Airwave sticky clients

[ Edited ]

Hi,

 

first post on airheads community.

Im new to this aruba thing. I recently installed Aruba system with mobility controller 7205 and Airwave server.

 

So far everything ran fine.

This morning i noticed somethign weird while looking at the total client graph. 280 clients were supposedly connected all night long, which i'm afraid is not true. It seem to me that some clients "stick" in the db and are considered connected by airwave while they shouldnt.

Did this happen to some of you? how can i fix that, so that my graph shows the real values.

 

See attached screencap for screenshot of the graph.

 

Thanks.

Re: Airwave sticky clients

Do you have a Captive Portal?  Those could be clients that are associated but not logged in.

Hi Joseph,

 

we do not have a captive portal on the wireless network those clients are supposedly connected on.

Re: Airwave sticky clients

In airwave you should run a Daily Client Session Report for that specific period of time with details to see what devices Airwave considers still connected to your network.

Thanks Colin

I did run a Daily client session report, but it just list clients which are still considered connected indeed on that specific time period. It doesnt help resolving the issue though.

Re: Airwave sticky clients

Did you edit the user idle timeout on the controller?  What is the output of "show aaa timers"?

Re: Airwave sticky clients

the results of show aaa timers is 

Global User idle timeout = 300 seconds
Auth Server dead time = 10 minutes
Logon user lifetime = 5 minutes
User Interim stats frequency = 600 seconds

i changed the user idle timeout only in my captive portal settings (authentication / L3 auth / captive portal auth / portal), but those portal are not used on this wireless.

 

If i connect to the controller interface the dashboard shows the correct number of clients.

Re: Airwave sticky clients

I am out of guesses. You should open a TAC case to find out why.

Re: Airwave sticky clients

How is AirWave getting data from the controller?  If it's SNMP, it's possible that we never saw the client de-auth.  If it's AMON (this is the preferred way of collecting data from Aruba controllers), then need to make sure the AMP is preferring AMON over SNMP on AMP Setup, and then verify that the proper message types are configured:

 

from controller:

show mgmt-servers

show mgmt-server profile (profile of the server entry from above command output)

at minimum, should have stats-enable, sessions-enable, monitored-info-enable, and misc-enable

Re: Airwave sticky clients

AMON is enabled and prefered over SNMP.

 

show mgmt-server
