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
Table 21 interface Commands: Ping Check
COMMAND DESCRIPTION
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.
show ping-check [interface_name] Displays information about ping check settings for
the specified interface or for all interfaces.
[no] connectivity-check continuous-log
activate
Use this command to have the ZyWALL logs
connectivity check result continously. 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

name, IP address, or the default gateway for the
interface.
ping-check {domain_name | ip | default-

Specifies what the ZyWALL pings for the ping

ping-check {domain_name | ip | default-
gateway} timeout <1..10>
Specifies what the ZyWALL pings for the ping

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

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
