CLI Reference Guide
This command is used to configure the thresholds of input power on specified
ports.
High threshold command. When the operating parameter rises above this value,
the action associated with the alarm or the warning is taken.
Low threshold command. When the operating parameter falls below this value,
the action associated with the alarm or the warning is taken.
An alarm even will be generated when the operating parameter is not in the
normal range between the high and low thresholds.
A warning event will be generated when the operating parameter is not in the
normal range between high and low thresholds.
The valid value for the threshold is between 0 ~ 6.5535 mW
The default value is read from the A2h EEPROM in SFP/SFP+ ny I2C.
Interface configuration.
Only SFP/SFP+ port interfaces with: optical module support DDM; are valid for
this configuration.
This command configures the rx-power 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.
The following example shows how to configure rx power low warning threshold
as 0.181 on interface eth3.1.
