Creating a VLAN

￿When you create a VLAN, that VLAN automatically belongs to STG 1, the default STG. To place the VLAN in a different STG, follow these steps:

￿Create the VLAN.

￿Add the VLAN to an existing STG.

The VLAN is automatically removed from its old STG before being placed into the new STG.

￿Each VLANs must be contained within a single STG; a VLAN cannot span multiple STGs. By confining VLANs within a single STG, you avoid problems with Spanning Tree blocking ports and causing a loss of connectivity within the VLAN. When a VLAN spans multiple switches, it is recommended that the VLAN remain within the same STG (be assigned the same STG ID) across all the switches.

￿If ports are tagged, all trunked ports can belong to multiple STGs.

￿A port cannot be directly added to an STG. The port must first be added to a VLAN, and that VLAN added to the desired STG.

Rules for VLAN Tagged Ports

￿Tagged ports can belong to more than one STG, but untagged ports can belong to only one STG.

￿When a tagged port belongs to more than one STG, the egress BPDUs are tagged to distinguish the BPDUs of one STG from those of another STG.
