DGS-6604 mm ddm temperature

ddm temperature
This command is used to configure the thresholds of temperature of the specified
ports.
ddm temperature {high | low} {alarm | warning} VALUE
no ddm temperature {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 temperature 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 temperature high alarm threshold
as 127.994 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 The valid range for the thresholds values is -128 ~ 127.996 Celsius.
switch#configure terminal
switch(config)# interface eth3.1
Switch(config-if)# ddm temperature high alarm 127.994
% According to the DDM precession definition, closest value 127.992 is
chosen.
