Another 5760 WLC and 5760 HA WLC question

[barryfowles]

Hi all,

I have two 5760 Controllers, one licensed and one a HA SKU Controller. I have configured them for N+1 fail-over. They are configured to be in the same L2 management network and in the same Mobility Group. The customer had an issue and tried to fail-over the APs to the secondary controller at the weekend but only about 15 out of 185 APs actually failed-over. Does anyone have any thoughts as to why they all didn't fail-over. The controllers are both running 3.3.3SE code and High Availability under Global AP Configuration is set on bot the primary and secondary.

Thanks

I think that I may be hitting the following bug:

CSCuo63153 – AP HA Switchover Primary/Secondary fails on 3.3.3 (will be fixed in 3.3.4)

Apparently the problem is experienced when setting Primary/Secondary HA  via the GUI.

Hi Barryfowles,

Could you share some notes that you used to install 5670WLC in HA mode ?

Thanks in advance
