NOTE The device does not support stateful address auto configuration from a DHCPv6
server.
• Number of DAD Attempts—Enter the number of consecutive neighbor solicitation
messages that are sent while Duplicate Address Detection (DAD) is performed on the
interface’s Unicast IPv6 addresses. DAD verifies the uniqueness of a new Unicast IPv6
address before it is assigned. New addresses remain in a tentative state during DAD
verification. Entering 0 in this field disables duplicate address detection processing on
the specified interface. Entering 1 in this field indicates a single transmission without
follow-up transmissions.
• Send ICMPv6 Messages—Enable generating unreachable destination messages.
• MLD Version—IPv6 MLD version.
• IPv6 Redirects—Select to enable sending ICMP IPv6 redirect messages. These
messages inform other devices not to send traffic to the device, but rather to another
device.
STEP 8 Click Apply to enable IPv6 processing on the selected interface. Regular IPv6 interfaces have
the following addresses automatically configured:
• Link local address using EUI-64 format interface ID based on a device’s MAC address
• All node link local Multicast addresses (FF02::1)
• Solicited-Node Multicast address (format FF02::1:FFXX:X)
STEP 9 Click IPv6 Address Table to manually assign IPv6 addresses to the interface, if required. This
page is described in the IPv6 Addresses section.
STEP 10 To add a tunnel, select an interface (which was defined as a tunnel in the IPv6 Interfaces page)
in the IPv6 Tunnel Table and click IPv6 Tunnel Table. See IPv6 Tunnel.
STEP 11 Press the Restart button to initiate refresh of the stateless information received from the
DHCPv6 server.
DHCPv6 Client Details
The Details button displays information received on the interface from a DHCPv6 server.
It is active when the interface selected is defined as a DHCPv6 stateless client.
When the button is pressed, it displays the following fields (for the information that was
received from the DHCP server):
• DHCP Operational Mode—This displays Enabled if the following conditions are
fulfilled:
