Kat,
You should really consider shaping as opposed to policing. You can do CAR without the PFC, just like you would a router, however this is slower and much more processor intensive. You can police with hardware but need a PFC. Shaping will provider a much more elegant approach to limiting the amount of bandwidth for whatever you need to limit (VLAN, protocol, etc). If you police traffic you end up forcing TCP/IP to re-transmit, however if you shape, traffic is queued and you will not get the re-transmits. Your traffic curve smoothes out and reduce your re-transmits. Shaping requires a PFC.
Thanks,
Patrick Greene

Does anyone know for sure that a 6509 with an MSFC2 module can do QOS,
rate-limiting? Do you need a PFC?
Any urls would also be greatly appreciated.
