Figure 44: Scheduler Class and Weighed Group Scheduling Priority Mapping
Example
The port based scheduler supports a port based shaper used for creating a sub-rate condition
on the egress port. Each individual strict scheduling level may also be configured with a
shaping rate used to limit the amount of bandwidth allowed for that strict level. In all, shaping
PIRs can be defined at the following points in the queuing and scheduling architecture:
• Per port shaper
• Per strict level shaper
