Release Notes for Cisco Catalyst 9400 Series Switches, Cisco IOS XE Cupertino 17.8.x
Introduction
Cisco Catalyst 9400 Series Switches are Cisco’s leading modular enterprise switching access platform 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 Unified Access Data Plane (UADP) 2.0 and UADP 3.0. 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.
Cisco Catalyst 9400 Series Switches are enterprise optimized with a dual-serviceable fan tray design, side to side airflow, and are closet-friendly with a16-inch depth

ROMMON and CPLD Versions
ROM Monitor (ROMMON)
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.
Complex Programmable Logic Device (CPLD)
CPLD refers to hardware-programmable firmware. CPLD upgrades may be required to resolve firmware defects, or to support new features, but there may not be new versions with every release. CPLD version upgrade process must be completed after upgrading the software image.
The following table provides ROMMON and CPLD version information for the Cisco Catalyst 9400 Series Supervisor Modules. For ROMMON and CPLD 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 ROMMON
To know the ROMMON or bootloader version that applies to every major and maintenance release, see ROMMON and CPLD 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.
-
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
-
Golden ROMMON upgrade is only applicable to Cisco IOS XE Amsterdam 17.3.5 and later releases.
-
Golden ROMMON upgrade will fail if the FPGA version is 17101705 or older. To upgrade the FPGA version, see Upgrading the Complex Programmable Logic Device Version.
-
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.

Cisco IOS XE Cupertino 17.7.x or earlier releases. |
![]() Note |
New switch models that are introduced in a release cannot be downgraded. The release in which a module is introduced is the minimum software version for that model. We recommend upgrading all existing hardware to the same release as the latest hardware. |
The sample output in this section shows downgrade from Cisco IOS XE Cupertino 17.8.1 to Cisco IOS XE Cupertino 17.7.1, 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:

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:
|
Upgrading the Complex Programmable Logic Device Version
You can trigger a CPLD version upgrade after upgrading the software image. During CPLD upgrade, the supervisor module automatically power cycles. This completes the CPLD upgrade process for the supervisor module but also causes traffic disruption. Therefore, auto-upgrade of CPLD is not supported. You must manually perform CPLD upgrade.
Upgrading the CPLD Version: High Availability Setup
Beginning in the privileged EXEC mode, complete the following steps:
Before you begin
When performing the CPLD version upgrade as shown, the show platform command can be used to confirm the CPLD version after the upgrade. This command output shows the CPLD version on all modules. However, the CPLD upgrade only applies to the supervisors, not the line cards. The line cards CPLD version is a cosmetic display. After the upgrade is completed in a high availability setup, the supervisors will be upgraded, but the line cards will still show the old CPLD version. The version mismatch between the supervisors and line cards is expected until a chassis reload.
Procedure
Step 1 |
Upgrade the CPLD Version of the standby supervisor module Enter the following commands on the active supervisor:
The standby supervisor module reloads automatically and the upgrade occurs in ROMMON. During the upgrade, the supervisor module automatically power cycles and remains inactive for approximately 5 minutes. Wait until the standby supervisor module boots up and the SSO has formed (HOT) before you proceed to the next step; this takes approximately 17 minutes. |
||
Step 2 |
Perform a switch over
This causes the standby supervisor (on which you have completed the CPLD upgrade in Step 1) to become the active supervisor module |
||
Step 3 |
Upgrade the CPLD Version of the new standby supervisor module Repeat Step 1 and all its substeps.
|
Upgrading the CPLD Version: Cisco StackWise Virtual Setup
Beginning in the privileged EXEC mode, complete the following steps:
Procedure
Step 1 |
Upgrade the CPLD version of the standby supervisor module Enter the following commands on the active supervisor: |
Step 2 |

The upgrade occurs in ROMMON. During the upgrade, the supervisor module automatically power cycles and remains inactive for approximately 5 minutes. Wait until the standby supervisor module boots up and the SSO has formed (HOT) before you proceed to the next step; this takes approximately 17 minutes. |
Step 3 |
Perform a switch over
This causes the standby supervisor (on which you have completed the CPLD upgrade in step 1) to become the active supervisor module |
Step 4 |
Upgrade the CPLD version of the new standby supervisor module Perfom Steps 1 and 2, including all substeps, on the new standby supervisor module |
Upgrading the CPLD Version: Single Supervisor Module Setup
Beginning in the privileged EXEC mode, complete the following steps:

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 these datasheets for Cisco Catalyst 9400 Series Switches:
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.
-
-
Hardware limitations—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.
-
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)
-
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. This applies to both a single and dual supervisor module setup.
-
While performing ISSU from Cisco IOS XE Fuji 16.9.x to Cisco IOS XE Gibraltar 16.12.x, if interface-id snmp-if-index command is not configured with OSPFv3, packet loss can occur. Configure the interface-id snmp-if-index command either during the maintenance window or after isolating the device (by using maintenance mode feature) from the network before doing the 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.
-
-
M.2 SATA SSD drive: With bootloader version 16.6.2r, you cannot access the M.2 SATA SSD drive at the ROMMON prompt (
rommon> dir disk0
). The system displays an error message indicating that the corresponding file system protocol is not found on the device. The only way to access the drive when on bootloader version 16.6.2r, is through the Cisco IOS prompt, after boot up. -
No service password recovery—With ROMMON versions R16.6.1r and R16.6.2r, the 'no service password-recovery' feature is not available.
-
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 witched virtual interfaces (SVI) is supported.
-
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.
-
-
Redundancy—The supervisor module (hardware) supports redundancy. Software redundancy is supported starting with Cisco IOS XE Everest 16.6.2. However, the associated route processor redundancy (RPR) feature is not supported.
Before performing a switchover, use the show redundancy , show platform , and show platform software iomd redundancy commands to ensure that both the SSOs have formed and that the IOMD process is completed.
In the following sample output for the show redundancy , note that both the SSOs have formed.Switch# show redundancy Redundant System Information : ------------------------------ Available system uptime = 3 hours, 30 minutes Switchovers system experienced = 2 Standby failures = 0 Last switchover reason = active unit removed Hardware Mode = Duplex Configured Redundancy Mode = sso Operating Redundancy Mode = sso Maintenance Mode = Disabled Communications = Up Current Processor Information : ------------------------------- Active Location = slot 3 Current Software state = ACTIVE Uptime in current state = 2 hours, 57 minutes Image Version = Cisco IOS Software [Fuji], Catalyst L3 Switch Software (CAT9K_IOSXE), Version 16.8.1, RELEASE SOFTWARE (fc3) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2018 by Cisco Systems, Inc.

This indicates that the IOMD processes are completed.Switch# show platform Chassis type: C9407R Slot Type State Insert time (ago) --------- ------------------- --------------------- ----------------- 1 C9400-LC-24XS ok 3d09h 2 C9400-LC-48U ok 3d09h R0 C9400-SUP-1 ok, active 3d09h R1 C9400-SUP-1 ok, standby 3d09h P1 C9400-PWR-3200AC ok 3d08h P2 C9400-PWR-3200AC ok 3d08h P17 C9407-FAN ok 3d08h <output truncated>
-
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.
-
Uplink Symmetry—When a redundant supervisor module is inserted, we recommend that you have symmetric uplinks, to minimize packet loss during a switchover.
Uplinks are said to be in symmetry when the same interface on both supervisor modules have the same type of transceiver module. For example, a TenGigabitEthernet interface with no transceiver installed operates at a default 10G mode; if the matching interface of the other supervisor has a 10G transceiver, then they are in symmetry. Symmetry provides the best SWO packet loss and user experience.
Asymmetric uplinks have at least one or more pairs of interfaces in one supervisor not matching the transceiver speed of the other supervisor.
-
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.
-
The File System Check (fsck) utility is not supported in install mode.
