TCPKEEPALIVETIME (JANUS DEFINE parameter)
Set TCP Keepalive time interval
TCPKEEPALIVE is a parameter on JANUS DEFINE, which defines and sets characteristics of a Janus port.
This parameter specifies the time interval in seconds between TCP keepalive packets sent on active connections to test if they are, in fact, still connected.
TCPKEEPALIVETIME has no effect unless the TCPKEEPALIVE parameter is also set to enable TCP keepalives.
Since the TCP/IP stack does the keepalives, the overhead in Model 204 for setting this parameter is virtually zero.
If not set, or set to 0, and TCPKEEPALIVE the TCP stack's default keepalive intervale is used. This interval is usually 7200 (2 hours), a value so high that it renders TCP keepalives virtually useless.
This parameter is only available in Model 204 Version 8.0 and later.
TCPKEEPALIVETIME is valid for all port types.
