Defining an IPv6 Interface

The IPv6 Interfaces Page displays the switch's IPv6 interface parameters and
enables configuring this interface. An IPv6 interface can be configured on a port, a
LAG, VLAN, or ISATAP tunnel interface. The switch supports one IPv6 interface as
an IPv6 end device.
A tunnel interface is configured with an IPv6 address based on the settings
defined in the IPv6 Tunnel Page.
To configure IPv6 interfaces:
Click Administration > Management Interface > IPv6 Interfaces.
The IPv6 Interfaces Page opens.
This page displays the IPv6 interfaces already configured.
Click Add to add a new IPv6 interface, that is to define on which interface IPv6 is
enabled. The Add IPv6 Interface Page opens.
Enter the values.
• IPv6 Interface—Select a specific port, LAG, VLAN, or ISATAP tunnel.
• 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 new Unicast IPv6 addresses before the addresses are
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.
• IPv6 Address Auto Configuration— If enabled, the switch supports IPv6
stateless address auto configuration of site local and global IP address from
the IPv6 router advertisement received on the interface. The switch does not
support stateful address auto configuration.
• Send ICMPv6 Messages—Enable generating unreachable destination
messages.
