Performance Monitoring
If the CV-L(NE and FE) falls in the range 51-61 for DS3,then, the user might see discrepancy in the SES
Note
and the UAS-L values. However, ES-L will be in the nearest accuracy. For a few seconds, in a given 10
seconds interval, the number of CV-L counted may not cross the CV count criteria for SES, (due to
system/application limitation for the below mentioned ranges); as a consequence of which there may not
be 10 continuous SES, thus UAS will not be observed.
15.6 Performance Monitoring for Ethernet Cards
The following sections define PM parameters and definitions for the ONS 15454 E-Series, G-Series,
ML-Series, and CE-Series Ethernet cards.
15.6.1 E-Series Ethernet Card Performance Monitoring Parameters
CTC provides Ethernet performance information, including line-level parameters, port bandwidth
consumption, and historical Ethernet statistics. The E-Series Ethernet performance information is
divided into the Statistics, Utilization, and History tabbed windows within the card view Performance
tab window.
15.6.1.1 E-Series Ethernet Statistics Window
The Ethernet Statistics window lists Ethernet parameters at the line level. The Statistics window provides
buttons to change the statistical values shown. The Baseline button resets the displayed statistics values
to zero. The Refresh button manually refreshes statistics. Auto-Refresh sets a time interval at which
automatic refresh occurs.

Number of bytes received since the last counter reset.
Number of unicast packets received since the last counter reset.
The number of inbound packets (or transmission units) that contained
errors preventing them from being deliverable to a higher-layer protocol.
Number of bytes transmitted since the last counter reset.
Number of unicast packets transmitted.

A count of frames received on a particular interface that are an integral
number of octets in length but do not pass the FCS check.
A count of frames received on a particular interface that exceed the
maximum permitted frame size.
