Now that T263019 is done, traffic is flowing on that interface, and revealing CRC errors:

Faulty cable or optic. Feel free to replace without draining traffic away. Ping me if any issue.

I replaced the sfp+ at cr1-eqiad xe-3/2/1 cleared the interface statistics on that port. Let's leave this open a few days to see if anything changes.

@XioNoX it appears a new fiber will need to be run. I will get to this next week. Do we need to schedule any downtime? The total time offline is 1 minute (long enough for me to swap out fiber on both ends).

No need to schedule anything. Thanks.

replaced the cable, gave it the same cable number, removed the old fiber. Cleared the interface statistics on cr1.

No new errors since I replace the fiber. Resolving this
