User re-authentication on same AP/different APs before the session/idle timeout

Qing Yu · ‎09-19-2010

I am facing an issue which user needs to re-authenticate before the session/idle timeout.

Here are the information

WLCx1

Model - 4402
Software Version - 6.0.196.0
Emergency Image Version - 5.2.157.0

APx30

Model - 1252AG
Boot Version 12.4.10.0
IOS Version 12.4(21a)JHA

Time-out settings

Session Time-out :43200
Idle Time-out: 43200

Trap Log

Mon Sep 20 09:36:46 2010 User Username 1 logged in. Client MAC:00:21:63:bf:d3:d7, Client IP:10.90.224.19, AP MAC:00:22:90:5e:79:60, AP Name:AP0022.905d.70d4

Mon Sep 20 08:41:45 2010 User Username 1 logged in. Client MAC:00:21:63:bf:d3:d7, Client IP:10.90.224.19, AP MAC:00:23:04:c9:58:b0, AP Name:AP0023.04b9.039a
Mon Sep 20 08:35:32 2010 User Username 1 logged in. Client MAC:00:21:63:bf:d3:d7, Client IP:10.90.224.19, AP MAC:00:23:04:c9:58:b0, AP Name:AP0023.04b9.039a

Note: I replaced the real user name with "Username 1"

The reauthetication issue happened on the same AP as well as different APs.

I've tried different software versions from V4 to V6 and the same problem happens.

Please let me know your suggestions.

Thanks

You'd have to run debug client to see what is going on. 99.9999% when the client is reauthing on a roam, it has to do with the keying method, on the supplicant.

Thanks Stephen,

I've turned on the client debug with the following debug flags enabled:

dhcp packet enabled.
dot11 mobile enabled.
dot11 state enabled
dot1x events enabled.
dot1x states enabled.
mobility handoff enabled.
pem events enabled.
pem state enabled.
CCKM client debug enabled.

I received the message "No Mobility groupcast sent, member count 0" right after I turned on mobility handoff enabled flag.

There are no other debug messages available yet.
