HQoS configuration for PBB
The following configurations define the hierarchy for the PBB HQoS in Figure 19 .
Refer to “HQoS scheduler policy” on page 183 for additional information on configuring the HQoS
scheduler policies.
At the level-0 scheduler policy configuration, the main difference is the absence of an explicit
"default traffic" path. A default path is created implicitly with strict priority scheduling among the 8
default traffic queues. The implicit default traffic path is always lower priority than customer traffic
regardless of level-0 scheduler type.
