Configuring idle timeout values to drop network connection.

• First Keepalive has to be enabled. You do this by typing the following from the PortServer root prompt:

  #> set tcp active=on

  Once this is done, tcp will see how long a connection has been idle (no traffic at all). This value is controlled by the "idle" setting. The default value for this is 2 hours.

• Configuring the idle setting:

  #> set tcp keepalive_idle=hr:min:sec

  Once a connection has been idle for the specified time, tcp will try to communicate with the other end, by sending it probes. The number of probes is controlled by the "probe_cnt" setting. If a response to a probe is not received, within the "interval" time, another probe is sent. Once number of probes has been sent without any response, the connection is timed out.

• With the PortServer default settings, with keepalive turned on, a connection is timed out approximately after 2 hours and 12 minutes.
