Figure 59.4: ULPP typical example 2
ULPP can implement the VLAN-based load balance. As the picture illustrated, SwitchA config-
ures two ULPP groups: port E1/0/1 is the master port and port 1/0/2 is the slave port in group1, port
1/0/2 is the master port and port 1/0/1 is the slave port in group2. The VLANs protected by group1
are 1-100 and by group2 are 101-200. Here both port E1/0/1 and port E1/0/2 at the forwarding
state, the master port and the slave port mutually backup, respectively forward the packets of dif-
ferent VLAN ranges. When port E1/0/1 has the problem, the traffic of VLAN 1-200 are forwarded
by port E1/0/2. When port E1/0/1 is recovering the normal state, still port E1/0/2 forwards the data
of VLAN 101-200, the data of VLAN 1-100 are switched to port E1/0/1 to forward.
SwitchA configuration task list:
Switch(Config)#spanning-tree mst configuration
Switch(Config-Mstp-Region)#instance 1 vlan 1-100
Switch(Config-Mstp-Region)#instance 2 vlan 101-200
Switch(Config-Mstp-Region)#exit
Switch(Config)#ulpp group 1
Switch(ulpp-group-1)#protect vlan-reference-instance 1
Switch(ulpp-group-1)#preemption mode
Switch(ulpp-group-1)#exit
Switch(Config)#ulpp group 2
Switch(ulpp-group-2)#protect vlan-reference-instance 2
