CLI Reference Guide

ddm voltage
This command is used to configure the thresholds of voltage of the specified
ports.
ddm voltage {high | low} {alarm | warning}
VALUE
no ddm voltage {high | low} {alarm | warning}
Default
The default value is read from the A2h EEPROM in SFP/SFP+ ny I2C.
Command Mode
Interface configuration.
Usage Guideline
Only SFP/SFP+ port interfaces with: optical module support DDM; are valid for
this configuration.
This command configures the voltage thresholds on the specified ports, the value
will be converted to a 16-bit format and then written into the SFP module.
It is possible to verify settings by the
show ddm configuration
command.
Thresholds are written to the EEPROM in the SFP/SFP+ transceivers, so
threshold configurations will be stored in the SFP/SFP+ transceivers, if the A2h
EEPROM threshold fields are writable in the SFP vendor’s design. If the
EEPROM’s threshold fields are read-only, the abnormal status detection will be
performed by software instead of the SFP’s alarm/warning flag fields.
Be careful to configure threshold values, please reference the SFP module
vendor’s data sheet for default values and recommended values.
Example
The following example shows how to configure voltage low alarm threshold as
0.005 on interface eth3.1.
Syntax Description
high
High threshold command. When the operating parameter rises above this value,
the action associated with the alarm or the warning is taken.
low
Low threshold command. When the operating parameter falls below this value,
the action associated with the alarm or the warning is taken.
alarm
An alarm even will be generated when the operating parameter is not in the
normal range between the high and low thresholds.
warning
A warning event will be generated when the operating parameter is not in the
normal range between high and low thresholds.
VALUE
Value for threshold. The Valid range is 0~6.55 Volts.
switch#configure terminal
switch(config)# interface eth3.1
Switch(config-if)# ddm voltage low alarm 0.005
% According to the DDM precession definition, closest value 0.005 is chosen.
