transceiver-threshold
This command displays the alarm/warning thresholds for temperature, voltage,
bias current, transmit power, and receive power.
Syntax
show interfaces transceiver-threshold [interface]
interface

unit - Unit identifier. (Range: 1)
port - Port number. (SFP+ Ports 25-28
18
)
Default Setting
Shows all SFP interfaces.
Command Mode
Privileged Exec
Command Usage
◆ The switch can display diagnostic information for SFP modules which support
the SFF-8472 Specification for Diagnostic Monitoring Interface for Optical
Transceivers. This information allows administrators to remotely diagnose
problems with optical devices. This feature, referred to as Digital Diagnostic
Monitoring (DDM) in the command display, provides information on
transceiver parameters including temperature, supply voltage, laser bias
current, laser power, received optical power, and related alarm thresholds.
◆ The DDM thresholds displayed by this command only apply to ports which
have a DDM-compliant transceiver inserted.
Example

DDM Thresholds
18. Due to a chip limitation, transceiver data cannot be displayed on ports 1-24.
