Transceiver Performance Monitoring
Transceiver Performance Monitoring Overview
The Transceiver Performance Monitoring and Enhanced Diagnostics enables viewing the Digital Optical Monitoring (DOM) parameters for the optics that support enhanced diagnostics. Use the show commands to view the instantaneous values for various PAM4 parameters such as Signal-To-Noise Ratio, Residual Inter Symbol Interference, PAM4 Level Transition Parameters, and other parameters supported on optics interfaces.
Using the Performance Monitoring feature allows EOS to collect and maintain certain performance statistics over a user-defined time. EOS stores data for two intervals: the current interval and the most recently completed interval. When the current interval ends, the data is saved as the previous interval so a new current interval can start, and the old previous interval data discarded.
Configuring Transceiver Performance Monitoring
EOS enables the Digital Optical Monitoring (DOM) on all interfaces and you cannot disable the feature.
switch(config)#performance-monitoring transceiver defaultswitch(config)#interface Ethernet8/1
switch(config-if-Et8/1)#performance-monitoring transceiverswitch(config)#performance-monitoring period 60sThecommand configures the performance monitoring period to 60 seconds across the system. This command supports configuring the performance monitoring period in units of either seconds, minutes, hours or days. For example, use performance-monitoring period 30 minutes to configure the period as 30 minutes, performance-monitoring period 2 hours to configure the period as 2 hours and so on. The default performance-monitoring period is 15 minutes.
Use the no form of these commands to revert the configuration.
100GBASE-FR, 100GBASE-LR and 100GBASE-DR do not have thresholds for enhanced Digital Optical Monitoring (DOM) parameters, so these parameters and their thresholds do not display in the output of show interfaces transceiver dom thresholds command.
