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.
Interface Description Example
Physical The physical ports include Gigabit ports and are
numbe
red sequentially starting from one.
g1, g2, g3
Link Aggregation Group (LAG) LAG interfaces are logical interfaces that are only
used for bridg
ing functions.
l1, l2, l3
CPU Management Interface This is the internal switch interface responsible for the
switch base MAC address. This interface is not
configurable and is always listed in the MAC Address
Table.
