3 - CIR
The Committed Information Rate (CIR) option specifies the data rate that the Frame Relay service has guaranteed to
provide.
This value must be set to the same as the value provided by the Frame Relay network provider. If the Frame Relay
network provider supplies values for Bc and T only, simply calculate the CIR value by using the following formula: CIR
= Bc/T.
Default:
[0 k]
Range:
0 to 2048 Kbps
Considerations:
When changing the CIR option for this PVC, the PVC must be toggled (disable – enable option 7. State) before
the new value will take effect.
The value of 0 indicates that there is no commitment on the data rate.
The actual CIR may exceed the configured CIR because only complete frames are
transmitted. Frames will not be broken to fit within CIR when the upper limit is met, the
final frame will be transmitted in full. The only time this does not happen is when traffic
exceeds CIR + EIR, in which case the frame which would cause CIR to be exceeded will not
be transmitted.
The only restriction is that CIR + EIR > 0
4 - EIR
The Excess Information Rate (EIR) option specifies the data rate that the Frame Relay service indicates may be available
for this PVC.
This value must be set to the same as the value provided by the Frame Relay network provider.
Default:
["link_speed"]
Range:
0 to 2048 Kb, "link_speed"
Considerations:
When changing the EIR option for this PVC, the PVC must be toggled (disable – enable option 7. State) before
the new value will take effect.
When EIR = 0, no excess burst data is allowed to be transmitted. If EIR is non-zero, bursting is allowed.
The only restriction is that CIR + EIR > 0
