802.3ad Link Aggregation Platform Considerations

Module Requirements

Copyright © 2010, Juniper Networks, Inc.
NOTE: On the ES2 10G LM and ES2-S1 GE-8 IOA combination, you can only
configure IP or VLAN over a LAG bundle.
You can configure load balancing across 802.3ad links to provide quality of service (QoS).
To ensure that QoS is symmetrically applied to all the links, the router periodically
rebalances the traffic on the LAG. When you attach a QoS profile to the LAG, the load
balancing properties that are configured are applied to the LAG, and determines how
traffic is distributed.
For example, if VLANs are configured, IP queues are provisioned over the VLANs. In this
case, the default behavior is per-VLAN load balancing.
For more information, see Providing QoS for Ethernet Overview.
CE-side load balancing in a Martini layer 2 transport environment enables an E Series
router to interoperate with an 802.3ad switch in a topology designed for Ethernet link
aggregation. See chapter Configuring Layer 2 Services over MPLS in JunosE BGP and MPLS
Configuration Guide for more information.
You can configure 802.3ad link aggregation on the following E Series Broadband Services
Routers:
E120 router
E320 router
ERX1440 router
ERX1410 router
ERX710 router
ERX705 router
ERX310 router
For information about the modules that support 802.3ad link aggregation on ERX14xx
models, ERX7xx models, and the ERX310 router:
See ERX Module Guide, Table 1, Module Combinations for detailed module specifications.
See ERX Module Guide, Appendix A, Module Protocol Support for information about the
modules that support 802.3ad link aggregation.
