802.1Q VLANs Overview on page 26 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...
All EX Series switches have this software-only virtual interface that is always up. The loopback interface provides a stable and consistent interface and IP address on the switch. Management interface The Juniper Networks Junos operating system (Junos OS) for EX Series switches automatically creates the switch's management Ethernet interface, . The management Ethernet interface provides an out-of-band method for connecting to the switch.
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.

PIC Concentrator. EX Series interfaces use the following convention for the FPC number in interface names: On an EX2200 switch, an EX3200 switch, a standalone EX3300 switch, a standalone EX4200 switch, a standalone EX4300 switch, a standalone EX4500, and a standalone EX4550 switch, FPC refers to the switch itself.
(ports) with the link. All the interfaces must have the same speed and be in full-duplex mode. Juniper Networks Junos operating system (Junos OS) for EX Series Ethernet Switches assigns a unique ID and port priority to each interface.
Understanding the Algorithm Used to Hash LAG Bundle and Egress Next-Hop ECMP Traffic Juniper Networks EX Series and QFX Series use a hashing algorithm to determine how to forward traffic over a link aggregation group (LAG) bundle or to the next-hop device when equal-cost multipath (ECMP) is enabled.
Layer 3 subinterfaces to route traffic among multiple VLANs along a single trunk line that connects a Juniper Networks EX Series Ethernet Switch to a Layer 2 switch. Only one physical connection is required between the switches. This topology is often called a router on a stick or a one-armed router when the Layer 3 device is a router.
This is known as strict mode unicast RPF. NOTE: On Juniper Networks EX3200, EX4200, and EX4300 Ethernet Switches, the switch applies unicast RPF globally to all interfaces when unicast RPF is configured on any interface. For additional information, see “Limitations of the Unicast RPF Implementation on EX3200, EX4200, and...

[edit interfaces] hierarchy level. NOTE: Juniper Networks routers and switches support destination prefixes when used in point-to-point Ethernet configurations; however, they are not supported by many other devices, such as hosts, hubs, routers, or switches. You must determine if the peer system also supports destination prefixes before configuration.
Configuring Accounting for the Physical Interface Juniper Networks routers and switches can collect various kinds of data about traffic passing through the router and switch. You can set up one or more accounting profiles that specify some common characteristics of this data, including the following:...

Configuring the Fields in the Algorithm Used To Hash LAG Bundle and ECMP Traffic (CLI Procedure) Juniper Networks EX Series and QFX Series switches use a hashing algorithm to determine how to forward traffic over a Link Aggregation group (LAG) bundle or to the next-hop device when equal-cost multipath (ECMP) is enabled.
Options number —Maximum number of aggregated Ethernet logical interfaces on the switch. Range: 1 through 32 for EX2200, EX3200, and standalone EX3300 switches and for EX3300 Virtual Chassis Range: 1 through 64 for standalone EX4200, standalone EX4500, and EX6200 switches...
The TDR test is supported on the following switches and interfaces: EX2200, EX3200, EX3300, and EX4200 switches—RJ-45 network interfaces. The TDR test is not supported on management interfaces and SFP interfaces.
It can also detect polarity swaps, pair swaps, and excessive skew. The TDR test is supported on the following switches and interfaces: EX2200, EX3200, EX3300, and EX4200 switches—RJ-45 network interfaces. The TDR test is not supported on management interfaces and SFP interfaces.
