Setting the Minimum Retransmission Timeout

You can specify a minimum value for the retransmission timeout. When one side

of a TCP connection sends a frame and does not receive an acknowledgment from

the other side of the connection within the timeout period, the sending station

retransmits the frame.

If you are transmitting on a high-speed network and you set the minimum

retransmission timeout value too high, network performance may degrade because

TCP must wait for the timeout period to elapse before retransmitting

unacknowledged data.

Using the BCC

By default, the router sets the minimum retransmission timeout value to 250

milliseconds (ms).

To specify a value for the minimum retransmission timeout, navigate to the TCP

prompt and enter:

min-rto

integer>

integer

is a value from 100 to 15,000 milliseconds (ms).

For example, the following command sets the value for the minimum

retransmission timeout to 300 ms:

tcp#

min-rto 300

tcp#
