Table 2-18 on page 2-93 defines the Ethernet specific Operational
Measurements (OM) supported by the 2xGigE/FC-P2P circuit pack. The
2xGigE/FC-P2P circuit pack supports full duplex mode only, all half duplex
parameters will returned a value of “NA”
OUTFRAMESDISCDS
(Out discarded frames) 0 0
OUTOCTETS
(Out octets) Octets transmitted out of the interface.
Includes GFP headers and payload FCS. NA
OUTOCTETSERR
(In errored octets) 0 NA

Ethernet Specific Operational Measurements
Name Duplex Definition
ALIGNERR
(Align errors) Both The number of frames received that were not an integral
number of octets in length and do not pass the FCS check.
This parameter is not applicable to Gigabit Ethernet, as such
is not supported by the 2xGigE/FC-P2P circuit pack. A value
of “0” is always returned.
FCSERR
(FCS errors) Both The number of frames received that were an integral number
of octets in length and do not pass the FCS check.
SINGLECOLLFR
(Single collision frames) Half The number of times frames were successfully transmitted
after one collision.
This parameter is not applicable to the 2xGigE/FC-P2P
circuit pack, a value of “0” is always returned.
MULTICOLLFR
(Multi collision frames) Half The number of times that frames were transmitted after
multiple collisions (2 to 15 collisions of the frame).
This parameter is not applicable to the 2xGigE/FC-P2P
circuit pack, a value of “0” is always returned.
SQETESTERR
(SQE Test Error) Half Count of times the SQE test error message is generated by
the PLS sublayer.
This parameter is not applicable to the 2xGigE/FC-P2P
circuit pack, a value of “0” is always returned.
