Chapter 15 Performance Monitoring
15.6.3 ML-Series Ethernet Card Performance Monitoring Parameters
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,
Packet-over-SONET (POS) Ports, and RPR Span tabbed windows within the card view Performance tab
window. These tabs may vary depending on the card selected.
15.6.3.1 ML-Series Ether Ports Statistics Window
The Ethernet Ether Ports 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. The ML-Series Statistics window also has a Clear button. The
Clear button sets the values on the card to zero, but does not reset the ML-Series card.
During each automatic cycle, whether auto-refreshed or manually refreshed (using the Refresh button),
statistics are added cumulatively and are not immediately adjusted to equal total received packets until
testing ends. To see the final PM count totals, allow a few moments for the PM window statistics to finish
testing and update fully. PM counts are also listed in the ML-Series card Performance > History 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.
ifInErrors
1
The number of inbound packets (or transmission units) that contained
errors preventing them from being deliverable to a higher-layer protocol.
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.
