etherStatsPkts256to511Octets The number of packets received, including error packets, that are
256–511 octets in length.
etherStatsPkts512to1023Octets The number of packets received, including error packets, that are
512–1023 octets in length.
etherStatsPkts1024to1518Octets The number of packets received, including error packets, that are
1024–1518 octets in length.
etherStatsUndersizePkts The number of packets less than 64 octets long that have a valid
FCS.
fcStatsLinkRecoveries The number of link recoveries.
fcStatsRxCredits The number of current receive buffer to buffer credits.
fcStatsTxCredits The number of current transmit buffer to buffer credits.
fcStatsZeroTxCredits This is a count that increments when the FC/FICON Tx credits
go from a nonzero value to zero.
gfpStatsLFDRaised The number of loss of frame delineation (LFD) raised.
gfpStatsRoundTripLatencyUSec Round trip delay for the end-to-end Fibre Channel transport in
microseconds.
gfpStatsRxCRCErrors The number of packets received with a payload FCS error.
gfpStatsRxCSFRaised Received GFP loss of client character synchronization
(LOCCS).
gfpStatsRxDistanceExtBuffers The number of receive buffer credit for GFP-T (valid only if
distance extension is enabled).
gfpStatsRxMBitErrors The received multibit errored core header count (cHEC).
gfpStatsRxSBitErrors The received single-bit errored cHEC.
gfpStatsRxSblkCRCErrors The number of packets received with a payload FCS error. Sblk
stands for super block in the GFP payload.
gfpStatsRxTypeInvalid Received invalid type.
gfpStatsTxDistanceExtBuffers The number of transmit buffer credit for GFP-T (valid only if
distance extension is enabled).
ifInBroadcastPkts The number of packets delivered to a higher sublayer and
addressed to a broadcast address at this sublayer.
ifInDiscards The number of inbound packets that were chosen to be discarded
even though no errors were detected, to prevent them from being
deliverable to a higher-layer protocol. One possible reason for
discarding such a packet could be to free buffer space.
ifInErrors The number of inbound packets (or transmission units) that
contained errors preventing them from being delivered to a
higher-layer protocol.
ifInErrorBytePkts The number of received packets with an error symbol detected.
ifInFramingErrorPkts The number of received packets with a control symbol other than
an error detected.
