Cisco AIR-LAP1142N-E-K9 bridge and AP mode configuration

Hi all,

I've got 2x 1142N access points. Both are running autonomous software.

they're both connected to Cisco 3750G's  (SW1 and SW2) in the following way:

SW1 - AP1 >>>> AP2-SW2

I'm trying to accomplish 2 things here:

- The AP's need to bridge the two wired LAN's  on the 5Ghz radio (dot11radio1)

- The AP's should try to advertise the same WLAN for Clients on the 2.4ghz radio (dot11radio0).

 

What works?

- The AP's bridge on the 5Ghz radio, this works fine. Clients can connect to devices across the bridge.

- Wireless clients can connect to fine to the wlan-client ssid on AP1. At AP2 the Dot11radio0 refuses to come up with different errors:

*Mar  1 07:10:50.825: %DOT11-4-NO_VALID_INFRA_SSID: No infrastructure SSID configured. Dot11Radio0 not started.
03:39:22: DOT11 EVENT:disc_start:Could not configure the radio.
*Mar  1 07:10:50.825: %LINK-5-CHANGED: Interface Dot11Radio0, changed state to reset
03:40:22: DOT11 EVENT:disc_config: root set device to 4D
*Mar  1 07:12:01.902: %DOT11-4-CANT_ASSOC: Interface Dot11Radio0, cannot associate: No Response
*Mar  1 07:12:06.912: %DOT11-4-CANT_ASSOC: Interface Dot11Radio0, cannot associate: Rcvd response from 64d9.896d.cc80 channel 13 2928

I'm using the configuration as per below; anybody got a clue what I'm doing wrong here?

on AP 2 under the Radio 0 it

on AP 2 under the Radio 0 it should be "station-role root", not non-root. Sorry I missed that in the config earlier.

On AP 2 you need to remove

On AP 2 you need to remove the Infrastructure-ssid command under the wlan-client SSID.  That command is for telling the AP that it uses that SSID to connect to another radio.

Hi Steve, I did that. Then i

Hi Steve,

 

I did that. Then i get the following error:

%DOT11-4-NO_VALID_INFRA_SSID: No infrastructure SSID configured. Dot11Radio0 not started.

 

My SSID configuration is as follows now:

 

AP2:

!
dot11 ssid wlan-bb
   authentication open
   infrastructure-ssid
!
dot11 ssid wlan-hs
   authentication open
   authentication key-management wpa version 2
   guest-mode
   wpa-psk ascii 0 test
!

 

Do you know how to explain that error?

AP1:

!
dot11 ssid wlan-bb
   authentication open
   infrastructure-ssid
!
dot11 ssid wlan-hs
   authentication open
   authentication key-management wpa version 2
   guest-mode
   wpa-psk ascii 0 test
