Setting up 2 VLAN's over fibre backbone
Hi,
I've got a question about setting up VLAN's on 3Com switches.
We've got two locations connected with a fibre backbone. (Both locations use the same subnet). On both locations a 3Com 4228G switch is used.
I want to set up a VLAN for a couple of pc's which are broadcasting quite a bit. I'm thinking about creating a VLAN 2 for these pc's and use the 3Com default VLAN 1 for the other clients. However.....what about my fibre backbone. Do I have to configure these fibre ports to be a member of both VLAN's to let both VLAN's communicate over the backbone? How do I do this?
So in short.....both locations use VLAN 1 and VLAN 2, how do I configure the backbone ports?
Regards,
Aico

Do I only need to configure the fibre ports to use tagging or do I also have to configure all other ports to use tagging?
For example, is it possible to leave all the default ports (normal pc's) in the default VLAN 1 untagged and put the broadcasting pc ports in VLAN 2 untagged and configure all the fibre backbone ports to be a member of both VLAN's tagged?

Yes, just the fibre ports need to be configured as tagged (or trunked). The end user ports are set as members of a paticular VLAN.

Ok, one final question. I think this applies to all uplink ports ( in case of more then two switches ). Am I right? Do all the uplink ports need to be configured as tagged?

Great! Thank you for your help! Points well earned, I would say.
The only other thing to watchout for is that 802.1q has a "native" VLAN. It usually defaults to VLAN1. The catch here is that it must be the same on each end of the trunk.
