Configuring Aggregated Ethernet Interfaces (CLI Procedure)

Junos OS Release 10.0 or earlier, reboot the switch.
You can see whether the operating mode has been changed to the new mode you
configured by issuing the

Use the link aggregation feature to aggregate one or more links to form a virtual link or
link aggregation group (LAG). The MAC client can treat this virtual link as if it were a single
link. Link aggregation increases bandwidth, provides graceful degradation as failure
occurs, and increases availability.
NOTE: An interface with an already configured IP address cannot form part
of the aggregation group.
To configure aggregated Ethernet interfaces, using the CLI:
Specify the number of aggregated Ethernet interfaces to be created:
1.
[edit chassis]
user@switch# set aggregated-devices ethernet device-count 2
Specify the minimum number of links for the aggregated Ethernet interface (aex),
2.
that is, the defined bundle, to be labeled "up":
NOTE: By default only one link must be up for the bundle to be labeled
"up".
[edit interfaces]
user@switch# set ae0 aggregated-ether-options minimum-links 2
Specify the link speed for the aggregated Ethernet bundle:
3.
[edit interfaces]
user@switch# set ae0 aggregated-ether-options link-speed 10g
Specify the members to be included within the aggregated Ethernet bundle:
4.
[edit interfaces]
user@switch# set xe-0/1/0 ether-options 802.3ad ae0
user@switch# set xe-1/1/0 ether-options 802.3ad ae0
Specify an interface family for the aggregated Ethernet bundle:
5.
[edit interfaces]
user@switch# set ae0 unit 0 family inet address 192.0.2.0/25
