Configuring Universal Workgroup Bridge with Aironet 1130 series AP

laboutpost2 · ‎07-20-2015

I am relatively new to configuring IOS devices. I have an Aironet 1130 AG access point that I am trying to configure to associate with a Linksys WRT54g wireless router running DD-WRT. I am using universal workgroup bridge mode, and have specified the mac address as the mac address of the server connected to the 1130 via ethernet.

However, after trying many configurations, I still cannot communicate from the server to the wireless router. This is the current config:

hostname AP01
!
logging rate-limit console 9
!
no aaa new-model
ip domain name myDomain
!
!
no dot11 syslog
!
dot11 ssid mySSID
   authentication open
   authentication key-management wpa
   guest-mode
   wpa-psk ascii 7 0000160B105A581518274D
!
power inline negotiation prestandard source
!
!
!
bridge irb
!
!
interface Dot11Radio0
 no ip address
 no ip route-cache
 !
 encryption mode ciphers aes-ccm tkip
 !
 ssid mySSID
 !
 station-role workgroup-bridge universal 0033.8290.3257 ! Server MAC
 bridge-group 1
 bridge-group 1 spanning-disabled
!

!
interface BVI1
 ip address 10.0.0.50 255.0.0.0
 no ip route-cache
!
ip http server
no ip http secure-server
ip http help-path http://www.cisco.com/warp/public/779/smbiz/prodconfig/help/eag
bridge 1 route ip
bridge 1 aging-time 120
!
!
!
line vty 0 4
 login local
!
end

The 1130 seems to authenticate with the Linksys, because the router gives this detailed information:

00:33:82:90:32:57
dot11RSNAStatsSTAAddress=00:33:82:90:32:57
dot11RSNAStatsVersion=1
dot11RSNAStatsSelectedPairwiseCipher=00-0f-ac-4
dot11RSNAStatsTKIPLocalMICFailures=0
dot11RSNAStatsTKIPRemoveMICFailures=0
hostapdWPAPTKState=7
hostapdWPAPTKGroupState=0

Sometimes, however, the Linksys shows the MAC address of the FastEthernet interface on the 1130 instead of the server MAC.

I have the server, 1130, and Linksys router set up with static IPs. All have subnet mask 255.0.0.0.

Server: 10.0.0.20
1130 AP: 10.0.0.50
Linksys WRT54g: 10.0.0.1

Since I am new to the IOS world, I cannot tell what the issue is. Could it be an addressing issue? Or is it a routing issue?

Thanks,

Dia

Can you ensure your wired clients mac address is not aged out on the AP.

Refer this link

Few things to keep in mind:
- This wired client must exist. If the WGB does not detect that MAC address on its Ethernet interface, it associates to the WLAN using its own MAC address, which means that you see in the wireless space the WGB BVI1 MAC address instead of the client behind.
- When the non-802.11 client appears on the wired interface, the WGB disassociates then re-associates using this time the wired client MAC address.
- Are you really limited to one device in universal mode? Well not really, you are limited to one MAC address in the wireless space. If that address is the MAC address of a router connected to the WGB, and if you have 10 devices behind that router, fine! Only 1 MAC address is seen and all is well.
