7.4(100.60) 7.4(110.0) 7.6(120.0)

Description (partial)

Symptom:
With an AP1130 or AP1240 running 7.4 code in FlexConnect mode, serving multiple local-switching SSIDs with vlan mapping enabled, changing the VLAN mapping on one SSID to match the VLAN already assigned to another VLAN mapping on the same AP, will result in corrupted VLAN mappings to the SSIDs "below" the modified one (in the sense of the order they're installed in the radio).

This issue would cause clients to stop forwarding traffic on this AP (i.e. after roaming to an AP in this state) and/or forwarding traffic on the incorrect VLAN (if first associating to this AP).

Conditions:
- AP1130/1240 in FlexConnect with VLAN support
- Multiple SSIDs in Local-switching
