Hi all,
On one of my QFX10008, I am seeing CRC and BER errors like below:
Feb 20 20:55:41.907 ablab.czk-re0 fpc4 CCL: 1 CRC errors seen on link PE2-Avg-28nm-link-9-17 Feb 21 03:04:03.213 ablab.czk-re0 fpc5 CCL: 1 CRC errors seen on link PE2-Avg-28nm-link-9-17
When I run fabric-related commands, it shows everything is ok; because these errors are not consistently occurring. I see 4-5 occurrence in a day at random times.
Also, today I saw that all the SIB's restarted themselves automatically at the same time and I am not sure what triggered the same. Even after this, I see CRC and BER errors getting reported at around 4-5 per day again.
1. How do I proceed further to resolve this or isolate the issue with FPC/SIB?
2. What does link 9-17 mean in the logs? How do we map this to FPC or SIB link?
Appreciate any help understanding this or if there are any documents that can help me.
