Switch Management Commands 2048
Command Mode
Interface (VLAN) Configuration mode
User Guidelines
This command only applies to VLAN routing interfaces. When DHCPv6 is
enabled on a VLAN routing interface, the system automatically deletes all
manually configured IPv6 addresses on the interface.
Use the no ipv6 address dhcp command to release a leased address and to
disable DHCPv6 on an interface. The command no ipv6 address does not
disable the DHCPv6 client on the interface.
This command will fail if DHCPv6 server has been configured on the
interface.
Examples
In the following example, DHCPv6 is enabled on interface vlan2.
console#config
console(config)#interface vlan 2
console(config-if-vlan2)#ipv6 address dhcp
ipv6 enable (Interface Configuration)
Use the ipv6 enable command in Interface Configuration mode to enable
IPv6 on an interface. Use the no form of this command to reset the IPv6
configuration to the defaults.
