Can you disable WOL on the clients?  Seems like if it was disabled in the
BIOS, the NIC would have no reason to bring up a link when
off/sleeping/hibernating.

Hey guys,

 

Has anyone out there come across a condition where switch ports secured with
802.1x have issues with clients/supplicants that go into hibernate / sleep
mode?

 

We have some clients that are hibernating and as a result the switch is
filling the logs with failed 802.1x authorization attempts. The switch looks
to be trying to authenticate the supplicant but the supplicant is not
responding due to the hibernation status.

 

Is there any way around this other than configuring a hardware supplicant
that is not reliant on the client OS? Doing some reading around I haven't
much info other than the allowing of magic packets out the switch port for
the purpose of WOL.

 

Any advice is greatly appreciated.

 

Thanks,

 

Aaron.
