ACS disconnects network devices randomly

I've got a strange situation where our ACS seems to be disconnecting network devices periodically.  Some of the logs make me thinking there's an issue w/ our AD setup, others point to runtime issues w/ in the ACS.  Typically its just a quick drop and the other ACS picks up the load, but it seems to be happening more often.

Anyone have any idea where I should start on this one?

Unless you are using the COA feature, which requires and advanced license type on ACS, ACS can not disconnect users, there must be an attribute like the session-timeout attribute. or a port level reauthentication configuration.

Can you please describe your issue a little bit deeper and how you think ACS is the reason.

Also is this for wired or wireless users?

Tarik,

Thanks for the reply..  I meant to say that the ACS is disconnecting from the Wireless Controller's and Switches randomly.. not the clients. 

We often see the Wireless controllers deactivating and reactivating the ACS's randomly throughout the day.

It seems that today this has increased quite a bit.

Is this ACS a virtual machine or an appliance. How many users do you estimate are authenticating via radius/tacacs?

Thanks,

Its a VM running on Windows.. 5.2 patch lvl 7.

Tacacs normaly runs slim,, w/ a large config capture of 200ish devices every 4 hours.

Radius deals with approx 7000 devices.. our reauth is set fairly high.. so the auth levels should be low most of the day except for wireless users.

Today the ACS (pair) handled 60,000 radius requests and 6500 tacacs requests

Are you using eap-tls or PEAP, does the box usually drop off when users are jumping back into the network. also for you wireless are you using the default session timers? Check the advanced section in the WLAN configuration to see what this is set to.

Thanks,

We are using both EAP-TLS (Primarily for the wireless controllers)  <-- This is where we saw the ACS timing out more often.. I increased the wireless controller timeout from 2 sec to 5 sec yesterday.. see if that helps..  Not sure if users are actually getting dropped off or not.. What i'm seeing is the controller deactivating and reactivating the ACS radius servers because it wasn't getting a response.

We've often been seeing radius calls taking up to 3-4 seconds.. which we're being told is expected after opening a case.

We are using PEAP for our wired (Primarily switch based radius calls) <-- these rarely get knocked off, but it happens enough to warrant a look, where the switch will identify a radius (acs) as dead in the middle of the day.  The dot1x params on these switches are set to 5 seconds, so I'm assuming this is happening when the ACS is getting busy.. But this really shouldn't be happening with the load we are running,, Thats why i'm trying to investigate if there is another issue somewhere.

Jacob,

Are you performing the binary check against AD for EAP-TLS users? Take a look at the following guide with respect to authentications per second.

http://www.cisco.com/en/US/docs/net_mgmt/cisco_secure_access_control_system/5.2/migration/guide/Migration_Deploy.html#wp1054828

Typically the NAD (WLC or switch) will mark a server dead after a threshold (which you address by extending the timeout for the radius server), it seems with the metrics you provided that you may need to consider reviewing your busiest time, and your wireless session timers as a whole. Make a decision to see if the both ACS can handle the amount of work that is presented at the busiest intervals.

Thanks,
