Deployment Guide

Version Description
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
dot1p priority trac on the switch is scheduled to the current queue mapping. dot1p priorities within the same
queue must have the same trac properties and scheduling method.
ETS-assigned scheduling applies only to data queues, not to control queues.
The conguration of bandwidth allocation and strict-queue scheduling is not supported at the same time for a
priority group. If you congure both, the congured bandwidth allocation is ignored for priority-group trac when
you apply the output policy on an interface.
Related Commands
• bandwidth-percentage — bandwidth percentage allocated to priority trac in port queues.
