S9700 Core Routing Switch
Configuration Guide - SPU
Step 3 Run:
load-balance probe probe-name icmp
An ICMP probe is created and the ICMP 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.
By default, an ICMP probe is not configured.
Step 4 (Optional) Run:
description description
The probe description is configured.
By default, a probe does not have description.
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 link. 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
The timeout interval of a probe is set.
The timeout interval of a probe must be smaller than the probing interval of a probe and the
interval for a probe to detect that a server member is Down.
By default, the timeout interval of a probe is 10s.
Step 7 (Optional) Run:
retry-count times
The retry count of a probe is set when a link member is in Up state.
By default, The retry count of a probe is 3 when a link member is in Up state.
Step 8 (Optional) Run:
fail-interval interval
The interval for a probe to detect that a link member is Down is set.
After the link becomes invalid, the SPU sends probing packets at this interval to detect link
recovery. This interval must be greater than the timeout interval of a probe.
By default, the interval for a probe to detect that a link member is Down is 60s.

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 has been created.
l A probe does not send probing packets if the specified interface is not configured with an IP address.
