17.7 FEC PM Parameter Definitions
Table 17-28 defines the MXP_MR_2.5G, MXPP_MR_2.5G, TXP_MR_10E, TXP_MR_10E_C, and
TXP_MR_10E_L card FEC PM parameters. For more information, see the “17.2 Transponder and
Muxponder Card Performance Monitoring” section on page 17-2.
ifInJunkInterPkts The number of interpacket gaps between valid start symbols
during which a symbol other than idle is detected, including
packets of length 1–8 octets.
ifInMulticastPkts The total number of multicast frames received error-free.
ifInOctets The number of bytes received since the last counter reset.
ifOutBroadcastPkts The number of packets requested by higher-level protocols and
addressed to a broadcast address at this sublayer, including those
not transmitted.
ifOutDiscards The number of outbound packets that were chosen to be
discarded even though no errors had been detected to prevent
their being transmitted. One possible reason for discarding such
a packet could be to free buffer space.
ifOutMulticastPkts The number of multicast frames transmitted error-free.
ifOutOctets The number of bytes transmitted since the last counter reset.
InvalidCRCError A count of invalid cyclic redundancy checks (CRCs).
mediaIndStatsRxFramesBadCRC The number of received frames with a CRC error.
mediaIndStatsRxFramesTooLong The number of received frames that are too long.
mediaIndStatsRxFramesTruncated The number of received frames that are too small.
mediaIndStatsTxFramesBadCRC The number of transmitted frames with a CRC error.
Running Disparity Count A count of errors that affect the disparity of the received data
stream.
rxControlFrames The number of MAC control packets that are type 0x8808 and
contain at least 64 octets in length.
rxFrames A count of the number of frames received without errors.
rxLinkReset (Only for FC Mode) A count of the received link resets.
rxPauseFrames The number of received 802.x paused frames.
rxTotalPkts The number of received packets.
rxUnknownOpcodeFrames Number of packets of at least 64 octets in length and type
0x8808, with opcode not equal to 1.
Time Last Cleared A time stamp indicating the last time statistics were reset.
txBytes A count of the number of bytes transmitted from the frame since
the last counter reset.
txFrames A count of the number of transmitted frames.
txTotalPkts The number of transmitted packets.
