Hello, I have configured my AP with 3 VLANs (VLAN1=Native, VLAN4=Prod, VLAN5=Guest). The bvi1 int has an ip address of 172.16.0.81. however when I tried to connect to the AP via webbrowser or try to ping the ap (172.16.0.81) from it will loose connectivity after 2 minutes. When I do a "clear arp" on the AP, then I establish connection for another 2 minutes and loose it again.
Check if the IP address to interface BVI1 is in the same subnet as all the rest of your infrastructure. Not only should there be no other IP addresses on interfaces on the unit, there should be no other BVI interfaces.
