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