bootstrapping vs rebooting

Hello,

 

What is the most assured way to tell the difference between an AP that is bootstrapping vs an AP that is rebooting?

 

TIA,

"Show ap debug counters" will tell you.  

 

"show log system all" will also tell you who is bootstrapping or rebooting.

Re: bootstrapping vs rebooting

What is the difference between these two from a conceptual point of view? 

 

Is it:

 

Rebooting: happens for external reason

 

Bootstrapping: happens when told to manually?

 

I'm just confused because rebooting is technically short for "reboostrapping" considering that's where "boot" came from.

An access point, when it has contacted a controller will send heartbeats, typically one per second.  Each access point has a bootstrap threshold where if it misses 8 heartbeats it will rebootstrap.

 

During a Rebootstrap:

 

- The AP turns of its radios except those with bridge mode SSIDs
- It tries to establish communication with the current LMS using PAPI
- If unable to contact the current LMS (lms-ip) and there is a backup LMS, it will try to establish communication with the bkup-lms-ip as configured in the AP system-profile
If the AP is unable to contact an LMS, it will then initiate a full reboot

Re: bootstrapping vs rebooting

So what is the fix here? I have been seeing this with one of the APs

Please provide more information about your situation, or start a new thread.  It is not possible to tell if you even have a problem that needs to be fixed.

Re: bootstrapping vs rebooting

Here is the log. We monitor all APs thru Airwave and its been alerting for this one AP. As you see, AP itself is reachable. Let me know if you need more details.

Re: bootstrapping vs rebooting

You should type "show ap debug counters" to see how widespread the problem is. If the problem is with all aps, I would check to make sure that the uplink to the controller is big enough. The unwritten rule is that you need 1 gigabit connect room for every 100 APs that connects to to a controller. If it is happening to only one access point, I would check to make sure that the AP negotiated the proper speed and duplex on its switch port and that there is no congestion upstream of that AP.

Re: bootstrapping vs rebooting

What am I looking for in the debug counters to identify if there is an
issue? Controller has multiples gig uplinks and there are less than 100 APs
on this controller, so congestion is not an issue.

thanks
