6.2.6 Connectivity Check (Ping-check) Commands
Use these commands to have an interface regularly check the connection to the gateway you
specified to make sure it is still available. You specify how often the interface checks the connection,
how long to wait for a response before the attempt is a failure, and how many consecutive failures
are required before the ZyWALL stops routing to the gateway. The ZyWALL resumes routing to the
gateway the first time the gateway passes the connectivity check.
This table lists the ping-check commands

show connectivity-check continuous-log status Displays the continuous log setting about connectivity check.
interface interface_name Enters sub-command mode.
