We recently installed 2 4402 WLCs. I configured Mobility group and split the APs between 2 WLCs by configuring Primary Controller on each AP. No secondary or tertiary Controller was configured.
Now when WLC1 goes down, the APs on WLC1 register with the WLC2. However, when WLC1 comesback up the APs don't fall back to WLC1. They stay associated with WLC2 until they are rebooted.
is this normal or am i missing anything?
