Generate Ping packets on this interface
Enabling this option displays the parameters for enabling auto-pings to be transmitted from
this interface. These pings can be monitored by the interface auto-pings were enabled on and
in the event of no ping reply, the interface can be taken out of service for a specified amount
of time, before allowing the interface to be used again. Another option is to enable auto-pings
on this interface and let the firewall handle taking the interface out of service in the event of a
failure. Both methods are explained in Application Notes on our Technical Support
Documents web page.
Send n byte pings to IP host a.b.c.d every h hrs m mins s seconds
For this setting, n specifies the payload size of a ping packet when used with the auto ping
feature. Leaving this parameter blank will use the default value. The address a.b.c.d specifies
the destination IP address for auto-ping ICMP echo request. The values h, m and s specifies
how often the router will transmit Auto-ping packets to the specified destination in (h) Hours,
(m) Minutes and (s) Seconds.
Switch to sending pings to IP host a.b.c.d after n failures
For this setting, a.b.c.d specifies an alternative destination IP address for the auto-ping ICMP
echo request to be sent to, should the main IP address specified in the parameter above fail to
respond. This allows the router to double check there is a problem with the connection and
not just with the remote device not responding. The value n specifies the number pings that
need to fail before the 2nd IP address is checked. The extra IP address check is only enabled if
this parameter is set to something other than 0.
Only send Pings when this Ethernet interface is “In Service"
If this parameter is enabled, ICMP echo requests will only be sent from this interface when it is
in service. The default setting is disabled, ICMP echo requests are sent when the interface is in
service and out of service.
Take this interface "Out of Service" after receiving no responses for s seconds
The length of time, in seconds, before a route will be designated as being out of service if
there has been no response to ANY of the ICMP echo requests during that time period.
Keep this interface out of service for s seconds
The length of time, in seconds, for which any routes using this Ethernet interface will be held
out of service after a ping failure is detected.
