Module: CM-FACILITY-MIB
OID (symbolic): CM-FACILITY-MIB::cmQosPolicerProfileCouplingFlag
OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.39.1.10
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-create
Description: This object allows specification of Policer Coupling Flag. When coupling is enabled, tokens that would normally be added to the C-bucket are passed to the E-bucket only once the CIR bucket has reached its CBS level. Therefore under this condition the E-bucket is being filled at the rate of CIR + EIR. Normally the long term average of frames declared yellow, which is bounded by the EIR. Coupling is a function to allow the long term average of frames declared yellow to be bounded by CIR + EIR. This allows a higher volume of yellow frames to be delivered/received if the arrival of green marked frames is low. Tokens from the E-bucket do NOT get passed to the C-bucket once the EBS level has been reached. Enabling coupling in combination with a provisioned EIR of 0 allows for a single rate three color marking (srTCM) algorithm to be established. In this situation the E-bucket is filled at the CIR rate in the case the C-bucket is filled to its CBS level.
What is cmQosPolicerProfileCouplingFlag?
This read-create TruthValue enables coupling on a QoS policer profile, which, per its description, redirects tokens that would normally refill the CIR (C) bucket into the EIR (E) bucket once the C-bucket has reached its CBS level, letting the E-bucket fill at CIR+EIR when coupling is on. An administrator enables it when the long-term average of excess (yellow) traffic should be allowed to grow beyond the plain EIR bound as long as the committed bucket stays full. For example, a provider offering bursty best-effort capacity above a guaranteed rate would enable coupling so unused committed capacity effectively extends the excess allowance instead of being wasted.
