15.6.4 CE-Series Ethernet Card Performance Monitoring Parameters
15.6.4.1 CE-Series Card Ether Port 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 CE-Series Statistics window also has a Clear button. The
Clear button sets the values on the card to zero, but does not reset the CE-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 CE-Series card Performance > History window.
Table 15-21 defines the CE-Series card Ethernet port parameters.

Parameter Definition
Time Last Cleared A time stamp indicating the last time statistics were reset.
Link Status Indicates whether the Ethernet link is receiving a valid Et hernet signal
(carrier) from the attached Ethernet device; up means present, and down
means not present.
ifInOctets Number of bytes received since the last counter reset.
rxTotalPkts Number of received packets.
ifInUcastPkts Number of unicast packets received since the last counter reset.
ifInMulticastPkts Number of multicast packets received since the last counter reset.
ifInBroadcastPkts 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 s uch a packet
could be to free buffer space.
ifInErrors The number of inbound packets (or transm ission 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.
ifOutDiscards1 Number of outbound packets which were chosen to be discarded even
though no errors had been detected to prevent their transmission. A possible
reason for discarding such packets could be to free up buffer space.
ifOutErrors1Number of outbound packets or transmission units that could not be
transmitted because of errors.
ifOutUcastPkts2 Number of unicast packets transmitted.
ifOutMulticastPkts2Number of multicast packets transmitted.
ifOutBroadcastPkts2Number of broadcast packets transmitted.
dot3StatsAlignment
Errors2
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.
