# TCP Connections

Device>Configure>TCP Connections

Information on TCP connections is usually used for debugging and provides information on which TCP ports are in use on the switch.

The TCP Connections window displays the following information:

Local Address (tcpConnLocalAddress)

Local IP address for the TCP connection.

Port (tcpConnLocalPort)

Local port number for the TCP connection.

Remote Address (tcpConnRemAddress)

Remote IP address for the TCP connection.

Port (tcpConRemPort)

Remote port number for the TCP connection.

State (tcpConnState)

Current status of the TCP connection. Possible values are closed, listen, synSent, synReceived, established, finWait1, finWait2, closeWait, lastAck, closing, timeWait, or delete TCB (transmission control block).

Note: the only value which writable by a management station is deleteTCB(12); all others are read-only. Accordingly, it is appropriate for an agent to return a ‘badValue’ response if a management station attempts to set this object to any other value.
