[c-nsp] Policing Question

[Bill ford]

Guys,


Need your help on this...



Here is the  scenario:
  
 We have a Catalyst 6509 with Sup  720+Policy Feature Card 3 connected to the Internet gateway Switch (catalyst  3750G). We are running Layer 3 etherchannel between the Cat 6509 and Cat  3750G.
  
 We need to restrict the bandwidth  for one of the customer. 
  
 Requirement is as  follows:
  
 CIR of 4 Mbps and burst up to 8 Mb  based on availability.
  
 Thinking of using policing with ACLs  based on the public IP address range on the customer, however few questions  here.
  
 1) Is it advisable to do Policing  only on the Cat 6509s in both direction and avoid do any changes on the Cat  3750G. Is this the right way?
  
 2) What should be the CIR, bc and be  values to provide double the burst than CIR based on avaliability?
  
 Is the below statement correct? I  believe Tc value for Cat 6509s is 0.00025 seconds, calculation is based on  that.
  
 police cir 4194304 bc 2000 be 4000  conform-action transmit exceed-action drop violate-action  drop
  
 3) Is there any issues applying  Policing on L3 etherchannels in both ways on Cat  6509s?
  
 Any help will be  appreciated.
 Thanks in advance,

Bill
