Per-VLAN Spanning Tree Plus (PVST+) |
451
extend system-id
Use Extend System ID to augment the Bridge ID with a VLAN ID so that PVST+ differentiate
between BPDUs for each VLAN. If for some reason a VLAN receives a BPDU meant for another
VLAN, PVST+ will then not detect a loop, and both ports can remain in forwarding state.
