Example: Configuring Bit Error Rate Testing

Configure a BERT test on a T3 interface. In this example, the run duration lasts for
120 seconds. The configured error rate is 0, which corresponds to a bit error rate of
10
every bit the interface sends is a set to a value of 1.

Tracing Operations of an Individual Router Interface

To trace the operations of individual router interfaces, include the
