15.5.2 G-Series Ethernet Card Performance Monitoring Parameters
Note Line utilization numbers express the average of ingress and egress traffic as a percentage of capacity.
Note The E-Series Ethernet card is a Layer 2 device or switch and supports Trunk Utilization statistics. The
Trunk Utilization statistics are similar to the Line Utilization statistics, but shows the percentage of
circuit bandwidth used rather than the percentage of line bandwidth used. The Trunk Utilization statistics
are accessed via the card view Maintenance tab.
15.5.1.3 E-Series Ethernet History Window
The Ethernet History window lists past Ethernet statistics for the previous time intervals. Depending on
the selected time interval, the History window displays the statistics for each port for the number of
previous time intervals as shown in Table 15-17. The listed parameters are defined in Table 15-15 on
page 15-14.
15.5.2 G-Series Ethernet Card Performance Monitoring Parameters
CTC provides Ethernet performance information, including line-level parameters, port bandwidth
consumption, and historical Ethernet statistics. The G-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 G1000-4 and G1K-4
Ethernet cards.
