Frame-relay trafic shaping

February 22, 2008 @ 5:09 am · Filed under CCIE Study

Hi Frog, IMHO CIR is what we can expect we will get from provider, so if we have to reserve 20 % means (Guarantee) then we will calculate it from CIR and not AR(Total Bandwidth for local loop) and for signalling that is local to service provider, we can calcuate it from AR. Someone, Correct me if I am wrong.

FRTS question folks,
Q1. in QoS class-map statement, if we have to reserve 20% bandwidth - will that be calculated from Frame-relay CIR???? (CIR=95% of BW). I am not sure….
Q2. Also if we have to allocate 20% bandwidth for signaling traffic - will that be calculated from CIR? or Total Bandwidth?
can someone shed some light on this please….
