15.6.3 ML-Series Ethernet Card Performance Monitoring Parameters
Note Unlike E-Series cards, G-Series cards do not have a display of Trunk Utilization statistics, because
G-Series cards are not Layer 2 devices.
15.6.2.3 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 15-9. The parameters are defined in Table 15-10 on
page 15-21.
15.6.3 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.
15.6.3.1 ML-Series Ether Ports Parameters
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 15-11 defines the ML-Series Ethernet card Ether Ports PM parameters.

Parameter Meaning
Link Status Indicates whether the Ethernet link is receiving a valid Ethernet signal
(carrier) from the attached Ethernet device; up means present, and down
means not present.
ifInOctets Indicates the number of bytes received since the last counter reset.
rxTotalPackets Indicates the number of packets received.
ifInUcastPkts Indicates the number of unicast packets received since the last counter
reset.
ifInMulticast Pkts Indicates the number of multicast packets received since the last counter
reset.
ifInBroadcast Pkts Indicates the number of broadcast packets received since the last counter
reset.
ifInDiscards Indicates the number of inbound packets which were chosen to discard,
though no errors had been detected. This prevents them from moving to
a higher-layer protocol. A possible reason for discarding such packets is
to free up buffer space.
ifOutOctets Indicates the number of bytes transmitted since the last counter reset.
txTotalPkts Indicates the number of transmitted packets.
