• Disable the spanning tree feature and RRPP on the ports that you want to add to the smart link group,
and make sure the ports are not member ports of any aggregation group.
NOTE:
A
loop may occur on the network during the time when the spanning tree feature is disabled but Smart Lin

has not yet taken effect on a port.
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. (In PVST mode,
the system automatically maps VLANs to MSTIs.) For more information about MSTI and PVST, see Layer
2—LAN Switching Configuration Guide.
To configure the protected VLANs for a smart link group:
