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.

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.

Open Shortest Path First Nonstop Routing (OSPF NSR) |
Enables a device with redundant Route Processors (RPs) to maintain its Open Shortest Path First (OSPF) state and adjacencies across planned and unplanned RP switchovers, by checkpointing state information from OSPF on the active RP to the standby RP. OSPF uses this checkpointed information to continue operation without interruption when the switchover to standby RP occurs.
See IP Routing.
(Network Advantage) |
OSPFv2 Loop-Free Alternate (LFA) IP Fast Reroute (IP FRR) |
Enables Open Shortest Path First version 2 (OSPFv2) to use a precomputed alternate next hop to reduce failure reaction time when the primary next hop fails. You can configure a per-prefix LFA path that redirects traffic to a next hop other than the primary neighbor.

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.

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.

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:
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.
