The book!6Cisco DQOS Exam Certification Guide!7:
The first big difference between FRTS and the other shapers has to do with queuing tool support.
FRTS does not allow any IOS queuing tool to be used on the physical interface when FRTS
is configured for VCs on the interface. Even if a queuing tool has already been configured, IOS
removes the configuration from the physical interface when FRTS is enabled. FRTS does supply
the largest list of options for queuing tools for the shaping queue: FIFO, PQ, CQ, CBWFQ,
LLQ, and WFQ are all available.
Router#show traffic-shape queue
Traffic queued in shaping queue on Serial1/0 dlci 405
Queueing strategy: weighted fair
Queueing Stats: 0/600/64/0 (size/max total/threshold/drops)
