This configuration shows how to configure the three instances of STGs on the
switches A, B, C, and D illustrated in Figure 14 on page
Because VASA is enabled by default, each new VLAN is automatically assigned its
own STG.
RS 8264CS(config)# spanning-tree mode pvrst
Note: PVRST is the default mode on the G8264CS. This step is not required unless
the STP mode has been previously changed, and is shown here merely as an
example of manual configuration.
a. Enable VLAN 2 and VLAN 3.
RS 8264CS(config)# vlan 2
RS 8264CS(config-vlan)# exit
RS 8264CS(config)# vlan 3
RS 8264CS(config-vlan)# exit
If VASA is disabled, enter the following commands:
RS 8264CS(config)# spanning-tree stp 2 vlan 2
RS 8264CS(config)# spanning-tree stp 3 vlan 3
b. Add port 17 to VLAN 2, port 18 to VLAN 3.
RS 8264CS(config)# interface port 17
RS 8264CS(config-if)# switchport mode trunk
RS 8264CS(config-if)# switchport trunk allowed vlan 2
RS 8264CS(config-if)# exit
RS 8264CS(config)# interface port 18
RS 8264CS(config-if)# switchport mode trunk
RS 8264CS(config-if)# switchport trunk allowed vlan 3
RS 8264CS(config-if)# exit
VLAN 2 and VLAN 3 are removed from STG 1.
Note: In PVRST mode, each instance of STG is enabled by default.
