Nexus 7000: No SNMP DOM data

peteroseneff · ‎07-07-2015

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.
