(1) Not available for XFP transceivers
(2) Not available for SFP and SFP+ transceivers
Notice:
Thresholds that trigger a high alarm, low alarm, high warning, or low warning are set by the transponder vendors. Generally, a high alarm or low alarm indicates that the optics module is not operating properly. This information can be used to diagnose why a transceiver is not working.
