The way you put the question makes policing the only choice. Either a
police statement as you specified, or older CAR will do. Shaping only kicks
in during congestion periods and is not in effect unless a congestion is
present.
Further I do not believe shaping is supported on Ethernet (some higher end
boxes to have additional QOS implemented in hardware).
Best regards,
Alexei

Subject: Which one should I pick ?
If I have a question:
Configure CBWFQ on R1's Ethernet interface such that it allocates min
bandwidth of 3mbps for VLANA. VLANA traffic should limit to 5mbps and
cannot utilize more physical bandwidth during non-congestion period.
Should I use:
policy-map cbwfq
class VLAND
bandwidth 3000
shape peak 5000000
OR
policy-map cbwfq
class VLAND
bandwidth 3000
police 5000000 937500 1875000 conform-action transmit exceed-action drop
violate-action drop
And if you could give me reasoning on why you pick that one, it would be
greatly appreciated.
Thank you so much in advance,
H.
