authorization code request and return in a file and simpler upload in the CSSM Web UI RUM Report optimization and availability of statistics Support to collect software version in a RUM report Account information included in the ACK and show command outputs CSLU support for Linux	The following Smart Licensing Using Policy enhancements were introduced in this release: Factory-installed trust code: For new hardware orders, a trust code is now installed at the time of manufacturing. Note: You cannot use a factory-installed trust code to communicate with CSSM. See: Overview and Trust Code. Support for trust code in additional topologies: A trust code is automatically obtained in topologies where the product instance initiates the sending of data to CSLU and in topologies where the product instance is in an air-gapped network. See: Trust Code Connected to CSSM Through CSLU and Tasks for Product Instance-Initiated Communication CSLU Disconnected from CSSM and Tasks for Product Instance-Initiated Communication No Connectivity to CSSM and No CSLU and Workflow for Topology: No Connectivity to CSSM and No CSLU Ability to save authorization code request and return in a file and simpler upload in the CSSM Web UI: If your product instance is in an air-gapped network, you can now save a SLAC request in a file on the product instance. The SLAC request file must be uploaded to the CSSM Web UI. You can then download the file containing the SLAC code and install it on the product instance. You can also upload a return request file in a similar manner. With this new method you do not have to gather and enter the required details on the CSSM Web UI to generate a SLAC. You also do not have to locate the product instance in the CSSM Web UI to return an authorization code. In the CSSM Web UI, the request or return file is uploaded in the same location and in the same way as you upload a RUM report. In the required Smart Account, navigate to Reports → Usage Data Files. See: No Connectivity to CSSM and No CSLU, Workflow for Topology: No Connectivity to CSSM and No CSLU, and license smart (privileged EXEC). RUM Report optimization and availability of statistics: RUM report generation and related processes have been optimized. This includes a reduction in the time it takes to process RUM reports, better memory and disk space utilization, and visibility into the RUM reports on the product instance (how many there are, the processing state each one is in, if there are errors in any of them, and so on). See: RUM Report and Report Acknowledgement, Upgrades Within the Smart Licensing Using Policy Environment, and Downgrades Within the Smart Licensing Using Policy Environment. Also see: show license rum, show license tech, and show license all. Support to collect software version in a RUM report: If version privacy is disabled (no license smart privacy version global configuration command), the Cisco IOS-XE software version running on the product instance and the Smart Agent version information is included in the RUM report. See: license smart (global config). Account information included in the ACK and show command outputs: A RUM acknowledgement (ACK) includes the Smart Account and Virtual Account that was reported to, in CSSM. You can then display account information using various show commands. The account information that is displayed is always as per the latest available ACK on the product instance. See: show license status, show license summary, show license all, and show license tech. CSLU support for Linux: CSLU can now be deployed on a machine (laptop or desktop) running Linux. See: CSLU, Workflow for Topology: Connected to CSSM Through CSLU and Workflow for Topology: CSLU Disconnected from CSSM.
Switch Integrated Security Features (SISF): ARP Protection	Support for the prevention of IPv4 spoofing was introduced (Detection and reporting of IPv4 spoofing is supported since the introductory release of SISF). See: Example: Detecting and Preventing Spoofing.
New on the WebUI
There are no WebUI features in this release.
Serviceability
access-session host-mode multi-host peer	The command was modified. peer keyword was introduced. Use this command to enable authentication and authorization of a device before any other devices on the fabric edge port. Ensure that the extended node is the peer device that is connected to the fabric edge port.
show ip pim vrf	The command was introduced. It displays Protocol Independent Multicast (PIM) related information for all VRFs.
show ip mroute vrf	The command was introduced. It displays all the multicast VPN routing and forwarding (VRF) instances related to multicast routing tables.
show consistency-checker mcast l3m	The command was modified. mcast l3m keyword was introduced. It displays inconsistent states of software entries on the Layer 3 multicast forwarding tables.

Accessing Hidden Commands

This section provides information about hidden commands in Cisco IOS XE and the security measures that are in place, when they are accessed. These commands are only meant to assist Cisco TAC in advanced troubleshooting and are not documented.

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.

Default Behaviour

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).

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.

Software Images


Release	Image Type	File Name
Cisco IOS XE Cupertino 17.7.1	CAT9K_LITE_IOSXE	cat9k_lite_iosxe.17.07.01.SPA.bin

Automatic Boot Loader Upgrade

When you upgrade from the existing release on your switch to a later or newer release for the first time, the boot loader may be automatically upgraded, based on the hardware version of the switch. If the boot loader is automatically upgraded, it will take effect on the next reload. If you go back to the older release after this, the boot loader is not downgraded. The updated boot loader supports all previous releases.

Caution

Do not power cycle your switch during the upgrade.

Software Installation Commands


Summary of Software Installation Commands
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.

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 ...	To...
Cisco IOS XE Bengaluru 17.6.x or earlier releases	Cisco IOS XE Cupertino 17.7.x

The sample output in this section displays upgrade from Cisco IOS XE Bengaluru 17.6.1 to Cisco IOS XE Cupertino 17.7.1 using install commands only.

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:

Note

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

Step 5

Verify installation

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

dir flash:*.pkg

The following is sample output of the dir flash:*.pkg command:

Switch# dir flash:*.pkg

dir flash:*.conf
The following is sample output of the dir flash:*.conf command. It displays the .conf files in the flash partition; note the two .conf files:
- packages.conf—the file that has been re-written with the newly installed .pkg files
- cat9k_lite_iosxe.17.07.01.SPA.conf— a backup copy of the newly installed packages.conf file
```
Switch# dir flash:*.conf
 
Directory of flash:/*.conf

```

Step 6

Reload and verify version

reload
Use this command to reload the switch. When you boot the new image, the boot loader is automatically updated, but the new bootloader version is 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 Cupertino 17.7.1 image on the device:

Switch# show version

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 ...	To ...
Cisco IOS XE Bengaluru 17.6.x	Cisco IOS XE Bengaluru 17.5.x or earlier releases.

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 17.6.1 to Cisco IOS XE Bengaluru 17.5.1, using install commands.

Procedure

Step 1

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 9200 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 Fuji 16.9.2 to Cisco IOS XE Amsterdam 17.3.1: Smart Licensing is the default and the only supported method to manage licenses.

In the software configuration guide of the required release, see System Management → Configuring Smart Licensing.
Cisco IOS XE Amsterdam 17.3.2a and later: Smart Licensing Using Policy, which is an enhanced version of Smart Licensing, is the default and the only supported method to manage licenses.

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

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

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 1. Permitted Combinations
	DNA Essentials	DNA Advantage
Network Essentials	Yes	No
Network Advantage	Yes⁵	Yes

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

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

Scaling Guidelines

For information about feature scaling guidelines, see the Cisco Catalyst 9200 Series Switches datasheet at:

https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-9200-series-switches/nb-06-cat9200-ser-data-sheet-cte-en.html

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.
Hardware limitations
- Management Port—You cannot modify the configured port speed, duplex mode and flow control and disable auto-negotiation on the Ethernet Management port (GigabitEthernet0/0). Port speed and duplex mode can only be changed from a peer port.
- Network Module — When the C9200-NM-4X network module is plugged into the C9200 SKUs of the Cisco Catalyst 9200 Series Switches, the uplink interface remains in down state until the network module is recognized by the switch. The time taken for the switch to recognize the network module is longer in comparison to the time taken by the switch to recognize other interconnected devices.
- If the 1-meter and 1.5-meter 10-GBase-CX1 cables, which are connected on the 10-G ports of the Catalyst 9200L switches, are connected to the 10-G peer ports of the Catalyst 9200L or Catalyst 9200 switches, the peer device might go into the error-disabled state because of link flapping if the local device is restarted. As a workaround, run the shut and no shut commands on the error-disabled peer interfaces.
QoS restrictions
- When configuring QoS queuing policy, the sum of the queuing buffer should not exceed 100%.
- Policing and marking policy on sub interfaces is supported.
- Marking policy on switched virtual interfaces (SVI) is supported.
- QoS policies are not supported for port-channel interfaces, tunnel interfaces, and other logical interfaces.
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).
Stacking
- Stacking is supported on Cisco Catalyst 9200 Series Switches. A switch stack supports up to eight stack members. However, you cannot stack C9200 SKUs with C9200L SKUs
  
  The supported stacking bandwidth on C9200L SKUs is up to 80Gbps; on C9200 SKUs, this is up to 160Gbps.
- The C9200-24PB and C9200-48PB switch models can be stacked only with each other and not with other models of the Cisco Catalyst 9200 Series Switches.
- 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
```
MACsec is not supported on Software-Defined Access deployments.
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.
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.
Upgrading the software image from Cisco IOS XE Gibraltar 16.12.x to any of the later releases can result in a persistent database operation failure and after which the persistent database cannot be restored.

To avoid the persistent database operation failure, use the dir bootflash:.dbpersist command to list all DB persist files and then use delete bootflash:/.dbpersist/folder_name/file_name and bootflash:/.dbpersist/folder_name/file_name.meta commands to delete individual database and meta files from each persistent database folder.
The File System Check (fsck) utility is not supported in install mode.
The DiagMemoryTest GOLD test is not supported on the Catalyst 9200 Series Switches.

Caveats

Caveats describe unexpected behavior in Cisco IOS-XE releases. Caveats listed as open in a prior release are carried forward to the next release as either open or resolved.

Cisco Bug Search Tool

The Cisco Bug Search Tool (BST) allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data such as bug details, product, and version.
