Interaction Between Profile Preferred And Profile Capped Mode - Alcatel-Lucent 7950 Quality Of Service Manual

the min (child PIR, root PIR) and the FIR and CIR are fixed and equal. The child parenting
weights are thus not used. This impacts the show commands, for example offered rate information
will not be available. The output of some show commands (show qos policer-hierarchy ... detail)
should be adjusted for profile-preferred configurations.
If an intermediate arbiter is present, then polling is offered at different rates since the child policer
PIRs will be set based on this information so as to share the intermediate arbiter PIR in
proportional to their parenting weight to the intermediate arbiter.
