Usage Guideline
Only SFP/SFP+ port interfaces with optical modules, with transceiver monitoring capability, are valid
for this configuration.
This command configures the voltage thresholds on the specified port. The value will be stored both
in the system and in the SFP/SFP+ transceivers and be converted to the 16-bit format and then
written into the SFP module.
If the SFP module configured does not support the threshold change, the user-configured threshold is
just stored in the system and the displayed value will be the user-configured threshold. If there is no
user-configured threshold, the displayed value will always reflect the factory preset value defined by
the vendor.
The no form of this command has the effect to clear the configured threshold stored in system. It does
not change the threshold stored in the SFP/SFP+ transceivers. Use the no form of this command to
prevent threshold values in newly inserted SFP/SFP+ transceivers from being altered.
Example
This example shows how to configure the low alarm voltage threshold as 0.005 on interface eth3/0/1.
Switch# configure terminal
Switch(config)# transceiver-monitoring voltage eth3/0/1 low alarm 0.005
Switch(config)#
