Errors
Pre-FEC-SYMB (Pre-FEC Symbol) for Fibre Channel 32X/64X, indicates
that FEC symbol errors are corrected and counted once for each 10-bit
symbol; excluding frames in LOCWS.
Pre-FEC-SYMB (Pre-FEC Symbol) for FlexO, indicates FEC symbol
errors are corrected and counted once for each 10-bit symbol.
REI (Remote Error Indication) for Path OAM, indicates that REI are
received from path peer.
REI-L / MS-REI (Remote Error Indicator) for SONET/SDH, indicates that
the M0, M1, or the combination of both M0 and M1 bytes indicate that
one or more BIP violations have been detected. Refer to M0 or M1/Z2
(SONET) on page 714 for more information. For OC-192, also refer to
REI-L Computation Method on page 418.
REI-L (Remote Error Indicator - Line) for WIS, indicates that bits 5
through 8 of the M0 byte contain one pattern from the following binary
range: “0001" through “1000" (1 to 8) (located in the first STS-1 of an
STS-n signal).
REI-P (Remote Error Indicator - Path) for WIS, indicates that bits 1
through 4 of the G1 byte contain one pattern from the following binary
range: “0001" through “1000" (1 to 8) (located in every STS-1 of an
STS-n signal).
REI-P / HP-REI (Remote Error Indicator) for SONET/SDH, indicates that
bits 1 through 4 of the G1 byte contain one pattern from the following
binary range: “0001” through “1000” (1 to 8) (located in every
STS-1/STM-1 of an STS-n/STM-n signal.
REI-V / LP-REI (Remote Error Indicator) for SONET/SDH, is declared
when bit 3 of the V5 byte is set to “1”.
Runt for Ethernet, indicates frames smaller than 64 bytes with an
invalid FCS; 80 bytes for EoE; 82 bytes for PBB-TE.
SEQV (Sequence Violation) for OTU3 with 40 GbE client, indicates that
unexpected sequence is detected.
