Understanding Interface Naming Conventions on EX Series Switches
Juniper Networks EX Series Ethernet Switches use a naming convention for defining the
interfaces that is similar to that of other platforms running under Juniper Networks Junos
operating system (Junos OS). This topic provides brief information about the naming
conventions used for interfaces on EX Series switches. For additional information, see
the Junos OS Network Interfaces Configuration Guide.

Physical Part of an Interface Name
Network interfaces in Junos OS are specified as follows:
type-fpc / pic / port
EX Series switches apply this convention as follows:
•
type—EX Series interfaces use the following media types:
•
ge—Gigabit Ethernet interface
•
xe—10 Gigabit Ethernet interface
