Switch Management Commands 1997
IPv6 auto configuration mode can be enabled in the Out-of-Band interface
only when IPv6 auto configuration or DHCPv6 is not enabled on any of the
in-band management interfaces.
The optional eui64 parameter indicates that the IPv6 address is configured to
use the EUI-64 interface ID in the low order 64 bits of the address. In this
parameter is specified, the prefix-length must be 64. This command is only
valid for switches equipped with an out-of-band interface.
ipv6 address dhcp
Use the ipv6 address dhcp command in Interface (VLAN) Configuration
mode to enable the DHCPv6 client on an IPv6 interface.
Syntax
ipv6 address dhcp
no ipv6 address dhcp
Default Configuration
DHCPv6 is disabled by default on routing interfaces.
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.
