/KEEPALIVE_TIMER[=secs]

    Allows you to control the maximum interval between idle run
    messages sent by your local node to another service node to which
    it has a LAT connection. The interval is in seconds. Your node
    sends these messages when no other traffic is being generated
    over the virtual circuit. If the service node acknowledges
    these messages, your node will continue to monitor the status
    of the circuit. If your node does not receive acknowledgment, it
    responds as if the circuit is down.

    Use this qualifier only if your node allows outgoing connections
    (/CONNECTIONS=OUTGOING_ONLY or /CONNECTIONS=BOTH).

    The default value is 20. VSI recommends this value for
    normal LAN environments. For a heavily loaded LAN, consider
    using a higher value. Set the timer in the range of 10 to 255.
    For applications that require quick notification and possible
    failover of a service node failure, use a lower value. You cannot
    change this value if active or pending connections exist.
