IPv6 local router information fields (Continued) TABLE 39
Field Description
Lifetime The amount of time (in seconds) that the router is useful as the default router.
Reachable time The amount of time (in milliseconds) that a router assumes a neighbor is reachable after
receiving a reachability confirmation. The reachable time value applies to the router for
which you are displaying information and should be followed by IPv6 hosts attached to the
router. A value of 0 indicates that the router leaves this field unspecified.
Retransmit time The amount of time (in milliseconds) between retransmissions of neighbor solicitation
messages. The retransmit time value applies to the router for which you are displaying
information and should be followed by IPv6 hosts attached to the router. A value of 0
indicates that the router leaves this field unspecified.
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
Local IP address:port <-> Remote IP address:port TCP state
10.168.182.110:23 <-> 10.168.8.186:4933 ESTABLISHED
10.168.182.110:8218 <-> 10.168.182.106:179 ESTABLISHED
10.168.182.110:8039 <-> 10.168.2.119:179 SYN-SENT
10.168.182.110:8159 <-> 10.168.2.102:179 SYN-SENT
2000:4::110:179 <-> 2000:4::106:8222 ESTABLISHED (1440)
Total 5 TCP connections
TCP MEMORY USAGE PERCENTAGE
FREE TCP = 98 percent
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
Syntax: show ipv6 tcp connections
This display shows the following information.
General IPv6 TCP connection fields TABLE 40
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.
