Configuring the Scheduler Hierarchy for Hashed Load Balancing in 802.3ad Link
Aggregation Groups
The type of load balancing that the system performs depends on the configuration
of the scheduler hierarchy in the QoS profile.
To configure the scheduler hierarchy for hashed load balancing:

Enabling Default Subscriber Load Balancing for 802.3ad Link Aggregation Groups

The factory default contents of the lag-default QoS profile include an Ethernet queue
and the best-effort traffic class.
When you use the lag-default QoS profile, the system automatically sends traffic to
the Ethernet queue and uses hash load balancing for the Ethernet queues.
To enable subscriber load balancing as the default behavior for all LAGs, issue the
following command:
