Starting And Stopping A Bert Test; Table 22: Bert Capabilities By Interface Type - Juniper JUNOS 10.1 - CONFIGURATION GUIDE 1-2010 Configuration Manual

JUNOS 10.1 Network Interfaces Configuration Guide
Table 22 on page 148 shows the BERT capabilities for various interface types.

These limitations do not apply to channelized IQ interfaces. For information about
BERT capabilities on channelized IQ interfaces, see "Channelized IQ and IQE
Interfaces Properties" on page 402.

Starting and Stopping a BERT Test

Before you can start the BERT test, you must disable the interface. To do this, include
the
After you configure the BERT properties and commit the configuration, begin the
test by issuing the
