I currently have a stack of SMC 8748M switches (total of 4). I'm using 2 VLAN on it (1 and 2). What I have so far :

  • a trunk between SMC and Dell switches, (2 ports trunk).

When I put a single port on a vLAN #1 on Dell switch, it is not recognized as the same VLAN #1 as on the SMC switches.

I have seen somewhere to enable GVRP, but I am not sure..

I would like to know how to do that on both side.

Regards, David.

On the bonded ports, set vLAN 1 and 2 to tagged (on both units).

Also, Check that the actual VLAN id is the same. Names of a VLAN don't necessarily correspond to the actual VLAN id (tag). – TheCleaner Jul 20 '11 at 17:24
I have checked both side vlan's id and everything fits.. I am also wondering if I should set my normal ports (not trunked ports) to tagged or untagged. Also, when everything is default (on vlan 1) it ping well, but as soon as I put 2 unit (1 on SMC's and 2nd on Dell's) on VLAN #2, they don't ping eachother. – David Jul 20 '11 at 18:10
The "other" ports should be untagged. Only trunk ports should be tagged (for most configurations) – Chris S Jul 20 '11 at 18:51
