Hi


Bandwidth commands allocates the particular amount of bandwidth you mention or configure over there.


Basically you have the liberty to configure upto 75% of the available interface bandwidth to different classes.


most widelys used with CBWFQ technique..


so while configuring up the same better to watch out for the exact bandwidth value keyed in on the interface to have your alloocation work properly.



policing basically used for limiting the traffic or to control the bursts by dropping them or marking them with different ip precedence or DSCP values.


its very much similar to the rate-limit command applied on the interface level which again uses token bucket system either single or dual based on the configuration parameters.



for more info on above mentioned clis do check these links..
