TCP Connection state The state of the connection with the neighbor. The connection can have
one of the following states:
• 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.
Byte Sent The number of bytes sent.
Byte Received The number of bytes received.
Local host The IP address of the device.
Local port The TCP port the device is using for the BGP4 TCP session with the
neighbor.
Remote host The IP address of the neighbor.
Remote port The TCP port the neighbor is using for the BGP4 TCP session with the
device.
ISentSeq The initial send sequence number for the session.
SendNext The next sequence number to be sent.
TotUnAck The number of sequence numbers sent by the device that have not been
acknowledged by the neighbor.
TotSent The number of sequence numbers sent to the neighbor.
ReTrans The number of sequence numbers that the device retransmitted
because they were not acknowledged.
UnAckSeq The current acknowledged sequence number.
IRcvSeq The initial receive sequence number for the session.
RcvNext The next sequence number expected from the neighbor.
SendWnd The size of the send window.
