for re authentication i need to restart PC/ Laptop or unplug and replug lan cable from it!

but before restartiong i am able to ping all DNS, DHCP, OCS, everything....

below is the interface configuration

sh running-config interface gigabitEthernet 3/0/19
Building configuration...

When the machine is in the state can you issue a "show authentication sess interface gig 3/0/19" you should be able to see what state the client is in. Also do you see any events in the monitoring and reporting section in ISE at this time. I have seen that when a machine is locked this port stays up and you do not have to reauthenticate.

thanks,

debug authentication all

What happens if you restart the Wired Autoconfiguration service?

Hi Tabish,

I have made below changes on interface which are shown in bold letters!

In my configuration

authentication order was wrong

and you can give reauthenticatin timer reauthenticate through interface as well as through Server

In my configuration I have configured it to the ISE server.

authentication control-direction in

authentication event fail action next-method

authentication event server alive action reinitialize

authentication host-mode multi-auth

authentication open

authentication order dot1x mab

authentication priority dot1x mab

authentication port-control auto

authentication periodic

authentication timer reauthenticate server

authentication violation restrict

mab

mls qos trust dscp

dot1x pae authenticator

dot1x timeout tx-period 10

if you need any more information please reply back and if possible send me interface configuration.

Thanks,

Sachin

Authentication order:

switch(config-if)# authentication order [dot1x | mab] | {webauth}
