Displaying IPv6 TCP information

You can display the following IPv6 TCP information:
• General information about each TCP connection on the router, including the percentage of free memory for each of the internal
TCP buffers.
• Detailed information about a specified TCP connection.
To display general information about each TCP connection on the router, enter the following command at any CLI level.
device#show ipv6 tcp connections

FREE TCP QUEUE BUFFER = 99 percent
FREE TCP SEND BUFFER = 97 percent
FREE TCP RECEIVE BUFFER = 100 percent
FREE TCP OUT OF SEQUENCE BUFFER = 100 percent

Description
The IPv4 or IPv6 address and port number of the local router interface
over which the TCP connection occurs.
The IPv4 or IPv6 address and port number of the remote router interface
over which the TCP connection occurs.
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).
