The fields within the meter entry are as follows:
- Meter Identifier is a 32-bit unsigned integer identifying meter

- Counters are incremented whenever a meter process a packet
A meter band consists of the following fields:
- Band Type, how a packet is to be processed.
- Rate, the lowest rate at which the meter band can apply
- Burst, defines the granularity of the meter band
- Counter, are incremented when a packet is processed by the band
- Type Specific Arguments, are used with some band types to define additional instructions
