Loopback Interface Commands 1063

Loopback Interface Commands
PowerConnect provides for the creation, deletion, and management of
loopback interfaces. They are dynamic interfaces that are created and deleted
by user configuration.
A loopback interface is always expected to be up. As such, it provides a means
to configure a stable IP address on the device which may be referred to by
other switches in the network. This interface never transmits data but may
receive data. It is typically expected to be used by routing protocols.
Support for the internal loopback address, if present, is limited to testing the
IP stack.
