## Procedure steps

1. From the navigation tree, double-click IP Routing.

2. In the IP Routing tree, double-click TCP/UDP.

## Variable definitions

The following table describes the fields of the TCP Globals tab.

Field | Description
--- | ---
RtoAlgorithm | Specifies the algorithm to determine the timeout value used for retransmitting unacknowledged octets.
RtoMin | Specifies the minimum value permitted by a TCP implementation for the retransmission timeout, measured in milliseconds.
RtoMax | Specifies the maximum value permitted by a TCP implementation for the retransmission timeout, measured in milliseconds.
MaxConn | Specifies the limit on the total number of TCP connections that the entity can support. In entities where the maximum number of connections is dynamic, this object contains the value -1.
