Add port 8 to VLAN 3. Ports 1 and 2 are by default in VLAN 1 assigned to STG 1.
CN4093(config)# vlan 3
CN4093(configvlan)# stg 3
CN4093(configvlan)# exit
CN4093(config)# interface port 8
CN4093(configif)# switchport mode trunk
CN4093(configif)# exit
If VASA is disabled, enter the following command:
CN4093(config)# spanningtree stp 3 vlan 3
VLAN 3 is automatically removed from STG 1. By default VLAN 1 remains in STG
1.
Switch D does not require any special configuration for multiple Spanning Trees.
Switch D uses default STG 1 only.
