Step 8 exit Example: Device(config-dhcpv6-vs)# exit Returns to DHCP pool configuration mode. Step 9 exit Example: Device(config-dhcpv6)# exit Returns to global configuration mode. Step 10 interface interface-id Example: Device(config)# interface gigabitethernet 1/0/1 Enters interface configuration mode, and specifies the interface to configure. Step 11 ipv6 dhcp server [poolname | automatic] [rapid-commit] [preference value] [allow-hint] Example: Device(config-if)# ipv6 dhcp server automatic Enables DHCPv6 server function on an interface. • poolname—(Optional) User-defined name for the IPv6 DHCP pool.
