Hi Experts,

I initially set up my cisco wireless ap on a network where I have several vlans, the config works great.  I have been asked to ship one of my ap to another site where they do not have vlans and I wanted to make sure my config would work once shipped.  I am including the important part of this config change.  I understand the ip address and pretty normal stuff will change and I have that under control its this part of the config I want to make sure is ok.  

This is my initial config:

dot11 ssid <ssid>
   vlan 90
   authentication open eap eap_methods
   authentication key-management wpa
!

interface Dot11Radio0
 no ip address
 no ip route-cache
 !
 encryption vlan 90 mode ciphers tkip
 !
 encryption vlan 75 mode ciphers aes-ccm tkip
 !
 ssid <ssid>
 !
 speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0 12.0 18.0 24.0 36.0 48.0 54.0
 station-role root
 bridge-group 1
 bridge-group 1 block-unknown-source
 no bridge-group 1 source-learning
 no bridge-group 1 unicast-flooding
 bridge-group 1 spanning-disabled
!
interface Dot11Radio0.75
 encapsulation dot1Q 75
 no ip route-cache
!
interface Dot11Radio0.90
 encapsulation dot1Q 90
 no ip route-cache
 bridge-group 90
 bridge-group 90 subscriber-loop-control
 bridge-group 90 block-unknown-source
 no bridge-group 90 source-learning
 no bridge-group 90 unicast-flooding
 bridge-group 90 spanning-disabled
!
interface FastEthernet0
 no ip address
 no ip route-cache
 duplex auto
 speed auto
!
interface FastEthernet0.1
 encapsulation dot1Q 1
 no ip route-cache
!
interface FastEthernet0.40
 encapsulation dot1Q 40 native
 no ip route-cache
 bridge-group 1
 no bridge-group 1 source-learning
 bridge-group 1 spanning-disabled
!
interface FastEthernet0.90
 encapsulation dot1Q 90
 no ip route-cache
 bridge-group 90
 no bridge-group 90 source-learning
 bridge-group 90 spanning-disabled


This is my reconfigured AP with no vlans:

dot11 ssid <ssid>
   vlan 1
   authentication open eap eap_methods
   authentication key-management wpa
!

interface Dot11Radio0
 no ip address
 no ip route-cache
 !
 encryption vlan 1 mode ciphers tkip
 !
 ssid <ssid>
 !
 speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0 12.0 18.0 24.0 36.0 48.0 54.0
 station-role root
 bridge-group 1
 bridge-group 1 block-unknown-source
 no bridge-group 1 source-learning
  no bridge-group 1 unicast-flooding
 bridge-group 1 spanning-disabled
!
interface Dot11Radio0.1
 no ip route-cache
!
interface FastEthernet0
 no ip address
 no ip route-cache
 duplex auto
 speed auto
!
interface FastEthernet0.1
 encapsulation dot1Q 1 native
 no ip route-cache
 bridge-group 1
 no bridge-group 1 source-learning
 bridge-group 1 spanning-disabled

Also, since I am not using vlans, can this be put on a normal switchport and not a trunk port?

Thanks,

R

Get rid of the subintefaces (.1).. That will still assume you have vlan 1 configured on a switch, and that the AP is connected to a dot1q trunk port.

change it to look like:
==snip===
!
interface Dot11Radio0
 no ip address
 no ip route-cache
 !
 no shut
 !
 ssid xxxxxxx
 !
 station-role root
 bridge-group 1
 bridge-group 1 subscriber-loop-control
 bridge-group 1 block-unknown-source
 no bridge-group 1 source-learning
 no bridge-group 1 unicast-flooding
 bridge-group 1 spanning-disabled
!
!
interface FastEthernet0
 no ip address
 no ip route-cache
 no shut
 bridge-group 1
 no bridge-group 1 source-learning
 bridge-group 1 spanning-disabled
 hold-queue 160 in
!
!
interface BVI1
 ip address x.x.x.x  x.x.x.x
 no ip route-cache
 no shut
!
==snip===

then you will be able to hang it from a regular switch port (non trunked).

Ah, gotcha.  So the config I sent along would work if I have an ip address on vlan 1 of my switch correct?  I believe I do.  I apologize when I said no vlans, that was obviously the wrong wording.

sure.  if the switch port was a dot1q trunk, and the switch had vlan 1 defined (by default it is there).  it would have been good.  
if you were putting it in a switch that didn't do trunking, or have vlans (for example an unmanged switch), then you would need to remove the sub interfaces.
