More SSIDs on single VLAN

[fabianoleso]

Hy to everibody.

I have a 1310 Wireless Bridge, configured as a "Root bridge with client" and on VLAN-1 I have 2 different SSIDs with two different security policies.This configuration seems to be working.I read that this mode is a misconfiguration.

Somebody can help me to understand what is wrong and why?

Thanks.

Hello,

in theory, only one SSID can be mapped to one VLAN (see the link below). Now since you appear to have it working with two SSID's, can you post your configuration, and indicate which IOS version you are running on your wireless bridge ?

Hi,

thank you for your response.

I post the configuration, but I don't remember the IOS Version on the Bridge.I suppose that the version is 12.3(8)JA.

Really, the 3 SSIDs are bound on the single VLAN in the Switch (VLAN-1).

Hello Fabiano,

looking at your configuration, it seems to me that it adheres to the standard. You have 4 VLAN's, and for each VLAN, you have one SSID:

dot11 ssid AAA

vlan 1

authentication open

guest-mode

dot11 ssid BBB

vlan 20

authentication open

dot11 ssid CCC

vlan 30

authentication open

dot11 ssid DDD

vlan 10

authentication open

authentication key-management wpa

wpa-psk ascii 7 XXXXXXXXXXXXXXXXX

I don't think the system lets you type in more than one, try e.g."

dot11 ssid AAA BBB CCC

and you will probably get a syntax error (I do not have a wireless router to test this myself, unfortunately...).

HTH,

In my configuration, I use "bridge-groupe 1" under the four subinterfaces Dot11Radio.

Do you think that this configuration is correct?

interface Dot11Radio0.1

encapsulation dot1Q 1 native

no ip route-cache

bridge-group 1

interface Dot11Radio0.10

encapsulation dot1Q 10

no ip route-cache

bridge-group 1

bridge-group 1 spanning-disabled

interface Dot11Radio0.20

encapsulation dot1Q 20

no ip route-cache

bridge-group 1

bridge-group 1 spanning-disabled

interface Dot11Radio0.30

encapsulation dot1Q 30

no ip route-cache

bridge-group 1

bridge-group 1 spanning-disabled

interface FastEthernet0

no ip address

no ip route-cache

interface FastEthernet0.1

encapsulation dot1Q 1 native

no ip route-cache

bridge-group 1
