Prime & WLC interfaces down

[Bruno Dinis]

Hello all. After installing a backup controller a few months, I now have regurlarly those kind of critical alarms in Cisco Prime 3.0.2

I only got 2 conneted interfaces in my WLC0  (port 1 and port 2).. I recieve these traps saying that the remain ports are down.

This is an issue?
Cheers,

Bruno,

1) Jump on to the CLI and check which physical interfaces are connected with show port summary.

2) Shutdown any unused interfaces with config port adminmode # disable where # is the port number. In the example below I shutdown ports 5-8 as they are not in use. I've highlighted the bit where it changes the physical link from enable to disable.

Tried to disable port 8 and got the following error...

(Cisco Controller) >config port adminmode 8 disable
Blocked: Lag is enabled. Disabling the lag port is blocked when system is in redundancy state (SSO)

Thanks

Hmm I suspect you may have to disable LAG, restart your WLC, shutdown the unused ports after it has reloaded and then re-enable LAG and restart your WLC a final time.

worked like a charm.

Thanks buddy

Hi there,

we have the same Issue in an much newer Version of Prime (3.7.1). Is the procedure he same or can we use some kind of suppression via rule to solve this alarm Problem.

We did some kind of messing arround with the alarm policy but didn't find any working ones.

Thanks in advance.

Kind regards

Jan
