AP Up, but radios down?

Alright, on to the next issue. Now that I'm able to get these APs provisioned, 2 out of the 8 so far are coming to an "up" state but the radios are not coming up. I'm provisioning them in alternating AP groups, but I've seen it happen with both, so I know it's not related to the AP Group.

 

Any ideas what would be preventing the radios from coming on?

Re: AP Up, but radios down?

Could you start by giving us the output from a "show ap database" command? You can always do a "| include 135" if this only releates to the AP-135 that you are troubleshooting.

 

Thanks!

Thanks,

Re: AP Up, but radios down?

Have you configured anything non default in the ARM or radio profiles for the groups? Mode aware ARM can cause this if the interference levels are high.

Re: AP Up, but radios down?

Oh, and a "show ap active" output will help show what it's doing too.

 

What's the configuration like within the AP group? How many VAPs did you add?

Re: AP Up, but radios down?

Interestingly enough, after rebooting sometimes the radios come right up. However, I'm just basing whether the radios are up or not based on whether I see a channel assigned to the radio. Sometimes I do see channels assigned to the radios but the radio LEDs are not lit up on the APs. Should I be concerned about this?

 

I haven't done anything weird in the ARM profile at all. The only thing I changed it to was multi-band (I think it defaults single-band?)

On the commandline, type "show audit-trail" to see what you typed.  You might be able to figure it out.

Re: AP Up, but radios down?

I think we need to see your config (AP groups, VAPs and radio/ARM settings). Just a snapshot of those bits. And an output from a "show audit-trail", "show ap active" and "show ap database long".

 

The radio lights should definately be on if the AP is functioning as a normal AP (with a VAP), and has a tunnel to the controller up.

Re: AP Up, but radios down?

Alright, here's a good example. AP shows as up but no channels assigned and no radio LEDs.

 

As far as the config goes - I have two AP groups (group_a and group_b) but they use the same VAP, ARM profile, SSID profile... the only difference is the AP system profile... each different one has swapped LMS IPs to provide load balancing.

 

And just to reiterate... this is one subnet... the two controllers and the AP are connected by a simple, dumb switch.

 

show ap active:

 

(TerminalRoad-Master) #show ap active

Here's something interesting... I've got a mix of AP134s and AP135s. I've noticed a difference between them. When the 134s boot up, after they upgrade their image they show up as unprovisioned access points. However, the 135s come up and automatically show as "up" with radio channels assigned, in the AP group 'default', but are flagged inactive, and while the radio LEDs are on, they are amber, not green. 

 

When I provision these I'm setting a static IP (which is still valid on the subnet) but assigning a default gateway that doesn't currently exist on the network. I would think this should matter since the controller is only 1 hop away anyway.... right?

AP 134s need to be provisioned with the DB of the connected external antenna, otherwise they won't come up.

I'm definitely entering that. Actually I don't think it'll even let you provision with those fields blank. Well, at least it didn't let you back in the 3.x.x.x times.
