General IPv6 TCP connection fields (Continued)TABLE 40
Field Description
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.
FREE TCP = percentage The percentage of free TCP control block (TCP) space.
FREE TCP QUEUE
BUFFER = percentage
The percentage of free TCP queue buffer space.
FREE TCP SEND BUFFER
= percentage
The percentage of free TCP send buffer space.
FREE TCP RECEIVE
BUFFER = percentage
The percentage of free TCP receive buffer space.
FREE TCP OUT OF
SEQUENCE BUFFER =
percentage
The percentage of free TCP out of sequence buffer space.
To display detailed information about a specified TCP connection, enter a command such as the
following at any CLI level.
device#show ipv6 tcp status 2000:4::110 179 2000:4::106 8222
TCP: TCP = 0x217fc300
TCP: 2000:4::110:179 <-> 2000:4::106:8222: state: ESTABLISHED Port: 1
Send: initial sequence number = 242365900
Send: first unacknowledged sequence number = 242434080
Send: current send pointer = 242434080
Send: next sequence number to send = 242434080
Send: remote received window = 16384
Send: total unacknowledged sequence number = 0
Send: total used buffers 0
Receive: initial incoming sequence number = 740437769
