Hi Danny,
Here are the main differences.
Generic Traffic Shaping:
- Works on any interface/subinterface type
- Shapes traffic on that interface/subinterface basis
- Can use any physical interface queuing (FIFO, PQ, CQ or WFQ)
- Only uses WFQ as the shaping queue (that is, on the input of the shaper)
In contrast, Frame Relay Traffic Shaping:
- Works only on Frame Relay interfaces/subinterfaces.
- Shapes traffic inside individual FR Virtual Circuits. (So there is no global pre-classification of traffic(as in GTS), but packets are sent to their individual VCs instead. Shaping is then performed on a per-VC basis, with a separate shaping queue/token bucket for each VC. Packets coming out of their individual per-VC shapers are then sent to the physical interface queue (Tx queue/Tx ring).
- Only permits WFQ as the physical interface queuing method
- Can use any queuing method as the shaping queue (that is, on the input of the shaper)
Generic Traffic Shaping would be considered equivalent to Frame Relay Traffic Shaping when itbs configured on point-to-point Frame Relay subinterfaces.
HTH.
Best Regards,
Nauman

Hi Guys,
Can someone please explain when to use GTS instead of FRTS or vice versa.
