GS748T Smart Switch
Interface Naming Convention
The GS748T Smart Switch supports physical and logical interfaces. Interfaces are identified
by their type and the interface number. All the physical ports 1–48 are Gigabit ports and the
SFP Ports 47–50 support 1000M Speed fiber modules. Ports 47–48 are Combo ports and
ports 49–50 will support dedicated SFP modules. The number of the port is identified on the
front panel. You can configure the logical interfaces by using the software. The following table
describes the naming convention for all interfaces available on the switch.
