I agree with Jim; the MinCIR is the CIR that your provider is giving you and
the CIR is the maximum rate you want the router to burst at on the PVC. You
need this when you have multiple PVCs on the same interface to prevent any
PVC from monopolizing the interface or when you have different port speeds
at the ends of the PVC (a T1 at the central site and a 64K connection on the
remote site).
On a PVC carrying voice, you want to configure your CIR (not the minCIR) to
be equal to the contracted CIR because you don't want to take the risk of
losing your voice packets because of congestion in the FR cloud.

The way I understand it is the burstable port speed equates to CIR and the
minCIR is actually the guaranteed CIR limit from the provider. When shaping,
a congestion notification will throttle the bandwidth back to the minCIR
value.

Subject: FRTS ...CIR vs. MinCIR command
With FRTS what is the difference configuring the CIR versus configuring the
minCIR ???
If I buy a Service from Provider which states that the PVC between Main Site
A and Branch office B the CIR is 64 Kbit/s....I would configure on FRTS the
CIR as 64....but what about MinCIR ???
Tnx for the help
Omar
