Generate Ping packets on this interface
This section relates to monitoring pings which can be sent from the mobile interface. For more
details, refer to
enabled, displays the following parameters:
Send n byte pings to IP host a.b.c.d every h hrs m mins s secs
If this parameter is set, the router automatically generates a ping of n size to the IP host
specified (IP address or hostname) at the interval specified. Deleting the IP host value disables
the monitoring ping facility.
This parameter in conjunction with Reset the link if no response is received within s
seconds, configures the router to use a back-up interface automatically should there be a
problem with this interface.
Note The n parameter specifies the ping size when using monitoring ping feature. The size
indicates how large the ICMP packet should be excluding the size of the IP header.
Send pings every h hrs m mins s secs if ping responses are not being received
When set, the router uses this value as the interval to ping at when more than one ping
request sent out the PPP interface is outstanding. This should be set to a shorter interval than
the above ping request interval so that the router may more quickly react to a broken PPP link.
Switch to sending pings to IP host a.b.c.d after n failures
Allows a for more reliable problem detection before fail over occurs by testing connectivity to 2
IP addresses/hostnames. If an IP address or host name is entered and the n parameter has a
value greater than 0, when a ping failure is detected on the primary IP address, pings are sent
to this second IP address/hostname. This ensures that if the main IP address becomes
unavailable for any reason and stops responding to ICMP requests, the router will check
another IP address before starting fail over procedures.
