mls aggregate-policer burst value

[gatlin007]

Is there a good rule of thumb for selecting the bust parameter on the 3550 in regards so the aggregate-policer command?

mls qos aggregate-policer hero 8000000 1500000 exceed-action drop

As with the policy-map configuration, not all families of Catalyst switches support the entire options list with the mls qos aggregate-policer command. To tie an aggregate policer to a class-map action clause in a policy map, use the following command:

police aggregate aggregate_policer_name

Burst determines the leaky bucket size. It should be large enough to except 1 interval of traffic at your policed rate - to not drop the initial traffic coming into the bucket.

All traffic that overflows the bucket is dropped.

In terms of calculations, check out:

The link holds both IOS and CatOS versions of the policing.
