Configuring 802.3ad Link Aggregation

See E120 and E320 Module Guide, Table 1, Modules and IOAs for detailed module
specifications.
See E120 and E320 Module Guide, Appendix A, IOA Protocol Support for information
about the modules that support 802.3ad link aggregation.
The configuration task examples in this chapter use the format for ERX7xx models,
ERX14xx models, and the ERX310 router to specify 802.3ad link aggregation.
For example, the following command specifies a Gigabit Ethernet interface on port 0 of
an I/O module in slot 4.
host1(config)#interface gigabitEthernet 4/0
When you configure a Gigabit Ethernet interface or a 10-Gigabit Ethernet interface on
E120 or E320 routers, you must include the adapter identifier as part of the interface
specifier. For example, the following command specifies a Gigabit Ethernet interface on
port 0 of the IOA installed in the upper adapter bay of slot 3.
host1(config)#interface gigabitEthernet 3/0/0
For more information about interface types and specifiers on E Series models, see Interface
Types and Specifiers in JunosE Command Reference Guide.
For more information about 802.3ad link aggregation implementations, consult the
following resources:
IEEE 802.1w (Rapid Reconfiguration of Spanning Tree)
IEEE 802.3ad (Link Aggregation)
To configure link aggregation on Ethernet interfaces, you must configure the Ethernet
interface, create the LAG bundle, and add the Ethernet interface as a member link in the
LAG bundle. Optionally, you can then configure IP, a VLAN subinterface, a PPPoE
subinterface, or MPLS for the LAG bundle.
For more information about specifying LAG interfaces and subinterfaces on E Series
routers, see Interface Types and Specifiers in JunosE Command Reference Guide.
