Transceiver Threshold Configuration
– 416 –
Example
The following example sets alarm thresholds for the transceiver voltage at port 25.
Console(config)interface ethernet 1/25
Console(config-if)#transceiver-threshold voltage low-alarm 4
Console(config-if)#transceiver-threshold voltage high-alarm 2
Console#
show interfaces
transceiver
This command displays identifying information for the specified transceiver,
including connector type and vendor-related parameters, as well as the
temperature, voltage, bias current, transmit power, and receive power.
Syntax
show interfaces transceiver [interface]
interface
ethernet unit/port
unit - Unit identifier. (Range: 1)
port - Port number. (ECS4120-28F SFP+ Ports 25-28

,
Other models: SFP/SFP+ Ports)
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.
Example
Console#show interfaces transceiver ethernet 1/25
