The following example shows the information of a BER test that is still in progress:
Router# show controller OC12 1/0:1 bert
Interface Serial1/0:1 (DS3 port 1)
BERT information:
State :enabled (sync'd)
Pattern :2^23
Interval :10 minutes
Time remaining :00:01:44
Total errors :0
Time this sync :00:08:10
Errors this sync :0
Sync count :1
Router#
Note When the DS3 is running a BERT, the Total Bit Errors value is not valid if the Status field
is Not Sync.
The following is an example of a screen display from a completed BER test:
Router# show controller OC12 1/0:1 bert
Interface Serial1/0:1 (DS3 port 1)
BERT information:
State :disabled (sync'd, completed)
Pattern :2^23
Interval :10 minutes
Time remaining :00:00:00
Total errors :0
Time this sync :00:09:54
Errors this sync :0
Sync count :1
Router#
Tabl e 8 provides explanations of the BERT display fields in the previous examples:
Table8 BER Test Display Fields
BERT Information Explanation
State: enabled (not synchronized)BER test is active, but the hardware has not currently
synchronized. Errors are counted only when the hardware has
synchronized.
State: enabled (synchronized) BER test is active, and the hardware has synchronized. Any errors
encountered are counted.
State: disabled (not synchronized,
failed) BER test is finished and the test resulted in failure, either because
the hardware never synchronized or the physical layer interface
module (PLIM) declared the test a failure.
State: disabled (synchronized,
completed) BER test is finished because the interval expired.
State: disabled (synchronized,
aborted) BER test is finished as a result of a user request (for example, no
bert)
Pattern Can be any one of the supported BERT patterns.
Interval Can be any value from 1 to 1440 (units are in minutes).
