Hi,
I have problem when doing IPExpert WB 4.0
Using the minimum configuration passible in applying the map-class,
make sure it is applied to all PVCs. Use the following guidelines in
defining Bc, Be, CIR, and MinCIR within your map-class:
a.The Frame Relay service provider is guaranteeing 32Kbps of traffic.
b. The Frame Relay access being provided by the service provider has a
link capacity of 128Kbps.
c. Set the excess burst value by comparing CIR and total link capacity.
d. Set the Bc to 1/8 of the locally configured CIR.
Configure Frame-Relay traffic shaping:
a. The PVC should adapt to received BECNs and if enough BECNs are
received, the eventual traffic rate should be 16Kbps.
b. Set Bc to 8Kbps and Be to 64Kbps.
c. Considering the value of Bc, set the appropriate value of the CIR.
Ensure that all routers can ping their own Frame-Relay interfaces.

My problem is the Be is correct ?
