Hierarchy Level


Configure dynamic load balancing (DLB) on LAG with specific mode type—assigned flow, per-packet, or flowlet) and ether type—ipv4, ipv6, or mpls.


Since ether-type is a global configuration and applicable to all LAGs in the system with DLB enabled, the CLI for specifying ether-type for LAG is added in the global format under forwarding-options. See ether-type for details.


QFX switches in a virtual chassis configuration do not support dynamic load balancing.



Fixed link assignment.
