23.3.2 Checking the Number of Assignable Prefixes

To check the number of prefixes that can be assigned to clients, execute the show ipv6 dhcp server statistics command to display a list and check the prefix pools section. Make sure that the displayed number is greater than the number of clients to which you want to distribute prefixes.
