TCP

Device>Configure>TCP

The TCP dialog box displays the algorithm and retransmission timeout information for the device. The algorithm determines how long the system should wait after it has transmitted an unacknowledged segment before it should time out and retransmit the segment. This information helps control traffic congestion on your network.

The TCP window displays the following information:

Retransmission Algorithm (tcpRtoAlgorithm)

Algorithm used to compute the retransmission timeout. Possible values are rsre, vanj, constant, or other. rsre refers to MIL-STD-1778, app.B. vanj means Van Jacobson’s algorithm, and constant means a fixed value.

Min Retransmission Timeout (tcpRtoMin)

Lower boundary in milliseconds on the retransmission timeout. Its meaning depends on the algorithm used.

Max Retransmission Timeout (tcpRtoMax)

Maximum upper boundary in milliseconds allowed for a retransmission timeout. Its meaning depends on the algorithm.

Max Connections (tcpMaxConn)

Limit on the maximum number of concurrent TCP connections or specifies that the limit is dynamically determined.
