Frame Relay Traffic Shaping Summary

GTS

- Interface/subinterface level (no pvc level)
- Internal shaper is WFQ
- Could be used with WFQ/PQ/CQ at interface level

Legacy FRTS

- Enabled with frame-relay traffic-shaping
- PVC granularity
- Default to 56k/125ms once activated
- Could be used with WFQ/PQ/CQ per PVC
- Could not be used with WFQ/PQ/CQ at interface level (if FRF.12 2 dual fifo is enabled at interface level)
- Could use FRF12 of the map-class, per VC fragmentation

MQC based FRTS

- Needed for Voice-Adaptive Traffic Shaping
- Could use FRF 12 at interface level (for all vc of the interface)
- Incompatible with the command frame-relay traffic-shaping

MQC based Class based traffic shaping

- Use map-class
- Incompatible with frame-relay traffic-shaping
- Incompatible with adaptive shaping
- Use service policy with shaping configured on default-class or by pvc matching a dlci
- CBFWQ could be used to child policy
- FRF.12 is applied at interface level
