 2025/03/12-11:40:20 WARN: Unexpected firmware version "10.5.6.3" on switch A, expected version is one of ["10.5.1.1P1"], the rest of switch output parsing code may return incorrect results

The switch monitoring script has not been updated with the newest firmware versions, so it does not recognize the firmware.

1. Log in to the affected Avamar Utility Node or the single node as admin.

2. Download the GoAV tool. See the following article for more information: Avamar: GoAV Product Tool for Management and Troubleshooting

3. Elevate to root privileges:

su -

4. Run the GoAV tool with the following options:

./goav fix-switch-firmware-config
