S9700 Core Routing Switch
Configuration Guide - SPU
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
load-balance ip interface interface-type interface-number
The IP address of a sub-interface is obtained and used as the source IP address of probing packets
of a probe.
The interface type can be XGE sub-interface, loopback interface, or Eth-Trunk sub-interface.
Step 3 Run:
load-balance probe probe-name [ http | icmp | udp | tcp ]
A probe is created or the probe view is displayed.
When creating a probe, you must specify the probe type. When you enter the view of the created
probe, you can choose not to specify the probe type.
Up to 1024 probes can be created, including ICMP probes, TCP probes, UDP probes, and HTTP
probes.
By default, no probe is configured.
Step 4 (Optional) Run:
description description
The description of the probe is configured.
By default, no description is configured for a probe.
Step 5 (Optional) Run:
interval interval
The probing interval of a probe is set.
The probing interval of a probe indicates the interval for sending probing packets to detect the
health status of a server. The probing interval of a probe must be greater than the timeout interval
of a probe.
By default, the probing interval of a probe is 15s.
Step 6 (Optional) Run:
time-out time-out
Issue 01 (2012-03-15)
be failed. Then the SPU determines whether to set the server to Down according to the
probe mode set on the server group.
NOTE
When the probe mode is AND, the SPU sets a server to Down only if the probing of all probes fails. When
the probe mode is OR, the SPU sets a server to Down if the probing of a probe fails.
NOTE
l When running the load-balance ip interface command, you can select the specified interface only if
an XGE sub-interface, a loopback interface, or an Eth-Trunk sub-interface is specified.
l A probe does not send probing packets if the specified interface is not configured with an IP address.
