[SWA] stp region-configuration
[SWA-mst-region] instance 0 vlan 1 to 100[SWA-mst-region] instance 2 vlan 101 to 200[SWA] smart-link group 1
[SWA-smlk-group1 ] protected-vlan reference-instance 0 [SWA-smlk-group1] port gigabitethernet 2/0/1 master[SWA-smlk-group1 ] port gigabitethernet 2/0/2 slave [SWA] smart-link group 2
