ddm rx-power

This command is used to configure the thresholds of input power on specified

ports.

ddm rx-power {high | low} {alarm | warning} VALUE

no ddm rx-power {high | low} {alarm | warning}

Default The default value is read from the A2h EEPROM in SFP/SFP+.

Command Mode Interface configuration.

Usage Guideline Only SFP/SFP+ port interfaces 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 no ddm rx-power command will clear configuration and reload the value in

SFP module.

Example The following example shows how to configure rx power low warning threshold

as 0.181 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 event 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 The valid value for the threshold is between 0 ~ 6.5535 mW
