Syntax: show ipv6 tcp connections

This display shows the following information.

TABLE 35

General IPv6 TCP connection fields

 

 

 

Field

 

Description

 

 

Local IP address:port

The IPv4 or IPv6 address and port number of the local router interface

 

 

over which the TCP connection occurs.

 

 

Remote IP address:port

The IPv4 or IPv6 address and port number of the remote router interface

 

 

over which the TCP connection occurs.

 

 

 

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.
