Figure 15: Super VLAN Ring Topology Example
Configuring Switch 1:
1.
Enable MSTP and MSTP fast ring:
Switch1
#
configure terminal
Switch1
(config)#
protocol
Switch1
(cfg protocol)#
mstp enable
Switch1
(cfg protocol)#
mstp fast-ring enable
2.
Configure Switch 1 as MSTP Root. Set the bridge priority for MST instance
0 to zero:
Switch1
(cfg protocol)#
mstp 0 priority 0
Switch1
(cfg protocol)#
exit
3.
Configure the ring interfaces as Super-VLAN ports:
Switch1
(config)#
interface 1/1/1
Switch1
(config-if 1/1/1)#
super-vlan 1/1/10
Switch1
(config-if 1/1/1)#
interface 1/1/2
Switch1
(config-if 1/1/2)#
super-vlan 1/1/10
4. Display the Super VLAN configuration:
Switch1
#
show
super-vlan
=====================================================================
User Interface | Super VLAN Type | Uplink
-----------------+-----------------+---------------------------------
1/1/1 | regular | 1/1/10
1/1/2 | regular | 1/1/10
Configuring Switch 2:
1.
Enable MSTP and MSTP fast ring:
Switch2
#
configure terminal
Switch2
(config)#
protocol
Switch2
(cfg protocol)#
mstp enable
Switch2
(cfg protocol)#
mstp fast-ring enable
2.
Configure Super-VLAN on the user interface 1/1/10:
Switch2
(config)#
interface 1/1/10
Switch2
(config-if 1/1/10)#
super-vlan ring-topology 1/1/1 1/1/2
3.
Display the Super VLAN configuration:
Switch2
#
show
super-vlan
=====================================================================
User Interface | Super VLAN Type | Uplink
-----------------+-----------------+---------------------------------
1/1/10 | ring-topology | 1/1/1 (active), 1/1/2
Configuring Switch 3:
