Module: CM-FACILITY-MIB
OID (symbolic): CM-FACILITY-MIB::f3FpQosPolicerCouplingFlag
OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.96.1.13
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 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 f3FpQosPolicerCouplingFlag?
This read-create TruthValue enables coupling on the Policer so that tokens which would normally fill the CIR (C) bucket instead spill into the EIR (E) bucket once the C-bucket reaches its committed burst size, letting the E-bucket fill at CIR+EIR. An administrator enables this when the long-term average of yellow-marked traffic should be allowed to exceed a strict EIR-only bound by absorbing unused committed capacity. For example, enabling coupling on a policer for a flow that rarely uses its full committed rate lets its excess traffic borrow that unused capacity instead of being capped strictly at EIR.
