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

SDiekmeijer — Mon, 05 Jul 2021 08:41:33 GMT

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 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.

HTH,

Steve

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

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.

HTH,

Steve

That was it indeed Steve!

That was it indeed Steve! Many thanks, it works like a charm now 🙂
