I currently have 2 3com switches, a 3848 and a 4200G, that are in different buildings connected via fibre. I would like to setup 2 different VLAN's that span the two different switches. The reason for this is that I would like to have a customer drop-in network that I can allow customers and guests to connect to the internet but not our network but we only have internet in one building. I have setup a second VLAN on both switches and assigned a couple ports to them. My question is, how can I get the ports setup as VLAN 2 on switch 1 to talk to ports setup as VLAN 2 on switch 2? Right now I can not even ping between them. I have read some information on Trunking but I am very new to 3Com switches and want to make sure I get it right the first time. Thanks in advance.
