[c-nsp] Aironet 1230 and multiple VLANs

Hello

When running multiple VLANs to an Aironet AP, where do I set the IP address?

I've used Fa0.8 (management VLAN) but I have periodic errors in the log:

  Jun  8 08:29:57.966: %IP_SNMP-3-SOCKET: can't open UDP socket
  Jun  8 08:29:57.966: Unable to open socket on port 161

Is the FastEthernet sub-interface the right one to set an address on? 
Should I be setting an address on the BVI interface instead?

Configuration is as follows:

  interface FastEthernet0
   no ip address
   no ip route-cache
   speed 100
   full-duplex
  !
  interface FastEthernet0.8
   encapsulation dot1Q 8 native
   ip address 10.180.0.65 255.255.255.0
   no ip route-cache
   bridge-group 8
   no bridge-group 8 source-learning
   bridge-group 8 spanning-disabled
  !
  interface FastEthernet0.10
   encapsulation dot1Q 10
   no ip route-cache
   bridge-group 10
   no bridge-group 10 source-learning
   bridge-group 10 spanning-disabled
  !
  interface Dot11Radio0
   no ip address
   no ip route-cache
   !
   encryption vlan 8 mode ciphers tkip 
   !
   encryption vlan 10 key 1 size 128bit 7 $WEP_KEY transmit-key
   encryption vlan 10 mode wep mandatory 
   !
   ...
  !
  interface Dot11Radio0.8
   encapsulation dot1Q 8 native
   no ip route-cache
   bridge-group 8
   bridge-group 8 subscriber-loop-control
   bridge-group 8 block-unknown-source
   no bridge-group 8 source-learning
   no bridge-group 8 unicast-flooding
   bridge-group 8 spanning-disabled
  !
  interface Dot11Radio0.10
   encapsulation dot1Q 10
   no ip route-cache
   bridge-group 10
   bridge-group 10 subscriber-loop-control
   bridge-group 10 block-unknown-source
   no bridge-group 10 source-learning
   no bridge-group 10 unicast-flooding
   bridge-group 10 spanning-disabled
  !
