Refer to the exhibit. L3SW1 has a spanning-tree priority of 8192 set on VLANs 1, 300, and 301, and these VLANs are configured on and trunked between all switches. Executing the command show spanning-tree blockedports on L2SW5 results in:

L2SW5# show spanning-tree blockedports Name Blocked Interfaces List -------------------- ------------------------------------ VLAN0001 Gi1/1 VLAN0300 Gi1/1 VLAN0301 Gi1/1 An additional VLAN, VLAN302, is defined on all switches and trunked between them. VLAN302 access ports are set up on each of the switches and PLC#1, I/O#1, and the PanelView are attached. You expect the new VLAN to be listed as blocked on interface GigabitEthernet1/1 of L2SW5 but it is not. The three new devices are able to communicate with each other. After executing the same command on all switches you see this output on L2SW4:

L2SW4# show spanning-tree blockedports Name Blocked Interfaces List -------------------- ------------------------------------ VLAN0001 Gi1/2 VLAN0300 Gi1/2 VLAN0301 Gi1/2 Why is VLAN302 forwarding on L2SW5 interface GigabitEthernet 1/1 and L2SW4 interface GigabitEthernet 1/1 and 1/2?
