Basic VLAN question.

If you have two switches that both have VLAN 7 on them, then the two are *different* VLANs unless there is a tagged VLAN 7 trunk path between the relevant ports.

For example, if ports 1, 2, 21, and 22 are all marked as being in VLAN 7, and you have bridging (or IRB) set up between ports 1 and 2 (e.g., bridge group 30) and between 21 and 22 (e.g., bridge group 74), but there is no bridge between the two groups, then they are effectively

-different- VLAN 7s... except when the switch gets them confused for Spanning Tree or ARP table purposes.

Simply having two switch with ports in VLAN 7 is not enough to integrate VLAN 7 between the two switches: the trunk that connects the switches must carry VLAN 7. (If this were not the case, then the VLAN 7 that I create here would be the same VLAN 7 that you create there.)

Hi

Assuming that your current setup (trunking btw switches )is working for vlan7 on different switches then Yes you just have to associate the port to vlan 7 .
