I have to locations with wlc in an redundant configuration. For one wlan I use the H-REAP feature. I defined the management-interface for that wlan. The wlan configuration on both wlc is identical. One difference is in the management-interface configuration. On the first wlc the management-interface is tagged with vlan 55 and on the second wlc the interface is untagged.
With this configuration the vlan-mapping change if the ap join the other wlc. When the ap leave the first wlc to the second wlc in the vlan-mapping appear vlan 1 instead of vlan 5. In the other way the vlan-mapping change to vlan 55 instead of vlan 5. It seems that the tagging of the management-interface is the problem. Is that true or exists other problems?
