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
jitter Jitter is a variation in the delay of received packets, which can be worsened by
network congestion, improper queueing and configuration errors. The WAN
health-check feature measures jitter on the connection to the remote host by
sending and measuring packets at fixed intervals. Jitter measurements are only
available if the health-check feature is set to send UDP packets.
mode ping|udp Enable this feature by issuing the mode command and choosing the type of probe
packets to be sent, ping or udp.
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 delay of
ping responses.
Examples
The following commands enable this feature, and reduce the default probe frequency interval and probe burst
size.
