How can I setup a VLAN between two different 3Com switches

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.

Dear dhigh22 ,

In general when you want to connect between 2 VLAN you should do the following :
1- create VLANs on each Switch
note : if you configure your Switch with VTP configuration you just need to create VLANs in core switch ( switch with server mode ) and this swith (server mode ) will publish your configuration automatically to all switch)

2-configure the Uplink ports ( fiber ports in your case ) as trunk
port with encapsulation 802.1q

Trunk : Check this link maybe helpful

3- after configure Trunk ports you should do port assignmnet
for example : PC1 connected to Port 1 in switch and this PC1
should be in VLAN 2 ( for example )
enter to switch config mode and make ports assignment to port1 (PC1 ) to be member in VLAn2

4- check this website :

Dear dhigh22 ,
when you configure your switches successfully  you should do this
 
PC1 ( VLAN2 ) in switch 1 can ping PC1(VLAN2) in switch 2
PC2 ( VLAN2 ) in switch 1 can ping PC2(VLAN2) in switch 2

Good Luck

Muhammed-Rummaneh, I have looked at your posts but I have read most of the information you proposed already.  I need specific instructions for these two switches as I am unable to figure out how to setup the Fibre ports as trunks.  Also, do I need to setup a VLAN interface for each VLAN?  I have most of the theoretical information down as far as VLANS go but I don't know how to implement in a real-world environment with the hardware I have here.  Sorry, very new to VLAN's.

Thank you Muhammed-Rummaneh,

I had a look through the command list you sent and it does give a bunch of the proper commands I am sure.  However, I was hoping that I would be able to do most of this through the web interface that comes with the 3COM swtiches.  I was able to do all of the VLAN setup and such via the web interface and thought I should be able to get the switches working together as well.

One thing though is that the firmware on my switches is a couple of versions old.  I would prefer not having to update them but if that is nessesary to get this working I probably will do it.

The thing with the web interface on the current version of the software that I have I am unable to find anything relating to 802.1Q anywhere?

Thanks again,
dhigh22
