15.5 Performance Monitoring for Ethernet Cards
The following sections define performance monitoring parameters and definitions for the E-Series,
G-Series, and ML-Series Ethernet cards.
15.5.1 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. The following sections describe PM parameters provided for the E100T-G and E1000-2
Ethernet cards.
15.5.1.1 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.

Definition
High-Order Path Errored Second Ratio (HP-ESR) is the ratio of errored
seconds to total seconds in available time during a fixed measurement
interval.
High-Order Path Severely Errored Second Ratio (HP-SESR) is the ratio
of SES to total seconds in available time during a fixed measurement
interval.
High-Order Path Background Block Error Ratio (HP-BBER) is the ratio
of BBE to total blocks in available time during a fixed measurement
interval. The count of total blocks excludes all blocks during SESs.
defines the E-Series Ethernet card Statistics parameters.
Meaning
Link integrity indicator (up means present, and down means
not present).
Number of packets received since the last counter reset.
Number of bytes received since the last counter reset.
Number of packets transmitted since the last counter reset.
Number of bytes transmitted since the last counter reset.
Total number of receive errors.
