Chapter 5 Configuring Ethernet VLAN Trunks
On Switch 2, change the port-VLAN priority for the Group 2 VLANs on Trunk 2 (port 1/2) to the same
Step 12
value you configured for those VLANs on Switch 1 by entering the set spantree portvlanpri command.
Switch_2> (enable) set spantree portvlanpri 1/2 1 40
Port 1/2 vlans 1-39,41-1004 using portpri 32.
Port 1/2 vlans 40 using portpri 1.
Port 1/2 vlans 1005 using portpri 4.
Switch_2> (enable) set spantree portvlanpri 1/2 1 50
Port 1/2 vlans 1-39,41-49,51-1004 using portpri 32.
Port 1/2 vlans 40,50 using portpri 1.
Port 1/2 vlans 1005 using portpri 4.
Switch_2> (enable) set spantree portvlanpri 1/2 1 60
Port 1/2 vlans 1-39,41-49,51-59,61-1004 using portpri 32.
Port 1/2 vlans 40,50,60 using portpri 1.
Port 1/2 vlans 1005 using portpri 4.
Switch_2> (enable)
Note
Step 13 Check the spanning tree port states on Switch 1 by entering the show spantree command. The Group 1
VLANs should forward on Trunk 1 and block on Trunk 2. The Group 2 VLANs should block on Trunk 1
and forward on Trunk 2.

When you have configured the port-VLAN priorities on both ends of the link, the spanning
tree converges to use the new configuration.
