CISCO 3504 Break HA Configuration

crange — Tue, 28 Nov 2023 18:44:31 GMT

Hi everyone, I just have a question, Once we break the HA, the configuration remain the same in Both controllers? I think the only thing that I have to do is configure a new management ip for standby controller and the configuration will remain the same? of course I also have to update configuration for some interfaces but I gonna be able to have 2 controllers working on stand alone mode right?

Disabling SSO on HA Pair

1. On primary controller, disable SSO using the command:

Config redundancy mode disable

The Active and Standby WLCs reboot once this command is executed.

The standby controller, when it comes back after the reboot, has the same IP address on interfaces as the primary controller and all the ports disabled.

2.On the standby controller, re-enter the correct IP addresses corresponding to the management and dynamic interfaces and execute the following command:

Config port adminmode all enable

You will get two standalone wlc

Bur remember you need to make dynamic interfaces IP different otherwise you will see traffic disrupt due to ip conflicts.

According to doc. YES

Change mgmt and dynamic interface IP.
