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.
