Environment : Controller -- Switch -- AP ))) Station

 

Association ID is unique in each BSSID of AP.


For checking the AID in controller CLI, using "show ap association "

(ArubaChang) #show ap association ?
ap-group                Filter on AP group
ap-name                 Filter on AP name
bssid                   Filter on AP MAC Address
channel                 Filter on channel
client-mac              Filter by client MAC Address
essid                   Filter on ESSID
ip-addr                 Filter on AP IP Address
ip6-addr                Filter on IPv6 Address
phy                     Filter on PHY type (a, b, or g)
remote                  Show association table for Bridge mode APs
voip-only               Show VoIP Client information only

One more station(70:f1:a1:54:f5:49) associated to BSSID (00:24:6c:5e:6b:20) and it's aid is "2".
