Hi,
How to detect (via snmp - the best way) interfaces (on cisco catalyst
switch) connected PC with enabled WakeOnLan?
PC is turned off, interface is up due WakeOnLan on PC.

Kesy,

That's quite difficult to do. Without actually waking up the PC
you have a quite hard time distinguishing the WakeOnLan case from the
case of a machine that is not presently active on the network
and which is refusing to talk to you.

I agree, considering to the switch it is just a mac, you would need
some kind of wakeonlan discovery tool, as a switch or router would
most likely have no idea the services that are available on a NIC
connected to a port, other than mac/IP depending on its status.
