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.

Redundant System Information :

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 active

9400-1#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:

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

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
