Note To terminate a BERT test during the specified test period, use the no bert command.
You can view the results of a BERT test at the following times:
• After you terminate the test using the no bert command.
• After the test runs completely.

Loopback on VCoP Smart SFP
VCoP smart SFP supports two types of loopback configurations:
• Local loopback - In local loopback, the transmitting signal is looped back to the receiver signal.
• Network loopback - In network loopback, the receiving signal is looped back to the transmitting signal.
You can configure loopback on VCoP smart SFP at two levels:
