a logical interface that is considered to be always up.
To display the Loopback Interface page, click System > Management > Loopback Interface.
A screen similar to the following displays.
To configure a loopback interface:
1. In the Loopback Interface Type field select whether the interface is an IPv4 or IPv6
loopback interface. The configuration fields vary based on the interface type.
2. For an IPv4 loopback interface, configure the following:
a. In the Loopback ID field select the loopback ID number
b. In the Primary Address field, input the primary IPv4 address for this interface in
dotted decimal notation.
c. In the Primary Mask field, input the primary IPv4 subnet mask for this interface in
dotted decimal notation.
d. View the logical status of the interface in the Loopback Interface Status field. A
loopback interface is always up.
3. For an IPv6 loopback interface, configure the following:
a. In the Loopback ID field select the loopback ID number.
b. Use the IPv6 Mode field to enable IPv6 on this interface using the IPv6 address.
This option is only configurable prior to specifying an explicit IPv6 address.
c. Use the IPv6 Address field to enter the IPv6 address in the format prefix/length.
d. Use the EUI64 field to optionally specify the 64-bit extended unique identifier
(EUI-64).
4. Click ADD to add the configured IPv4 or IPv6 loopback interface.
5. To remove the loopback interface configuration, select the box associated with the interface
to remove, and click DELETE.
6. To modify information about a configured interface, select the box associated with the
interface to modify, update the configuration information in the appropriate fields, and click
