15.5.3 ML-Series Ethernet Card Performance Monitoring Parameters
Note Unlike the E-Series, the G Series card does not have a display of Trunk Utilization statistics, because the
G-Series card is not a Layer 2 device or switch.
15.5.2.3 G-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 15-20. The listed parameters are defined in Table 15-18 on
page 15-17.
15.5.3 ML-Series Ethernet Card Performance Monitoring Parameters
CTC provides Ethernet performance information for line-level parameters and historical Ethernet
statistics. The ML-Series Ethernet performance information is divided into the Ether Ports and Packet
over SONET/SDH (POS) Ports tabbed windows within the card view Performance tab window. The
following sections describe PM parameters provided for the ML100T-12 and ML1000-2 Ethernet cards.
15.5.3.1 ML-Series Ether Ports Window
The Ether Ports window lists Ethernet PM parameter values for each Ethernet port on the card.
Auto-Refresh sets a time interval at which automatic refresh will occur. The PM values are a snapshot
captured at the time intervals selected in the Auto-Refresh field. Historical PM values are not stored or
displayed.
Table 15-21 defines the ML-Series Ethernet card Ether Ports PM parameters.
Table 15-20 Ethernet History Statistics Per Time Interval
Time Interval Number of Intervals Displayed
1 minute 60 previous time intervals
15 minutes 32 previous time intervals
1 hour 24 previous time intervals
1 day (24 hours) 7 previous time intervals
