- test interface ds0-bert-start ds-fpc/pic/port
Command introduced before JUNOS Release 7.4.
Start a bit error rate test (BERT) on a DS0 interface.
ds-fpc/pic/port — DS0 interface name.
Before starting a BERT, you must disable the interface. To do so, include the disable statement at the [edit interfaces interface-name] hierarchy level. You can run a BERT on only one interface per PIC at a time.
