Using SNMP to Monitor Nexus for CRC

[scubaguy3]

I would like to know what OID to use to monitor CRC and input errors on Nexus 5672 and nexus 3148.

Hi,

The OID commonly used for this purpose is
locIfInCRC 1.3.6.1.4.1.9.2.2.1.1.12
part of the OLD-CISCO-INTERFACES-MIB
 http://snmp.cloudapps.cisco.com/Support/SNMP/do/BrowseOID.do?objectInput=1.3.6.1.4.1.9.2.2.1.1.12&translate=Translate&submitValue=SUBMIT
Unfortunately I do not see this MIB listed as a supported MIB for the Nexus

You may try polling the above MIB, but may not respond.


The next best options

ifInErrors 1.3.6.1.2.1.2.2.1.14
 http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?objectInput=1.3.6.1.2.1.2.2.1.14&translate=Translate&submitValue=SUBMIT&submitClicked=true

and

ifOutErrors 1.3.6.1.2.1.2.2.1.20
 http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=ifOutErrors#oidContent


Please refer the following SNMP Mib objects (ifTable) mapping with router
CLI for these interface counters.

ifInOctets = rx input bytes
ifInUcastPkts = rx unicast packets
ifInNUcastPkts = rx broadcast and multicast packets
ifInDiscards = Not supported
ifInErrors = input errors + runt err + crc err + ecc err + overflow err +
underflow err + sync loss err
ifInUnknownProtos = Not applicable
ifOutOctets = tx output bytes
ifOutUcastPkts = tx unicast packets
ifOutNUcastPkts = tx broadcast and multicast packets
ifOutDiscards =
Bad_etype_drop+if_down_drop+tx_dropped+bad_proto_drop+storm_suppression
ifOutErrors = tx crc errors
ifOutQLen = Not applicable

Hope this will help

Thanks-

Afroz
