show system pluggable diagnostics
This command displays diagnostic information about SFP and SFP+ pluggable
transceivers, which support Digital Diagnostic Monitoring (DDM).
Different types of pluggable transceivers are supported in different models of switch. See
your switch’s Datasheet for more information about the models of pluggables that your
switch supports.

Mode
User Exec and Privileged Exec
Usage
For a stacked configuration, if this command is entered on the stack master, it will display
information about the pluggable transceivers for all the stack members. A stack member
heading will be displayed to distinguish different pluggable transceiver information for
every stack member.
Modern optical SFP and SFP+ transceivers support Digital Diagnostics Monitoring (DDM)
functions.
Diagnostic monitoring features allow you to monitor real-time parameters of the
pluggable transceiver, such as optical output power, optical input power, temperature,
laser bias current, and transceiver supply voltage. Additionally, RX LOS (Loss of Signal) is
shown when the received optical level is below a preset threshold. Monitor these
parameters to check on the health of all transceivers, selected transceivers or a specific
transceiver installed in a switch.
Examples
To display detailed information about all pluggable transceivers installed on a standalone
switch, use the command:
Parameter
Description
The ports to display information about. The port list can be:
■
a switch port (e.g. port1.0.12)
■
a continuous range of ports separated by a hyphen,
e.g. port1.0.1-1.0.24
■
a comma-separated list of ports and port ranges,
e.g. port1.0.1,port1.0.4-1.2.24.
