Available Languages
Introduction
This document describes a step-by-step procedure on how to upgrade the Complex Programmable Logic Device (CPLD) version on a Catalyst 9400 StackWise Virtual Link (SVL) setup.
Prerequisites
Requirements
Cisco recommends that you have basic knowledge of Stackwise-Virtual setup and configuration on catalyst 9400.
Components Used
The information in this document is based on the PID: C9404R software and hardware versions.
Modules:
C9400-SUP-1XL
C9400-LC-24XS
SW Version: 17.09.4a
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.
Topology
Problem
In Catalyst 9400, while upgrading the Cisco IOS® version in some rare cases the CPLD version of the device is not upgraded. The CPLD and the Rommon version for the particular version can be checked from https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9400/software/release/17-13/release_notes/ol-17-13-9400/rommon_versions.html link.

In this case, the CPLD of the standby did not get upgraded after the upgrade.
Upgrade Procedure
Step 1. Use the show redundacny in order to verify if the SVL is working fine.
9400-1#show redundancy
Redundant System Information :
------------------------------
Available system uptime = 4 minutes
Switchovers system experienced = 0
Standby failures = 0
Last switchover reason = none
Hardware Mode = Duplex
Configured Redundancy Mode = sso
Operating Redundancy Mode = sso
Maintenance Mode = Disabled
Communications = Up
Current Processor Information :
-------------------------------
Active Location = Switch 1
Current Software state = ACTIVE
Uptime in current state = 4 minutes
Image Version = Cisco IOS Software [Cupertino], Catalyst L3 Switch Software (CAT9K_IOSXE), Version 17.9.4a, RELEASE SOFTWARE (fc3)

BOOT = bootflash:packages.conf;
Peer Processor Information :
----------------------------
Standby Location = Switch 2 >>>>>>>>>>Switch 2 is standby
Current Software state = STANDBY HOT
Uptime in current state = 0 minutes

BOOT = bootflash:packages.conf;
Step 2. In order to upgrade the CPLD version use this command:
upgrade hw-programmable cpld filename bootflash: switch {1-2} RP active9400-1#upgrade hw-programmable cpld filename bootflash: switch 2 R0
Firmware upgrade requires the SVL member to reload. Do you want to proceed?(y/n)y
Use cli 'redundancy reload peer' to upgrade the firmware on peer
9400-1#redundancy reload peer
Stack is in Half ring setup; Reloading a switch might cause stack split
Reload peer [confirm]
Preparing to reload peer
Step 3. Here you can see that the CPLD is getting upgraded:
Chassis 2 reloading, reason - Admin reload CLI

Step 4. Confirm if the CPLD is upgraded on standby:

1 20062105 17.10.1r >>>>>>>>>>CPLD got upgraded
2 20062105 17.10.1r >>>>>>>>>>CPLD got upgraded
Step 5. In the case, if the CPLD version of the Active Switch needs to be upgraded, you must pursue these steps:
1. Do a switchover
9400-1#redundency force-switchover >>>>>>>>>>Initially Switch 1 is active and Switch 2 is standby.
After switchover it is vise-versa
2. Upgrade the CPLD version of previous active [now standby] with the command:
9400-1#upgrade hw-programmable cpld filename bootflash: switch 1 R0
3. Reload the the standby
9400-1#redundancy reload peer
