ip probe health-check ip probe health-check burst-size frequency mode ping|udp jitter no retries Description This command configures WAN health-check ping-probes for measuring WAN availability and latency on branch controller uplinks. Syntax Parameter burst-size Description 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 jitter 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 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 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.
