15.6.4 CE-Series Ethernet Card Performance Monitoring Parameters
15.6.4 CE-Series Ethernet Card Performance Monitoring Parameters
CTC provides Ethernet performance information for line-level parameters and historical Ethernet
statistics. The CE-Series Ethernet performance information is divided into the Ether Ports and POS Ports
tabbed windows within the card view Performance tab window. The following sections describe PM
parameters provided for the CE-100T-8 and CE1000-4 Ethernet cards.
15.6.4.1 CE-Series Ether Ports Statistics Parameters
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 15-14 defines the CE-Series Ethernet card Ether Ports PM parameters.
gfpStatsRxTypeInvalid Indicates the number of receive packets dropped due to Client Data
Frame user payload identifier (UPI) error.
gfpStatsRxCRCErrors Indicates the number of packets received with a payload FCS error.
gfpStatsLFDRaised Indicates the count of core HEC CRC multiple bit errors.
Note This count is only of eHec multiple bit errors when in frame.
This can be looked at as a count of when the state machine goes
out of frame.
gfpStatsCSFRaised Indicates the number of GFP client signal fail frames detected at the
GFP-T receiver.
mediaIndStatsRxFrames
Truncated
Indicates the number of received frames that are too long. The
maximum is the programmed maximum frame size (for VSAN support).
If the maximum frame size is set to default, then the size is the
2112 byte payload plus the 36 byte header, which is a total of
2148 bytes.
mediaIndStatsRxFramesToo
Long
Indicates the number of received frames with a CRC error.
mediaIndStatsRxShortPkts Indicates the number of received packets that are too small.
