## Procedure

> 1. Right-click on the chassis and select Device Summary > Modems from the popup menu. The modems dialog box appears.

> 2. Select Modem System View from the Category drop-down list box.

The CiscoView Monitor Port window displays the following information for a Frame Relay port:

Error Percentage

Traffic

### Error Percentage

Specifies an error rate on the Frame Relay port. To calculate the error rate, use the following formula:

(frCircuitReceivedFECNs + frCircuitReceivedBECNs) /

(frCircuitReceivedFrames + 1) * 100

### Traffic

Specifies the amount of traffic through the Frame Relay port.

CiscoView uses the formula frCircuitSentFrames + frCircuitReceivedFrames to calculate the amount of traffic.
