1.7 Configuring Queue Scheduling Algorithm

1.7.1 Prerequisites

Mapping relationships between the priority and local precedence queue have
been established. Refer to 1.5 Configuring Priority - Local Precedence Queue
Mapping.
The priority to trust has been determined (from the 802.1p priority, IP precedence,
and DSCP precedence). Refer to 1.6 Configuring Packet Priority.
The scheduling algorithm (WRR or HQ+WRR) has been determined, and the
weight value for each queue has been allocated.
