With the rise of Open Networking, where a user is able to switch out any piece of the stack without vendor lock in (switch, pluggable, NOS, etc…), we have only seen more issues arise when compared with vendor locked solutions. Most of these issues happen at L1 between the switch, the NOS, and the pluggable (cable or optic). Even companies that promote open networking solutions and provide internal testing fall victim to L1 issues. This talk is centered around common L1 issues observed from the field and how some vendors have banded together to eliminate them.
