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 to increase bandwidth, provide graceful degradation as failure occurs, and increase
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
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 number
Specify the link speed for the aggregated Ethernet bundle:
3.
[edit interfaces]
user@switch# set ae0 aggregated-ether-options
Specify the members to be included within the aggregated Ethernet bundle:
4.
[edit interfaces]
user@switch# set xe-fpc/pic/port ether-options
user@switch# set xe-fpc/pic/port 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 address
