Connectivity Check (Ping-Check) Commands - ZyXEL Communications ZYWALL USG Series Reference Manual

13.2.7 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 / USG stops routing to the gateway. The ZyWALL / USG resumes
routing to the gateway the first time the gateway passes the connectivity check.

DESCRIPTION
Displays information about ping check settings for the specified
interface or for all interfaces.
status: displays the current connectivity check status for any
interfaces upon which it is activated.
Use this command to have the ZyWALL / USG log connectivity
check result continuously. The no command disables the setting.
Displays the continuous log setting about connectivity check.
Enters sub-command mode.
Enables ping check for the specified interface. The
disables ping check for the specified interface.
Specifies what the ZyWALL / USG pings for the ping check; you can
specify a fully-qualified domain name, IP address, or the default
gateway for the interface.
Specifies what the ZyWALL / USG pings for the ping check and sets
the number of seconds between each ping check.
Specifies what the ZyWALL / USG pings for the ping check and sets
the number of seconds the ZyWALL / USG waits for a response.
Specifies what the ZyWALL / USG pings for the ping check and sets
the number of times the ZyWALL / USG times out before it stops
routing through the specified interface.
Sets how the ZyWALL / USG checks the connection to the gateway.
icmp: ping the gateway you specify to make sure it is still available.
tcp: perform a TCP handshake with the gateway you specify to
make sure it is still available.
Specifies the port number to use for a TCP connectivity check.
