Description
This command configures WAN health-check ping-probes for measuring WAN availability and latency on
branch controller uplinks.
Syntax
Parameter Description
burst-size <size> Number of probes to be sent during the probe frequency interval defined by the
frequency parameter of this profile.
Range: 1-16, Default 5
frequency
<frequency>
Probe interval, in seconds. The WAN health-check feature sends the number of
probes defined by the burst-size parameter during each frequency interval defined
by this frequency parameter.
Range: 10-65535, Default 10
mode ping Enable this feature by issuing the mode ping command. Ping is the only mode
currently supported by this feature.
no Remove or negate any configured parameter
retries <count> Number of times the controller attempts to resend a probe.
Range: 1-255, Default 5
Usage Guidelines
The health-check feature uses ping-probes to check reachability and latency from the branch controller to
datacenter though each of the branch controller's WAN uplinks. Latency is calculated based on the round-trip
time (RTT) of ping responses. Ping settings are configured globally using the ip probe default command.
Examples
The following commands enable this feature, and reduce the default probe frequency interval and probe burst
size.
