IPv6 Address for Interface Dialog Box
This dialog box is used to add or edit an IPv6 address assigned to an ASA or FWSM interface. Multiple
IPv6 addresses can be assigned to the interface in the IPv6 panel of the Add Interface or Edit Interface
dialog box.
Note This dialog box is available only on ASA 7.0+ devices in routed mode; ASA 8.2+ devices in transparent
mode; and FWSM 3.1+ devices in routed mode.
Navigation Path
You can access the IPv6 Address for Interface dialog box:
•From the IPv6 panel of the ASA or FWSM Add Interface and Edit Interface dialog boxes.
Interface IPv6 Addresses The IPv6 addresses assigned to the interface are specified in this
section of the dialog box.
•Link-Local Address – To override the link-local address that is
automatically generated for the interface, enter the desired IPv6
link-local address in this field.
The link-local address is composed of the link-local prefix
FE80::/64 and the interface ID in Modified EUI-64 format. For
example, an interface with a MAC address of 00E0.B601.3B7A
would have a link-local address of FE80::2E0:B6FF:FE01:3B7A.
An error will occur if another host is using the specified address.
•Enable Address Auto-Configuration – Select this option to
enable automatic configuration of IPv6 addresses on the interface
using stateless autoconfiguration. The addresses are configured
based on the prefixes received in Router Advertisement (RA)
messages. If a link-local address has not been configured, then one
is automatically generated for this interface. An error occurs if
another host is already using the generated link-local address.
•The table in this section displays the IPv6 addresses assigned to
this interface. Use the Add Row, Edit Row, and Delete Row buttons
below this table to manage these entries. (These are standard
buttons, as described in Using Tables, page1-45.)
Add Row and Edit Row open the IPv6 Address for Interface Dialog
Box, page 45-33.
Interface IPv6 Prefixes Use the table in this section to configure which IPv6 prefixes (that is,
the network portion of the IPv6 addresses) are included in IPv6 router
advertisements. Use the Add Row, Edit Row, and Delete Row buttons
below this table to manage these entries. (These are standard buttons,
as described in Using Tables, page1-45.)
Add Row and Edit Row open the IPv6 Prefix Editor Dialog Box,
page 45-34.
