test interface e1-bert-start
Syntax
test interface e1-bert-start interface-name
Release Information
Command introduced before Junos OS Release 7.4.
Description
Start a bit error rate test (BERT) on an E1 interface.
Options
interface-name | — | Interface name: e1-fpc/pic/port or ce1-fpc/pic/port <:channel> |
Additional Information
Before starting a BERT, you must disable the interface. To do this, 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. |
