Нi. Operated device CRS125-24G-1S-RM version OC 6.20. When disconnecting the fiber from the SFP-module there is a drop port. When connected the fiber to the module, re-plug the module, the port is not alive. Please tell me possible cause and solution for this problem. Also on this version of the OS there is the problem. If you disabled SFP-port through the web-interface then impossible unlock him use the touch panel on the device. How i can solve this problem? Thank you.
