test interface e3-bert-start

 

Syntax

Release Information

Command introduced before Junos OS Release 7.4.

Description

Start a bit error rate test (BERT) on an E3 interface.

Options

e3-fpc/pic/portE3 interface name.

Additional Information

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.

Note

Due to hardware limitations of the framer used in IQ PICs, BERT is not supported in unframed mode on the interface and may return false positive results. BERT in unframed mode is supported on Enhanced IQ (IQE) PICs.
