Displaying BGP4 information
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 Layer 3 switch.
Local port The TCP port the Layer 3 switch 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 Layer 3
switch.
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 Layer 3 switch 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 Layer 3 switch 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.
TotalRcv The number of sequence numbers received from the neighbor.
DupliRcv The number of duplicate sequence numbers received from the neighbor.
