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.
The IP address of the Layer 3 Switch.
The TCP port the Layer 3 Switch is using for the BGP4 TCP session
with the neighbor.
The IP address of the neighbor.
The TCP port the neighbor is using for the BGP4 TCP session with
the Layer 3 Switch.
The initial send sequence number for the session.
The next sequence number to be sent.
The number of sequence numbers sent by the Layer 3 Switch that
have not been acknowledged by the neighbor.
The number of sequence numbers sent to the neighbor.
The number of sequence numbers that the Layer 3 Switch
retransmitted because they were not acknowledged.
