Chapter 6 Interfaces

ZyWALL (ZLD) CLI Reference Guide

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

interface Commands: Ping Check

show ping-check [interface_name | status]

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.

[no] connectivity-check continuous-log 

activate

Use this command to have the ZyWALL logs connectivity check 
result continuously. The no command disables the setting.

show connectivity-check continuous-log status

Displays the continuous log setting about connectivity check.

interface interface_name

Enters sub-command mode.

[no] ping-check activate

Enables ping check for the specified interface. The 

no

 command 

disables ping check for the specified interface.

ping-check {domain_name | ip | default-

gateway}

Specifies what the ZyWALL pings for the ping check; you can 
specify a fully-qualified domain name, IP address, or the default 
gateway for the interface.

ping-check {domain_name | ip | default-

gateway} period <5..30>

Specifies what the ZyWALL pings for the ping check and sets the 
number of seconds between each ping check.

ping-check {domain_name | ip | default-

gateway} timeout <1..10>

Specifies what the ZyWALL pings for the ping check and sets the 
number of seconds the ZyWALL waits for a response.

ping-check {domain_name | ip | default-

gateway} fail-tolerance <1..10>

Specifies what the ZyWALL pings for the ping check and sets the 
number of times the ZyWALL times out before it stops routing 
through the specified interface.

ping-check {domain_name | ip | default-

gateway} method {icmp | tcp}

Sets how the ZyWALL 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. 

ping-check {domain_name | ip | default-

gateway} port <1..65535>

Specifies the port number to use for a TCP connectivity check.
