We are trying to configure an Aironet 1200 with multiple VLANs without much luck. At this point, I am stuck trying to get the VLANs working on our Catalyst 4006 Sup3 switch.
The FAS0 on the AP is connected to Gi4/23 on the 4006. When I configure port 4/23 for "trunk", traffic does not pass. When I configure the same port for "access VLAN 55", it works just fine. This is not what I'm reading in the "Using VLANs with Cisco Aironet Wireless Equipment. It says to use the "trunk" mode. But, I am not getting it to work.
Here is some other info:
IOS (tm) Catalyst 4000 L3 Switch Software (cat4000-IS-M), Version 12.1(8a)EW1
Config of the port on the 4006 that connects the AP (this does not work):
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,55,200,1002-1005
switchport mode trunk
description Cisco 1231 AP
If I change to these two lines to "access" instead of "trunk", traffic will pass and my wireless devices begin working.
What I have read and tried is using trunking with a native vlan (I tried using a L2 switch and a router behind it).
I had to specify the native vlan explicitly (switchport trunk native vlan NNN) on the switch.
In the Aironet the native VLAN had to be configured also explicitly (somewhere in ethernet link settings).
It then worked just fine, I could associate with different SSIDs, each of them corresponding to a different VLAN (different ranges of DHCP addresses, so that checking the ip address gives an indication on the VLAN).
Possibly this is way off the mark, I post this just in case...
I am having a similar problem. I am able to configure VLANS and the VLANS work as long as I am not using WEP keys. The device will authenticate but will not reieve DHCP. Apparently this is a known bug ,CSCec54099. If I assign an address it works fine.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
