Chapter 6 Interfaces
6.2.3 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 NXC stops routing to the gateway. The NXC
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.
Displays information about ping check settings for
the specified interface or for all interfaces.
Use this command to have the NXC logs
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
no
command disables ping check for the specified
interface.
Specifies what the NXC 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 NXC pings for the ping check
and sets the number of seconds between each
ping check.
Specifies what the NXC pings for the ping check
and sets the number of seconds the NXC waits for
a response.
Specifies what the NXC pings for the ping check
and sets the number of times the NXC times out
before it stops routing through the specified
interface.
Sets how the NXC 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
