Figure 7-11 ULPP typical example2

ULPP can implement the VLAN-based load balance. As the picture illustrated,

SwitchA configures 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 different 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.
