Juniper Networks EX Series Ethernet Switches have two types of interfaces: network
interfaces and special interfaces. This topic provides brief information on these interfaces.
For additional information, see the Junos OS Network Interfaces Configuration Guide at

For information on interface-naming conventions on EX Series Switches, see
"Understanding Interface Naming Conventions on EX Series Switches" on page 1097.
This topic describes:
Network Interfaces on page 1095
Special Interfaces on page 1096
Network interfaces connect to the network and carry network traffic. Table 160 on page 1095
lists the types of network interfaces supported on EX Series switches.
Purpose
All EX Series switches allow you to group Ethernet interfaces at the physical layer to form a
single link layer interface, also known as a link aggregation group (LAG) or bundle. These
aggregated Ethernet interfaces help to balance traffic and increase the uplink bandwidth.
