Is it possible to create multiple BVI interfaces and assign each of them IP addresses of different VLANs?
I have this AP and it's broadcasting 2 SSIDs (1 on VLAN1 and another on VLAN17). They work fine. The BVI 1 has IP 10.0.1.100/24 and BVI 17 has 172.17.252.100/16. The switch is 3750 and vlan1 interface has IP 10.0.1.10/24 and vlan17 interface has IP 172.17.254.10/16. However only BVI is pingable but not BVI 17. Can I use BVI 17 interface and its IP for management? Thanks!

If you have vlan 1 and 17 working, then I assume you have subinterfaces for both the radio and the fast ethernet port? And each sub-interface is correctly mapped to a bridge-group of the BVI?
Maybe need to add "bridge 17 route ip"?
Post your config please?

Here is the config. I can't put "bridge 17 route ip" on. It says that route ip is only allowed on bridge group 1. Thanks!
