Configuring Frame Relay 8-11Figure 8-4 Frame Relay DLCI Record[A],[D],[B],[C] from Main MenuWhen Changes Take EffectChanges to this file take effect when the associated physical port is updated by one ofthe methods described under When Changes Take Effect at the Port on page 8-5 earlierin this chapter. A change can be implemented on line by exiting the record ([F3]), thenopening the associated physical Port record and pressing [F7] to update the port.1 Some formulae that might help in determining these values are:BC >= 8 times maximum packet size.BE <= BC multiplied by [(line speed/CIR) minus 1].Committed Information Rate(CIR) is the data throughput rate that the network agrees to support under normal con-ditions.Committed Burst Size(BC ) is the maximum amount of data that the network agrees to transfer under normalconditions within the time period defined by B C/CIR.
