Errors on Serial interface during E1 BERT test

Hi all,

I am currently running a BERT test on an E1 controller. The "show controller e1 bert" command is showing no errors since I started the test (15 minutes ago).

But I found out, that the serial interface associated to that controller is taking massive amounts of errors during the BERT. Here are the current stats:

"7760818 input errors, 464131 CRC, 523691 frame, 1854450 overrun, 0 ignored, 4918547 abort"

There is currently a loop on my circuit which I am testing against. I figured out that the loop is not visibile on the serial during the BERT.

Here are my two questions:

1. Is it normal that the serial interface is taking errors during the BERT, althouth BERT results itself are looking good?

2. Is it a normal behaviour that the loop is not visible on the serial during the BERT?

Would be happy about any help.

Thanks.

Just saw it might better fit under "Service Provider - MPLS" or somewhere over there.

Maybe some moderator can move it there.

Thanks

You can ignore serial interface statistics during BERT tests.
