Meter Counters
The 7210 SAS E maintains following counters for meters within the system for granular billing
and accounting. Each meter maintains the following counters:
•
•
Meter Modes
The 7210 SAS E supports following meter modes:
•
•
In SrTcm the CBS and MBS Token buckets are replenished at single rate i.e. CIR where as in case
of TrTcm CBS and MBS buckets are individually replenished at CIR and PIR rates, respectively.
Color Aware Policing
The 7210 SAS E supports Color Aware policing at the network ingress, where as at service ingress
policing is color blind. In color aware policing user can define the color of the packet using the
classification and feed those colored packets to the meter. A color aware meter would treat those
packets with respect to the color defined.

•
•
The profile marked by the meter is used to determine the packets eligibility to be enqueued into a
buffer at the egress (when a slope policy is configured at the egress).

Counters for packets or octets marked as in-profile by meter
Counters for packets or octets marked as out-of-profile by meter
SrTcm: Single Rate Three Color Marking
TrTcm; Two Rate Three Color Marking
If the packet is pre-colored as in-profile then depending on the burst size of the packet
meter can either mark it in-profile or out-profile.
If the packet is pre-colored as out-profile then even if the packet burst is lesser than the
current available CBS, it would not be marked as in-profile and remain as out-profile.
If the packet burst is higher than the MBS then it would be marked as Red and would be
dropped by meter at ingress.
