Quick follow-up:

I have a monitor session on a 1G port listening to vlan2, because I
need to detect new mac addresses with arpwatch and solve possible
conflicts if two customers suddenly use the same IP address.
I turned off the monitoring session, and the port-channel is running fine!

I still need something to listen in vlan2 - what workaround can be done?
