Chapter 7 Reliability Configuration

configuring ULPP needs to send the flush packets through the port which is switched to

Forwarding state, and update MAC address tables and ARP tables of other devices in the

network. ULPP respectively uses two kinds of flush packets to update the entries: the

updated packets of MAC address and the deleted packets of ARP.

For making use of the bandwidth resource enough, ULPP can implement VLAN load

balance through the configuration. As the picture illustrated, SwitchA configures two ULPP

groups: portA1 is the master port and portA2 is the slave port in group1, portA2 is the

master port and portA1 is the slave port in group2, the VLANs are protected by group1

and group2, they are 1-100 and 101-200. Here both portA1 and portA2 at the forwarding

state, the master port and the slave port mutually backup, and respectively forward the

packets of the different VLAN ranges. When portA1 has the problem, the traffic of VLAN

1-200 are forwarded by portA2. After this, when portA1 is recovering the normal state,

portA2 forwards the data of VLAN 101-200 sequentially, but the data of VLAN 1-100 is

switched to portA1 to forward.
