Hi, I have three wireless bridge connections goes to a 3com Switch (baseline 2226Plus, It supports VLAN). From this switch a connection goes to a cisco router. The above 3 bridges are from different networks of remote offices. I need to know how to create VLAN in this switch. So far, I have done this:
Port 1-4 assigned to VLAN ID 9 (intented for Bridge 1),
Port 5-8 assigned to VLAN ID 10 (intended for Bridge 2) .
Port 9-12 assigned to VLAN ID 11 (intended for bridge 3)
The remaining ports can be used to connected to the router. Now I want to know how to get the above 3 bridges communicate with the router port. I am confused with the tagged/untagged term. Please help where should i use tag and untag until fulfil this scenario.
Thanks for your help..
