Link Aggregation Group (LAG)

Copyright © 2015, Juniper Networks, Inc.
This topic describes:
Link Aggregation Group (LAG) on page 9
Link Aggregation Control Protocol (LACP) on page 10
You configure a LAG by specifying the link number as a physical device and then
associating a set of interfaces (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.
The ID and priority are not configurable.
The number of interfaces that can be grouped into a LAG and the total number of LAGs
supported on a switch varies according to switch model.
Series switches and the maximum number of interfaces per LAG and the maximum
number of LAGs they support. MX Series devices can support up to 64 LAGs.

When configuring LAGs, consider the following guidelines:
You must configure the LAG on both sides of the link.
You must set the interfaces on either side of the link to the same speed.
You can configure and apply firewall filters on a LAG.
