ssid broadcast

hi All,

I am having some trouble getting the ssid to broad cast.  Below is my config.  Is this the correct way to do it?

dot11 ssid conferenceroom
   information-element ssidl advertisement

interface Dot11Radio0
no ip address
no ip route-cache
!
ssid conferenceroom
!
antenna gain 0
station-role root
bridge-group 1
bridge-group 1 subscriber-loop-control
bridge-group 1 block-unknown-source
no bridge-group 1 source-learning
no bridge-group 1 unicast-flooding
bridge-group 1 spanning-disabled
!

thanks in advance!

Do I have to enable a vlan?  I only want to have one ssid.

Re: ssid broadcast

Hi,

the command leolahoo gave was for the case when you have several vlans.

Just forget his 2 commands (remove them) and put "guest-mode" in the dot11 ssid config (instead of mbssid guest-mode).

That will work like a charm ;-)

Re: ssid broadcast

Here is the config.  But it still isn't working.  What is strange is that I can see an ssid with the mac address of my dot11radio 0 interface with the password I had once set for wpa2.  I have unplugged and replugged the power supply to do a reset, but still same  thing.

It is strongly suggested that you create a new username with privilege level

Replace and with the username and password you want to

Re: ssid broadcast

dot11 ssid conferenceroom
   guest-mode

Add" authentication open" to the dot11 ssid configuration.

It should be ok then.

Re: ssid broadcast

hi, Thanks for your answer.  I am still not quite there yet.  I am using 4 laptops for testing, 2 dell laptops and 2 hp.  Everything works fine on the dell laptops, but not on the hp.  I have an air1232ag, the ssid setup on the 1232ag is seen by all the laptops.

the config on the air 1232 is

dot11 ssid surferrosa
   authentication open
   guest-mode

interface Dot11Radio0
no ip address
no ip route-cache

ssid surferrosa

Re: ssid broadcast

The config is really the most simple you can get ...

Are you having old drivers on the HP ?

My last wild guess is that if you have a european AP, it could be on channel 13 while the clients don't support that channel because their chip is US-based.

Try setting the channel manually under the radio interface ("channel x" command).

Re: ssid broadcast

bingo!  I set it to channel 1 and I can see the ssid. Thanks for you help!   You are the man!

What is the best channel so that I won't have any issues with laptops from different countries?

Cisco Employee

Re: ssid broadcast

1, 6 and 11 are the super standards channels. Pick any of the 3 depending on your surroundings (you might have neighbors on 6 and 11 or on all 3, we can't know).

I'm glad I could help. I've already pulled some hair having the same problem before realizing the AP was sitting on channel 13.

Re: ssid broadcast

Hi,

MBSSID is only if you want to have multiple SSIDs broadcasting on the same AP.

this Implies having multiple VLANs configured and that is why you got that message when adding  the command on the radio.

If you have a single SSID that you want to broadcast you can simply do:

ap.yourdomain.com.(config)#dot11 ssid conferenceroom
ap.yourdomain.com.(config-ssid)#guest-mode

HTH,

Tiago
