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.

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 Licening Using Policy and System Management Commands.

ThousandEyes Enterprise Agent

A new version of the ThousandEyes Enterprise Agent is introduced. This is an embedded Docker-based application that runs on Cisco devices using the application-hosting capability.The Enterprise Agent is available on both the SSD and bootflash.

See Programmability Configuration Guide → Application Hosting.

(Network Advantage)

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.

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 Licening 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 9300 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 Licening Using Policy.

(A license level does not apply)

Extended Fast Software Upgrade

Extended Fast Software Upgrade reduces the traffic downtime to less than 30 seconds during software reload operations.

See System Management → Extended Fast Software Upgrade.

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.

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).

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.

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

- Software Images

- Upgrading the ROMMON

- Software Installation Commands

- Upgrading in Install Mode

- Downgrading in Install Mode

- Field-Programmable Gate Array Version Upgrade

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

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

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.17.03.01.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:

For more information about this, see Upgrading the ROMMON 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 Amsterdam 17.3.1 image on the device:

Switch# show version
Cisco IOS XE Software, Version 17.03.01

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 Amsterdam 17.3.x

Either install commands or request platform software command[1].

Cisco IOS XE Amsterdam 17.2.x or earlier releases.

[1] 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 Amsterdam 17.3.1 to Cisco IOS XE Amsterdam 17.2.1, 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

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 20 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.

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 17.2.1 software image to flash, by using the install add file activate commit command.

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.

Licensing

This section provides information about the licensing packages for features available on Cisco Catalyst 9000 Series Switches.

- License Levels

- Available Licensing Models and Configuration Information

- License Levels - Usage Guidelines

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 Fuji 16.8.x and earlier: RTU Licensing is the default and the only supported method to manage licenses.

- Cisco IOS XE Fuji 16.9.1 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.

For more information, see Configuring Licenses on Cisco Catalyst 9000 Series Switches.

For a more detailed overview on Cisco Licensing, go to Cisco Software Licensing Guide.

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:

Permitted Combinations

DNA Essentials

DNA Advantage

Network Essentials

Yes

No

Network Advantage

Yes[1]

Yes

[1] 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 9300 Series Switches datasheet at:

http://www.cisco.com/c/en/us/products/collateral/switches/catalyst-9300-series-switches/datasheet-c78-738977.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.

- 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.

- 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:

- 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

- 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 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.

- The File System Check (fsck) utility is not supported in install mode.
