EX Series Switches Interfaces Overview
Juniper Networks EX Series Ethernet Switches have two types of interfaces: network
interfaces and special interfaces. This topic provides brief information about these
interfaces. For additional information, see the Junos OS Interfaces Fundamentals
Configuration Guide.
For information about interface-naming conventions on EX Series switches, see
“Understanding Interface Naming Conventions on EX Series Switches” on page 6.
This topic describes:

Network Interfaces on page 3
•
Special Interfaces on page 4
Network Interfaces
Network interfaces connect to the network and carry network traffic. Table 3 on page 4
lists the types of network interfaces supported on EX Series switches.
