Configuring IPv6 Addresses on an Interface

To configure IPv6 addresses on an interface, perform the following steps:
If you have not configured any IPv6 addresses with the CLI, to enable IPv6 addressing, check the Enable
Step 1
IPv6 check box.
To make sure that the source addresses of IPv6 packets received on that interface are verified according
Step 2
to the source MAC addresses to ensure that the interface identifiers use the modified EUI-64 format,
check the Enforce EUI-64 check box. If the interface identifiers do not conform to the modified EUI-64
format, an error message appears.
Step 3 If you are not going to assign any other IPv6 addresses, to set the link-local address manually, enter an
address in the Link-local address field. A link-local address should start with FE8, FE9, FEA, or FEB,
for example fe80::20d:88ff:feee:6a82. Alternatively, click the ellipsis to choose a link-local address
from the Browse Link-local address dialog box.
After you have selected the link-local address, click OK to return to the IPv6 tab.
Step 4
The selected link-local address appears in the Link-local address field.
To enable address autoconfiguration, check the Enable address autoconfiguration check box. During
Step 5
the stateless autoconfiguration process, duplicate address detection (DAD) verifies the uniqueness of
new unicast IPv6 addresses before the addresses are assigned to interfaces (the new addresses remain in
a tentative state while duplicate address detection is performed). Duplicate address detection is
performed first on the new link-local address. When the link local address is verified as unique, then
duplicate address detection is performed all the other IPv6 unicast addresses on the interface. For more
information about DAD, see the
In the Interface IPv6 Addresses area, click Add.
Step 6
The Add IPv6 Address for Interface dialog box appears.
(Optional) Check the EUI-64 check box.
Step 7
Step 8 Click OK to save your settings.
The Interface IPv6 Addresses Address field appears with the modified EUI-64 address.

Configuring IPv6 Prefixes on an Interface

To configure IPv6 prefixes on an interface, perform the following steps:
In the Interface IPv6 Prefixes area, click Add.
