Viewing the Results of a BER Test

You can view the results of a BER test using the controller command:
show controllers T3 slot/port-adapter/port/t1-line-number
where: t1-line-number is 1–28.
You can view the results of a BER test at the following times:
•
•
•
You can view information about a BER test using the controller command:
show controllers T3 slot/subslot/port
where: t1-line-number is 1–28.
Examples follow:

After you terminate the test using the no t1 bert command.
After the test runs completely.
Anytime during the test (in real time).
The example that follows is for a CT3 line card:
Router# show controllers T3 1/0/0
T3 1/0/0 is up.
C2T3 H/W Version : 3, C2T3 ROM Version : 0.79, C2T3 F/W Version : 0.29.0
T3 1/0/0 T1 1
No alarms detected.
Clock Source is internal.
BERT test result (running)
Test Pattern : 2^11, Status : Sync, Sync Detected : 1
Interval : 5 minute(s), Time Remain : 5 minute(s)
Bit Errors(Since BERT Started): 6 bits,
Bits Received(Since BERT start): 8113 Kbits
Bit Errors(Since last sync): 6 bits
Bits Received(Since last sync): 8113 Kbits
explains the output of the preceding command, starting at the arrow:
Interpreting BER Test Results
Explanation
Indicates the current state of the test. In this case, "running"
indicates that the BER test is still in progress. After a test is
completed, "done" is displayed.
Indicates the test pattern you selected for the test (2^11), the
current synchronization state (sync), and the number of
times synchronization has been detected during this test (1).
