Hi everyone,

While polling the host using snmpwalk and 1.3.6.1.2.1.47.1.1.1.1.7 OID got nothing interesting. But I need to get this info somehow:

show interface ethernet 3/46 transceiver details
Ethernet3/46
    transceiver is present
    type is 10Gbase-ER
    name is CISCO-OPNEXT,INC
    part number is TRS7050EN-S103
    revision is 0012
    serial number is ONT173604QB
    nominal bitrate is 10300 MBit/sec
    Link length supported for 9/125um fiber is 40 km
    cisco id is --
    cisco extended id number is 4

Could you guys point me out regarding the right SNMP OID?

Thanks!

Just guessing may be NX-OS 6.1(4a) doesnt support this feature ( get transceiver TX/RX Power data via SNMP)? Catalyst C3750 switches for instance do that with no problem btw.

Is it OK for snmpwalk to ignor the 'Cannot find module' error?

Bug CSCty93934
Description
Symptom:
Nexus does not have entityPhysical Indexes for a slot/port combination which can be used to query entitySensorValue/entityThreshold values.
This leads to inability to retrieve DOM statistics from SFP transceivers in easy way.

Nexus 7000: No SNMP DOM data
