Transceiver Performance Monitoring

Transceiver Performance Monitoring Overview

The Transceiver Performance Monitoring and Enhanced Diagnostics enables viewing of the Digital Optical Monitoring (DOM) parameters for the optics that support enhanced diagnostics using the CLI. The show commands are used to view the instantaneous values for various PAM4 parameters like Signal-To-Noise Ratio, Residual Inter Symbol Interference, PAM4 Level Transition Parameters, etc. that such optics support.

With Performance Monitoring feature eos collects and maintains certain performance statistics over a user-defined time period. eos stores data for two intervals, the current interval and the most recently completed interval. When the current interval completes, the data is saved as the previous interval so a new current interval may be started. The old previous interval data is discarded.

Configuring Transceiver Performance Monitoring

The Digital Optical Monitoring (DOM) is always enabled on all interfaces and can’t be disabled via any configuration command.

The Performance Monitoring is disabled on all interfaces by default. The performance-monitoring transceiver default configuration command is used to enable Performance Monitoring on all interfaces across the system.
switch(config)# performance-monitoring transceiver default
The Performance Monitoring can also be enabled on a per interface basis using the performance-monitoring transceiver configuration command.
switch(config)# interface ethernet8/1
switch(config-if-Et8/1)# performance-monitoring transceiver
The Performance Monitoring period can be configured using the performance-monitoring period <period> configuration command.
switch(config)# performance-monitoring period 60s

The above command 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 configuration.

Transceiver Performance Monitoring Limitations

100GBASE-FR, 100GBASE-LR and 100GBASE-DR do not have thresholds of enhanced Digital Optical Monitoring (DOM) parameters, so these parameters and their thresholds will not be displayed in the output of CLI command show interfaces transceiver dom thresholds.

    The Indicator column in the output above gives an indication of where the value lies with respect to its thresholds. Nothing is shown when the parameter is in the expected range between the Low Warn and High Warn thresholds. If the value is greater than or equal to the High Alarm or less than or equal to the Low Alarm, ALARM is shown. If the value is greater than or equal to the High Warn (but less than the High Alarm) or less than or equal to the Low Warn (but greater than the Low Alarm), WARN is shown.

The Performance Monitoring period can be configured using the performance-monitoring period configuration command as described in the configuration section.

    Started: 0:00:12 ago

    This indicates the time the host started the performance monitoring interval.

    Last Update: 0:00:02 ago

    This indicates the last time the host read the diagnostic parameters from the module. The host samples values every six seconds.

    Pre-FEC BER avg, Uncorrected BER avg

    This is the average value so far in the indicated performance monitoring interval.

    Pre-FEC BER min, Uncorrected BER min

    This is the minimum value so far in the indicated performance monitoring interval.

    Pre-FEC BER max, Uncorrected BER max

    This is the maximum value so far in the indicated performance monitoring interval.

    Pre-FEC BER high warn exceeded, Uncorrected BER high warn exceeded, Pre-FEC BER high alarm exceeded, Uncorrected BER high alarm exceeded

    This is the number of times the host read a value which was greater than the indicated threshold. The host reads values and checks exceeded thresholds every six seconds. Please note that this provides only an indication of the actual exceeded count.

    Temperature warn exceeded, Temperature alarm exceeded

    This is the number of times the host read a value which was outside the range of the indicated threshold. The host reads values and checks exceeded thresholds every six seconds. Please note that this provides only an indication of the actual exceeded count.

The Indicator column in the output above gives an indication of where the value lies with respect to its thresholds. Nothing is shown when the parameter is in the expected range between the Low Warn and High Warn thresholds. If the value is greater than or equal to the High Alarm or less than or equal to the Low Alarm, ALARM is shown. If the value is greater than or equal to the High Warn (but less than the High Alarm) or less than or equal to the Low Warn (but greater than the Low Alarm), WARN is shown.

Command Output

Performance Monitoring Period: 0:15:00

This indicates the length of one Performance Monitoring period. 0:15:00 specifies a period of 15 minutes, which is the default value for this parameter. The Performance Monitoring period can be configured using the performance-monitoring period configuration command as described in the configuration section.

Started: 0:00:12 ago

This indicates the time the host started the performance monitoring interval.

Last Update: 0:00:02 ago

This indicates the last time the host read the diagnostic parameters from the module. The host samples values every six seconds.

Pre-FEC BER avg, Uncorrected BER avg

This is the average value so far in the indicated performance monitoring interval.

Pre-FEC BER min, Uncorrected BER min

This is the minimum value so far in the indicated performance monitoring interval.

Pre-FEC BER max, Uncorrected BER max

This is the maximum value so far in the indicated performance monitoring interval.

Pre-FEC BER high warn exceeded, Uncorrected BER high warn exceeded, Pre-FEC BER high alarm exceeded, Uncorrected BER high alarm exceeded

This is the number of times the host read a value which was greater than the indicated threshold. The host reads values and checks exceeded thresholds every 6 seconds. Please note that this provides only an indication of the actual exceeded count.

Temperature warn exceeded, Temperature alarm exceeded

This is the number of times the host read a value which was outside the range of the indicated threshold. The host reads values and checks exceeded thresholds every six seconds. Note that this provides only an indication of the actual exceeded count.
