dot3StatsDuplexStatus IOD in Dell Networking N1548 Switch

Hi there

Exploring Dell Networking N1548 Switch found that it not support some Dot3StatsEntry. I simple execute in command line snmpwalk -v2c -c public switch and found listed below:

SERVER ~ for i in 1 2 3 4 5 6 7 8 9 10 11 13 16 17 18 19 20 21; do snmpwalk -v2c -c public gw 1.3.6.1.2.1.10.7.2.1.$i.57; done
EtherLike-MIB::dot3StatsIndex.57 = INTEGER: 57
EtherLike-MIB::dot3StatsAlignmentErrors.57 = Counter32: 0
EtherLike-MIB::dot3StatsFCSErrors.57 = Counter32: 0
EtherLike-MIB::dot3StatsSingleCollisionFrames.57 = Counter32: 0
EtherLike-MIB::dot3StatsMultipleCollisionFrames.57 = Counter32: 0
EtherLike-MIB::dot3StatsSQETestErrors.57 = Counter32: 0
EtherLike-MIB::dot3StatsDeferredTransmissions.57 = Counter32: 0
EtherLike-MIB::dot3StatsLateCollisions.57 = Counter32: 0
EtherLike-MIB::dot3StatsExcessiveCollisions.57 = Counter32: 0
EtherLike-MIB::dot3StatsInternalMacTransmitErrors.57 = Counter32: 0
EtherLike-MIB::dot3StatsCarrierSenseErrors.57 = Counter32: 0
EtherLike-MIB::dot3StatsFrameTooLongs.57 = Counter32: 0
EtherLike-MIB::dot3StatsInternalMacReceiveErrors.57 = Counter32: 0
EtherLike-MIB::dot3StatsEtherChipSet.57 = No Such Instance currently exists at this OID
EtherLike-MIB::dot3StatsSymbolErrors.57 = No Such Instance currently exists at this OID
EtherLike-MIB::dot3StatsDuplexStatus.57 = No Such Instance currently exists at this OID
EtherLike-MIB::dot3StatsRateControlAbility.57 = No Such Instance currently exists at this OID
EtherLike-MIB::dot3StatsRateControlStatus.57 = No Such Instance currently exists at this OID

Unfortunately switch do not return values for:

dot3StatsEtherChipSet
dot3StatsSymbolErrors
dot3StatsDuplexStatus
dot3StatsRateControlAbility
dot3StatsRateControlStatus

For me is critical to obtain dot3StatsDuplexStatus. If there any way to obtain Duplex status of an particular port of the N1548 switch via SNMP?

Thanks, Serhiy
