Juniper JUNOSE 11.1.X - LINK LAYER CONFIGURATION 4-7-2010, Configuration Manual

Page: 234 / 774

For information about the modules that support 802.3ad link aggregation on the
E120 and E320 routers:
■
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.
Interface Specifiers
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

Interface Types and Specifiers in

Configuring 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 .
