Displaying global IPv6 information

From the IPv6 host, you can display information about IPv6 devices to which the host is connected.

The host learns about the devices through their router advertisement messages. To display

information about the IPv6 devices connected to an IPv6 host, enter the following command at any

CLI level.

Syntax: show ipv6 router

If you configure your device to function as an IPv6 device (configure IPv6 addresses on the

interfaces and enable IPv6 routing using the ipv6 unicast-routing command) and then enter the

show ipv6 router command, you will receive the following output.

Meaningful output for this command is generated for devices configured to function as IPv6 hosts

only.

This display shows the following information.

Displaying IPv6 TCP information

You can display the following IPv6 TCP information:

• General information about each TCP connection on the device, including the percentage of

free memory for each of the internal TCP buffers.

• Detailed information about a specified TCP connection.

TABLE 87 IPv6 local router information fields

This field... Displays...

Router ipv6 address on interface port The IPv6 address for a particular interface.

Last update The amount of elapsed time (in minutes) between the current and

previous updates received from a device.

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

device for which you are displaying information and should be followed

by IPv6 hosts attached to the device. A value of 0 indicates that the

device leaves this field unspecified.

Lifetime The amount of time (in seconds) that the device is useful as the default

device.

Reachable time The amount of time (in milliseconds) that a device assumes a neighbor

is reachable after receiving a reachability confirmation. The reachable

time value applies to the device for which you are displaying information

and should be followed by IPv6 hosts attached to the device. A value of 0

indicates that the device 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

device for which you are displaying information and should be followed

by IPv6 hosts attached to the device. A value of 0 indicates that the

device leaves this field unspecified.
