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.

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 9600 Series Switches 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.

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 9600 Series Supervisor Modules. 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
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 Cisco StackWise Virtual setup, upgrade the active and standby supervisor modules.
-
In case of a High Availability set up, upgrade the active and standby supervisor modules.
-
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.

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 9600 Series Switches fall under these base or add-on license levels.
Base Licenses
-
Network Advantage
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 Advantage
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 Gibraltar 16.11.1 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.
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-Advantage) are ordered and fulfilled only with a perpetual or permanent license type.
-
Add-on licenses (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.
-
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 9600 Series Switches datasheets at:
Limitations and Restrictions
-
Auto negotiation: The SFP+ interface (TenGigabitEthernet0/1) on the Ethernet management port with a 1G transceiver does not support auto negotiation.
-
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. -
Convergence: During SSO, a higher convergence time is observed while removing the active supervisor module installed in slot 3 of a C9606R chassis.
-
Hardware Limitatons — Optics:
-
Installation restriction for C9600-LC-24C linecard with CVR-QSFP-SFP10G adapater —This adapter must not be installed on an even numbered port where the corresponding odd numbered port is configured as 40GE port. For example, if port 1 is configured as 40GE, CVR-QSFP-SFP10G must not be installed in port 2.
Installation restriction for C9600-LC-24C linecard with CVR-QSFP-SFP10G adapater — If you insert a 40-Gigabit Ethernet Transceiver Module to odd numbered port, the corresponding even numbered port does not work with CVR-QSFP-SFP10G adapter.
-
-
Hardware Limitatons — Power Supply Modules:
-
Input voltage for AC power supply modules—All AC-input power supply modules in the chassis must have the same AC-input voltage level.
-
Using power supply modules of different types—When mixing AC-input and DC-input power supplies, the AC-input voltage level must be 220 VAC.
-
-
In-Service Software Upgrade (ISSU)
-
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.
-
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.
