address for a selected VLAN interface on the page for modifying VLAN interfaces, you need to click the
correct Apply button to submit the modification.
• After you change the IP address of the VLAN interface you are using to log in to the device, you will be
disconnected from the device. You can use the changed IP address to re-log in.

Configuration guidelines

When you configure VLAN interfaces, follow these guidelines:
A link-local address is automatically generated for an IPv6 VLAN interface after an IPv6 site-local
•
address or global unicast address is configured for the VLAN interface. This generated link-local
address is the same as the one generated in the Auto mode. If a manually assigned link-local
address is available, the manually assigned one takes effect. After the manually assigned link-local
address is removed, the automatically generated one takes effect.
• For an IPv6 VLAN interface whose IPv6 link-local address is generated automatically after you
assign an IPv6 site-local address or global unicast address, removing the IPv6 site-local address or
global unicast address also removes the generated IPv6 link-local address.
Description
Auto Configure the way in which the VLAN interface obtains an IPv6 link-local address.
Select the Auto or Manual option:
•
Auto—Indicates that the device automatically assigns a link-local address for the
VLAN interface according to the link-local address prefix (FE80::/64) and the
Manual
link-layer address of the VLAN interface.
•
Manual—Configures an IPv6 link-local address for the VLAN interface manually.
Select Up or Down in the Admin Status list to bring up or shut down the selected VLAN
interface.
When the VLAN interface fails, you can shut down and then enable the VLAN
interface, which may restore it.
By default, a VLAN interface is down if all Ethernet ports in the VLAN are down;
Admin
otherwise, the VLAN interface is up.
Status
NOTE:
•
The current VLAN interface state in the Modify IPv4 Address and Modify IPv6
Address frames changes as the VLAN interface state is modified in the Admin
Status list.
•
The state of each port in the VLAN is independent of the VLAN interface state.
Assign an IPv6 site-local address or global unicast address to the VLAN interface.
Enter an IPv6 address in the field and select a prefix length in the list next to it.
Add IPv6
Unicast
The prefix of the IPv6 address you entered cannot be FE80::/10, the prefix of the
Address
link-local address.
The prefix of the IPv6 site-local address you enter must be FEC0::/10.
Specify to generate IPv6 site-local addresses or global unicast addresses in the EUI-64
format.
EUI-64
If the EUI-64 box is not specified, manually configured IPv6 site-local addresses or
global unicast addresses are used.
