Description

This command configures WAN health-check ping-probes for measuring WAN availability and latency onmanaged deviceup-links. The health-check feature uses ping-probes to check reachability and latency from themanaged deviceto data center though each of themanaged device's WAN up-links. Latency is calculated based on the delay of ping responses.

Parameter	Description
burst-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
频率<秒>	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:10-3600 Default:10
jitter	Jitter is a variation in the delay of received packets, which can be worsened by network congestion, improper queuing 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,pingorudp.
no	Remove or negate any configured parameter.
retries	Number of times themanaged deviceattempts to resend a probe. Range:1-255 Default:3
