Cisco Ethernet-like Sub Interface Table

1.3.6.1.4.1.9.9.645.1.2.1

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.
