Managing and Troubleshooting the Versalar Switch Router 150006-16 302768-C Rev 00Starting or Stopping BERT on a ChannelIf you enable the generation of bit errors at a consistent rate, you can compare thenumber of errors transmitted to the number received in a loopback test.Conducting a BERT allows you to validate or troubleshoot connections.You must enable BERT mode to conduct this test. The default setting is disabled.To enable or disable BERT mode, go to the logical line test or T1 test prompt(for example, logical-line-test/ft1/2/1/5/6 or t1-test/t1-2/1/4) and enter thefollowing command:bert-mode {enabled | disabled}The following example shows how to disable and reenable a BERT on slot 2,connector 1, FT1 channel 5:t1-test/2/1/5# bert-mode disabledt1-test/2/1/5# bert-mode enabledt1-test/2/1/5#Resetting Local BERT Counters for a ChannelTo reset a BERT to incorporate changes to the BERT parameter settings, go to thelogical line or T1 test prompt (for example, logical-line-test/ft1/2/1/5/6 or t1-test/t1-2/1/4) and enter the following command:bert-reset {no-action | reset}no-action does not reset the BERT. This is the default pattern.reset restarts the BERT using the current parameter settings.The following example shows how to reset a BERT on slot 2, connector 1,T1 channel 4:t1-test/t1-2/1/4# bert-reset resett1-test/t1-2/1/4#Viewing BERT ResultsTo display your test results, enter the following command from any BCC prompt:show logical-line bert-stats
