S9700 Core Routing Switch
Configuration Guide - SPU
about server instances serverc and serverd, indicating that user packets are switched to
servergroup2 after Server A of servergroup1 is faulty. The packets are load balanced between
Server C and Server D according to a ratio.
[SPU] display load-balance group name servergroup1 member name servera verbose
[SPU] display load-balance group name servergroup1 member name serverb verbose
[SPU] display load-balance group name servergroup2 member name serverc verbose
[SPU] display load-balance group name servergroup2 member name serverd verbose
# Recover the link between the SPU and Server A, simulate the internal network user at
10.10.10.2 to access the virtual IP address 20.20.20.2/24, and then view related information
about servera, serverb, serverc, and serverd on SPUA. You can view that packet statistics
about server instances servera and serverb increase, whereas packet statistics about server
instances serverc and serverd do not increase. That is, user packets are switched back to
servergroup1 after Server A of servergroup1 is recovered, and are load balanced between
Server A and Server B according to a ratio.
