Figure 7-13 ULSM typical example

The above topology is the typical application environment which is used by ULSM

and ULPP protocol.

ULSM is used to process the port state synchronization, its independent running is

useless, so it usually associates with ULPP protocol to use. In the topology, SwitchA

enables ULPP protocol, it is used to switch the uplink. SwitchB and SwitchC enable ULSM

protocol to monitor whether the uplink is down. If it is down, then ULSM will execute the

down operation for the downlink port to shutdown it, so ULPP protocol of Swtich A

executes the relative operation of the uplink switchover.

SwitchA configuration task list:

Switch(Config)#spanning-tree mst configuration

Switch(Config-Mstp-Region)#instance 1 vlan 1

Switch(Config-Mstp-Region)#exit

Switch(Config)#ulpp group 1

Switch(ulpp-group-1)#protect vlan-reference-instance 1

Switch(ulpp-group-1)#exit

Switch(Config)#interface ethernet 1/0/1

Switch(config-If-Ethernet1/0/1)# ulpp group 1 master

Switch(config-If-Ethernet1/0/1)#exit

Switch(Config)#interface Ethernet 1/0/2

Switch(config-If-Ethernet1/0/2)# ulpp group 1 slave

Switch(config-If-Ethernet1/0/2)#exit

SwitchB configuration task list:

Switch(Config)#ulsm group 1

Switch(Config)#interface ethernet 1/0/1
