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.
Syntax: show ipv6 tcp connections
This display shows the following information.
TABLE 180 IPv6 local router information fields
This field... Displays...
Router < ipv6 address > on < interface >
< port >
The IPv6 address for a particular router interface.
Last update The amount of elapsed time (in minutes) between the current and
previous updates received from a router.
Hops The default value that should be included in the Hop Count field of the
IPv6 header for outgoing IPv6 packets. The hops 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.
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.
