IPv6 Addressing Configuration

Enabling DHCPv6

Enabling the DHCPv6 option on a VLAN allows the switch to obtain a global

unicast address and an NTP (network time protocol) server assignment for a

Timep server. (If a DHCPv6 server is not needed to provide a global unicast

address to a switch interface, the server can still be configured to provide the

NTP server assignment. This is sometimes referred to as “stateless DHCPv6”.)

Syntax: [no] ipv6 address dhcp full [rapid-commit]

This option configures DHCPv6 on a VLAN, which initiates

transmission of DHCPv6 requests for service. If IPv6 is not

already enabled on the VLAN by the ipv6 enable command, this

option also enables IPv6 and causes the switch to autocon-

figure a link-local unicast address with an EUI-64 interface

identifier.

Notes: A DHCPv6 server does not assign link-local

addresses, and enabling DHCPv6 on a VLAN does not

affect a pre-existing link-local address configured on the

VLAN.

A DHCPv6-assigned address can be configured on a VLAN

when the following is true:

• The assigned address is not on the same subnet as a

previously configured autoconfig address.

• The maximum IPv6 address limit on the VLAN or the

switch has not been reached.

If a DHCPv6 server responds with an IPv6 address assign-

ment, this address is assigned to the VLAN. (The DHCPv6-

assigned address will be dropped if it has the same subnet as

another address already assigned to the VLAN by an earlier

autoconfig command.)
