Aironet 1231 problem with broadcasting 2 SSIDs.

Hello,

I have several Aironet 1231 APs most running 12.3(8)JEA software. There are 4 SSIDs on (each in separate VLAN), with only one broadcasting (called pubwifi). The broadcasting one is an open, unencrypted network:

dot11 ssid pubwifi

   vlan 8

   authentication open

   guest-mode

After adding another braodcasting SSID (encrypted, separate VLAN), I encountered weird situation: my WiFi clients are unable to connect to pubwifi. It is not showing in the available networks or is showing as an "unknow" network. New encrypted/bradcasting ssid is advertaising just fine. Any ideas what's causing this?

Here's the new ssid config:

dot11 ssid newwifi

   vlan 14

   authentication open

   authentication key-management wpa

   mbssid guest-mode

   wpa-psk ascii 7 106E243A

Of course, I also ran mbssid command on interface Dot11Radio0.

Thank you,

forman

Aironet 1231 problem with broadcasting 2 SSIDs.

Hey Leo,

I'm not sure how to interpret your answer?

Here's what I currentlly have configured:

dot11 ssid pubwifi                      ### existing broadcasting, open network

   vlan 8

   authentication open

   guest-mode

interface FastEthernet0.8

encapsulation dot1Q 8

no ip route-cache

bridge-group 8

bridge-group 8 input-address-list 700

bridge-group 8 output-address-list 700

no bridge-group 8 source-learning

bridge-group 8 spanning-disabled

New encrypted, broadcasting SSID config:

dot11 ssid newwifi

   vlan 14

   authentication open

   authentication key-management wpa

   mbssid guest-mode

   wpa-psk ascii 7

interface FastEthernet0.14

encapsulation dot1Q 14

no ip route-cache

bridge-group 14

no bridge-group 14 source-learning

bridge-group 14 spanning-disabled

and config for:

interface Dot11Radio0

mbssid                                 ### already enabled

Any other ideas? Right now, newwifi (encrypted) is broadcasting fine and is visible to wifi clients... but the original pubwifi (open) is being presented to the wifi  clients as "unknown" network and clients won't automatically connect to  it. Some clients don't even see its broadcast, so I need to connect them manually as to non-broadcasting SSID.

thanks

This is what Leo means:

conf t

dot11 mbssid

!

dot11 ssid pubwifi

   vlan 8

   authentication open

   no guest-mode

   mbssid guest-mode

!

end

Aironet 1231 problem with broadcasting 2 SSIDs.

Thank you for clarifying this. As you can see, I have very limited knowledge of AP configs. Should I leave this as is?:

interface Dot11Radio0

mbssid                 ### I added that command when I was originally setting the newwifi SSID, it was part of the                             ### Cisco doc

Aironet 1231 problem with broadcasting 2 SSIDs.

yes, that needs to be under the radio.

Aironet 1231 problem with broadcasting 2 SSIDs.

Ok, after configuring:

dot11 mbssid

I didn't see mbssid in running config for interface Dot11Radio0 (which should be there), so I re-entered it, but to no avail:

sh run int dot11radio0

Building configuration...

Current configuration : 627 bytes

interface Dot11Radio0

I assume that this is normal, so I'm out to test this config. Thank you both for help with this.
