SET CONFIGURATION PROTOCOL
TCP Qualifiers
/MTU_SEGMENT_SIZE
/NOMTU_SEGMENT_SIZE
Optional. Default: /NOMTU_SEGMENT_SIZE.
If a connection is more than one hop away, sets the segment size. Specify one of
the following:
/MTU_SEGMENT_SIZE Sets the segment size as close as possible to the
maximum transfer unit (MTU) size.
/NOMTU_SEGMENT_SIZE Sets the segment size as close as possible to the
standard 512 bytes.
/DELAY_ACK
/NODELAY_ACK
Optional. Default: /DELAY_ACK.
Enables or disables a delay before sending acknowledgments:
/DELAY_ACK ACKs are generated with a delay.
/NODELAY_ACK ACKs are generated without any delay.
/DROP_COUNT=n
Optional.
Number of idle probes that can go unsatisfied before the software declares a TCP
connection dead and closes it.
/PROBE_TIMER=n
Optional. Default: 75 seconds.
Number of seconds between probes for idle TCP connections (when the
SO_KEEPALIVE option is set). If the remote system fails to respond, the
connection is removed. Also, when initiating a TCP connection request, indicates
the maximum number of seconds that the software waits for a response from the
remote system before the request times out.
/QUOTA=[SEND=bytes,RECEIVE=bytes]
Optional.
Specifies the queue size (in bytes) for messages.
The options for setting TCP message queue size are:
• RECEIVE:n — Receive queue size. Default: 4096 bytes.
• SEND:n — Send queue size. Default: 4096 bytes.
/WINDOW_SCALE
/NOWINDOW_SCALE
Optional.
Turns TCP window scaling on and off. Default is on.
Scaling allows windows larger than 64 KB to be represented in the normal 16-bit
TCP window field. Large windows allow improved throughput. Turning this
option off may help troubleshoot communication problems with another TCP/IP
implementation.
