Send LCP echo request packet to the remote peer
When enabled, displays the configuration parameters that cause the router to send Link
Control Protocol (LCP) packets to the remote peer at specified intervals. This feature can be
useful for keeping a link active (W-WAN, for example).
Send LCP echo requests every s seconds
The value in this text box sets the interval at which to send the packets. When set to 0 ,
transmission of LCP packets is disabled.
Disconnect the link after n failed echo requests
The number of consecutive failed echo requests allowed before the router terminates the
link. When set to 0 , this functionality is disabled, such as the router will not terminate the link
if the LCP echo requests do not elicit a response from the remote.
Generate Heartbeats on this interface
When enabled, displays the configuration options controlling how the router sends heartbeat
packets. Generating a valid configuration enables the router to send heartbeat packets to the
specified destination. Heartbeat packets are UDP packets that contain various items of
information about the router and which may include status information that may be used to
locate its current dynamic IP address. Heartbeats may also contain GPS position information
and mobile telephone module information.
Send Heartbeat messages to IP address a.b.c.d every h hrs, m minutes, s secs
The left-hand text box contains the IP address of the destination for the heartbeat packets.
The remaining text boxes specify the desired interval between sending heartbeat packets.
Use interface x,y for the source IP address
Select of the source interface for the UDP heartbeats. Selecting an Ethernet source allows the
packets to follow the routing table instead of being sent out from the PPP interface on which
they are set.
Select transmit interface using the routing table
When enabled, causes the router to choose the best route from the routing table. If
unchecked, the exit interface will be the interface on which the heartbeat is configured.
Include IMSI information in the Heartbeat message
When enabled, causes the router to include the IMSI of the wireless MODEM module in the
heartbeat packet.
