(a) Checking the log and interface

Communication may be interrupted by NIM or interface failure (or damage) or failure in the neighboring system. Check the log displayed by this system and the up/down status of interfaces using the show inpv6 interface command. For the procedure, see "3.9.1 Communication Is Disabled or Is Disconnected."

(b) Checking the status of the IPv6 DHCP server in this system

1.Checking if the IPv6DHCP server service is running

Confirm that information can be retrieved from the IPv6DHCP server daemon using the show ipv6 dhcp server

statistics command. If the show ipv6 dhcp server statistics command produces the following output, reset

IPv6DHCP server using configuration command service ipv6 dhcp. [Execution results]

>show ipv6 dhcp server statistics

>< show statistics >: dhcp6_server doesn't seem to be running.

2.Checking the remaining distributable prefixes
