Random Drops For Whole Site

Hi,

 

We have been experiencing random drops in connectivity for a whole site a couple of times a day.  I noticed in the logs that it is showing the tunnel is going down and up but not sure how further to troubleshoot what might be the cause - can any one help? Logs below:


Virtual Mobility Master running Aruba OS 8.2.2.5

Re: Random Drops For Whole Site

On the master, type "show master-local stats" to see if any heartbeats are indeed being dropped between the master and the MDs.

On the active controller on that site?&nbsp;

Re: Random Drops For Whole Site

Last drop was around noon today.  I would do a "clear master-local stats" to reset the counters and see how they grow in the next 24 hours.

 

MDs (controllers) do not need persistent connectivity with the MM.

Re: Random Drops For Whole Site

Clear master local stats on the controller itself or on the mobility master?
&nbsp;
Also do you think maybe this is just showing the connection goes down between the controller and the MM - but that something else is causing the drop to the whole site as well as causing the issue with the communication to MM?
&nbsp;
Is there anything else i should be checking for in the logs ? I noticed this:

Re: Random Drops For Whole Site

Just the controller, for now.

 

I would type "show log system 50" and see if there are any AP bootstraps.  If those APs are at the same site, and they have bootstraps, you have a local issue.

Re: Random Drops For Whole Site

OK i have cleared the master-local stats

 

I did a show log system 50 but no AP boot straps

 

It is all the Aps and controllers on one site however that have the issue - happened again at 16:35 last night

Re: Random Drops For Whole Site

Is this a Virtual Machine?  I also saw a log before that said you are running this controller at 90% capacity, which is not advised (EDIT: 80% is the typical advice in a large network).

 

If this is important and you want this resolved quickly, you should open a TAC case.  There could be a number of things at play, here.

Re: Random Drops For Whole Site

Mobility Master is running on Virtual Machines


The Mobility Devices are on site and 7005 Aruba Controllers 2 of them terminatiing only 10 APS and also around 200 clients - should be sufficient from my calculations 


I think the usage you are referring to is the 90% AP usage set in the threshold list: Aug 14 11:01:46 :399838:  <3556> <WARN> |stm|  Resource 'Total APs' has exceeded  80%  threshold (actual:90%).


How do I check the usage or capacity of the device?
