In my lab I have a non Cisco gateway (Zyxel VSG-1200) with Cisco ME3400 connected to its LAN port and then I have a PC off of ME3400. I am having issues with VLAN's and I'm trying to see why VLAN's won't work with that specific gateway. VLAN's work fine when I use different vendor (such as Cisco and other ones) Is there any way to capture traffic between GTW and ME3400 to see what is going on? I'm having a feeling that VSG is not tagging packets back into the LAN.
Very simple setup
Thanks in advance
