To display detailed information about a specified TCP connection, enter a command such as the
following at any CLI level.
TCP state The state of the TCP connection. Possible states include the following:
• LISTEN – Waiting for a connection request.
• SYN-SENT – Waiting for a matching connection request after having
sent a connection request.
• SYN-RECEIVED – Waiting for a confirming connection request
acknowledgment after having both received and sent a connection
request.
• ESTABLISHED – Data can be sent and received over the
connection. This is the normal operational state of the connection.
• FIN-WAIT-1 – Waiting for a connection termination request from the
remote TCP, or an acknowledgment of the connection termination
request previously sent.
• FIN-WAIT-2 – Waiting for a connection termination request from the
remote TCP.
• CLOSE-WAIT – Waiting for a connection termination request from
the local user.
• CLOSING – Waiting for a connection termination request
acknowledgment from the remote TCP.
• LAST-ACK – Waiting for an acknowledgment of the connection
termination request previously sent to the remote TCP (which
includes an acknowledgment of its connection termination
request).
• TIME-WAIT – Waiting for enough time to pass to be sure the remote
TCP received the acknowledgment of its connection termination
request.
• CLOSED – There is no connection state.
