I have a link that went down for what appears to be my fault? When I run the diag, it shows I'm not sending light? Why would that be? Any ideas?
FWIW, if I set the int to disable, commit and enable, commit, it comes up for 1 second and then goes down again. I've never seen this scenario before. Thanks for any troubleshooting tips!
