No SSID are Broadcasting

[jmarshman]

Hello,

I was wondering if someone out there could help me with a problem with our WLAN.  We recently received our WLC 5508, AP and switches to setup our WLAN but I'm having trouble getting it all to work.  It's been months since the course and I'm having trouble troubleshooting the problem.

I've setup the WLC, AP and switches and I have network connectivity to all.  The WLC see's my AP and I have all my WLAN and interfaces configured (SSID broadcast is enabled) but I still don't see any SSID coming from the AP.

Help!

Have you setup any AP groups? What version code?

edit...Scott beat me to it, but yes check to make sure your 802.11a and/or 802.11b/g networks are enabled under the Wireless section.

[jmarshman]

To make things easy I only have one AP up so far and the operational status is "up"

[Scott Fella]

Make sure you have the 802.11an and 802.11bgn radios enabled. If your using ap groups, make sure you have added the AP's and SSIDs to the correct ap group. You do see all you AP's up and radios show up or down?

Thanks,

Operational status of the ap is "up" and I'm not using AP groups.

[Scott Fella]

Your SSID enabled?

[blakekrone]

Can you post the output of show wlan , show ap config 802.11a summary, show ap config 802.11b summary?

[Scott Fella]

Is it an ap with external anetnna?  Do you have antenna's installed on that AP?  If so, I don't know if they are dual mode or not, but make sure the antennas are on the correct antenna ports.  Usually the blue bot is the 5ghz.

We have  AIR-CAP3502I-A-K9 devices with internal antenna.

Well looks like it should be working... maybe a bad AP.  I would try a different one and see.

[Stephen Rodriguez · Accepted solution]

Jason,

     the defaul AP group will only broadcast for WLAN 1-16.  Your WLAN are running as 104,105 and 199.  You need to create a new AP group, and add the WLAN(s) to it.  Then when you put the AP in the group it should start working.

Good catch, I was just looking at that myself when I saw the config. I've seen that before with people wanting to match the WLAN ID to your VLAN ID. Doesn't work out that well unless you create the ap groups!

[jmarshman]

I'm going to create a new AP group and try it again.  I'll keep you posted.

I'd also like to mention that the training I took was with the 4400 series running older code, thus making the traing manuals useless.
