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 15-15 on page 15-31. The listed parameters are defined in
Table 15-16 on page 15-32.
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 (POS) Ports tabbed windows within the card view Performance tab window.

15.6.3.1 ML-Series Ether Ports Window

Table 15-17 defines the ML-Series Ethernet card Ether Ports PM parameters.

Parameter Definition
ifInOctets Number of bytes received since the last counter reset.
rxTotalPackets Number of packets received.
ifInUcastPkts Number of unicast packets received since the last counter reset.
ifInMulticast Pkts Number of multicast packets received since the last counter reset.
ifInBroadcast Pkts Number of broadcast packets received since the last counter reset.
ifInDiscards The number of inbound packets that were chosen to be discarded even
though no errors had been detected to prevent their being deliverable to a
higher-layer protocol. One possible reason for discarding such a packet
could be to free up buffer space.
ifOutOctets Number of bytes transmitted since the last counter reset.
txTotalPkts Number of transmitted packets.
ifOutUcast Pkts Number of unicast packets transmitted.
ifOutMulticast Pkts Number of multicast packets transmitted.
ifOutBroadcast Pkts Number or broadcast packets transmitted.
dot3StatsAlignmentErrors A count of frames received on a particular interface that are not an integral
number of octets in length and do not pass the FCS check.
dot3StatsFCSErrors 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.
etherStatsUndersizePkts The total number of packets received that were less than 64 octets long
(excluding framing bits, but including FCS octets) and were otherwise
well formed.
etherStatsOversizePkts The total number of packets received that were longer than 1518 octets
(excluding framing bits, but including FCS octets) and were otherwise
well formed. Note that for tagged interfaces, this number becomes 1522
bytes.
