When you configure aggregated Ethernet interfaces, you configure a logical interface
that is called a bundle or a LAG. Each LAG can include up to 8 or 12 Ethernet interfaces,
depending on the switch model.
In the show interfaces and
in the interface-name option to specify groups of interface names without having to type
each name individually. You must enclose all wildcard characters except the asterisk (*)
in quotation marks (" ").

IEEE 802.3ad link aggregation enables you to group Ethernet interfaces to form a single
link layer interface, also known as a link aggregation group (LAG) or bundle.
Aggregating multiple links between physical interfaces creates a single logical
point-to-point trunk link or a LAG. The LAG balances traffic across the member links
within an aggregated Ethernet bundle and effectively increases the uplink bandwidth.
Another advantage of link aggregation is increased availability, because the LAG is
composed of multiple member links. If one member link fails, the LAG continues to carry
traffic over the remaining links.
Link Aggregation Control Protocol (LACP), a component of IEEE 802.3ad, provides
additional functionality for LAGs.
This topic describes:
Link Aggregation Group (LAG) on page 867
Link Aggregation Control Protocol (LACP) on page 868
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. The Junos OS for J-EX Series 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. Table 119 on page 868 lists the
J-EX Series switches and the maximum number of interfaces per LAG and maximum
number of LAGs they support.
