Configuring protected VLANs for a smart link group
You can configure protected VLANs for a smart link group by referencing MSTIs. Before configuring the
protected VLANs, configure the mappings between MSTIs and the VLANs to be protected (a device
working in PVST mode automatically maps VLANs to MSTIs). For more information about MSTIs and
PVST, see Layer 2—LAN Switching Configuration Guide.
To configure the protected VLANs for a smart link group:
