Hi, just got brand new 3945E with following config:

All Gigabit interfaces are plugged into trunk ports on swith. There is a traffic in Vlan1, but there is no IP enabled interfaces in that vlan, furthermore arp-proxy and broadcast forwarding explicitly turned off and here what i get:
#sho ip flow top-talkers

8 of 200 top talkers shown. 8 flows processed.
Why the hell broadcast gets forwarded? did i miss something?
