18.6.5.1 Overview of WFQ (CLI)
The scheduler serves the queues based on their priority, but when two or
more queues have data to transmit and their priority is the same, the
scheduler uses Weighted Fair Queuing (WFQ) to determine the priorities
within each priority. WFQ defines the transmission ratio, in bytes, between the
queues. All the service bundles under the interface inherit the WFQ profile
attached to the interface.
The system supports up to six WFQ interface profiles. Profile ID 1 is a pre-
defined read-only profile, and is used as the default profile. Profiles 2 to 6 are
user-defined profiles.
The following table provides an example of a WFQ profile.

You can attach one of the configured interface WFQ profiles to each interface.
By default, the interface is assigned Profile ID 1, the pre-defined system
profile.
