The CiscoView Monitor Port window displays the following information for a frame relay port:
Specifies an error rate on the port. The error rate is calculated using the following formula:
(frCircuitReceivedFECNs + frCircuitReceivedBECNs) /
(frCircuitReceivedFrames + 1) * 100
Specifies the amount of traffic through the Frame Relay port. The displayed amount of traffic is not the same as what is shown by the show frame pvc command entered at the router. Instead, the displayed value is the difference between the sent and received frames in the circuit.
(To calculate the amount of traffic, CiscoView adds the following MIB values: frCircuitSentFrames + frCircuitReceivedFrames.)
