How can the Cisco 3550 be configured to sent the Vlan tag in the frame to the device attached to it's ports.

I use sniffer program to check vlan. But I suspect the 3550 is sending the frames without the vlan-tags. So sniffer program does not show Vlan.

Think I found an "answer" myself.
Attach "sniffing" PC to a trunk port and there you go!
