Failover of 2504 WLCs

[Sandeep Choudhary]

Hello All,

I have concern regarding the faiolver of 2 WLCs.

1. One Active_WLC(2504) have a full licence of 15 Access points.

2. 2nd Seconday_WLCs(2504) have a normal licenece (Without any AP licenece-Zero AP Count License).

Now my questions are:

1. If first WLCs goes down due to any kind of problem then can secondary WLCs comes up and takover of all APs.

2. if Yes, then How may days or hours...These APs will connect to the WLC.

3.If first WLCs comes up after some days, then can this WLC automaticall tak over the situation??

Regards

The 2504 requires license for access points. The 2504 doesn't support HA which is what you are describing. The 5508's and the WiSM2 are some that do support HA which came out on v7.3.

Your better off just having ap license on both the 2504 and put half the APs on one and the other half on the other 2504.
