I have a couple of questions relating to configuring traditional FRTS.
1. What is the lowest interval (Tc) available for DLCIs. What is the default and is there any graph anywhere which states these values?
2. Given a CIR of 128 and the line speed is 512, how do I calculate the Bc given that I am not to burst above the provisioned CIR for DLCIs? I am aware of the the relationship between CIR, BC and the Tc but how do I calculate and configure the values? Tc=Bc/CIR.
One of the solutions I have seen related to these questions is below but I don't seem to understand their reasoning:
interface Serial0/0
frame-relay traffic-shaping
frame-relay class REMAINING_BW
frame-relay interface-dlci 204
class DLCI_204
!
map-class frame-relay DLCI_204
frame-relay cir 128000
frame-relay bc 1280
