Dear Support all,
I would just like to know if there is any specification document or comments.
The test is below, Firstly I have checked the IEEE802.1X auth user then disable Windows7 NIC setting but
Interface L1 connect keeps up. After that the C841M always show the output.
C841M#sh authentication sessions
Interface MAC Address Method Domain Status Session ID
Gi0/0 0000.0000.5555 dot1x DATA Authz Success C0A801FE0000002F00FAEC88
*Disable Windows NIC setting.

C841M#sh ip int brief | in up
GigabitEthernet0/0 unassigned YES unset up down
Compared with Cat2960S it is same so I think this is normal behaviour but I can not fine out any URL.
