Ping responses are expected within n seconds
When set to a non-zero value, the router waits for the interval specified for a response from a
PING request before applying the Send pings every h hrs m mins s secs if ping responses
are not being received. If this parameter is set to 0 (default), the time specified in the in Send
n byte pings to IP host a.b.c.d every h hrs m mins s secs is allowed before applying the
Send pings every h hrs m mins s secs if ping responses are not being received.
Only send Pings when this interface is “In Service”
When enabled, the interface sends ICMP echo requests only when it is in service. The default
setting is off, and ICMP echo requests are sent when the interface is in service and out of
service.
New connections to resume with previous Ping interval
When enabled, this parameter controls the ping interval after deactivating and subsequently
reactivating the mobile interface. It sets the ping interval to the same interval in use when the
mobile link last disconnected.
Reset the link if no response is received within s seconds
An amount of time after which the device does not receive any ping response, the router
terminates the mobile connection in an attempt to re-establish communications. Because by
default the mobile link is always on, the router automatically attempts to re-establish a PPP
connection that has been terminated.
Use the ETH 0 IP address as the source IP address
When enabled, the router uses the IP address of ETH0 instead of the current IP address of the
mobile interface as the source address for the auto ping packets.
Note This parameter is useful to send the monitoring pings down a VPN tunnel where the
source IP address needs to match the LAN. Defer sending pings if IP traffic is being received
When enabled, the timer configured in the Send n byte pings to IP host a.b.c.d every h hrs
m mins s secs parameter is reset if IP data is sent across the mobile link.
