This table provides the subinterface related information
associated to the Ethernet-like interfaces.
The subinterface is a division of one physical interface into
multiple logical interfaces. As an example of what a typical
subinterface setup might look like on a device, a single
Ethernet port such as GigabitEthernet0/0 would be subdivided
into Gi0/0.1, Gi0/0.2, Gi0/0.3 and so on, each one performing as
if it were a separate interface.
