The loopback interface is a virtual interface which can be assigned an IP address and used by routing
protocols. The loopback interface does not need to be connected to any devices and will always be
available if the Switch is functioning normally and connected to a network. You can enable multiple
loopback interfaces on the Switch, and each loopback interface must be uniquely identified.
The Switch can use a loopback interface address as the source address of all packets that originate
from the Switch. Filters can then be applied to the loopback address to protect the system.
