Hello,
I have 2x 260gs and I made a config like this:
Switch 1:
port 2: VLAN 10
port 3: VLAN 20
port 4: VLAN 30
port 5: trunk port to Switch 2(carries VLAN 1,10,20,30)
Switch 2:
port 1: trunk port to Switch 1(carries VLAN 1,10,20,30)
port 2: VLAN 10
port 3: VLAN 20
port 4: VLAN 30
Next I Mirrored the Ingress and Egress traffic form port 5 (Switch 1) to port 1(Switch 1). There’s a PC where a capture the packets via wireshark. Anythink seems to be working but, I dont get to see any tagged frames in wireshark. Did I do anythink wrong? The broadcast domains are separeted for each VLAN so it works I suppose… but still, the tagged packets don’t occur in the trunk port 
Any ideas why?
