SNMP get vs walk #672

Closed wilpig closed 9 years ago

wilpig commented 9 years ago

I've hit a case with an Eaton CDU that it would not respond to an snmpget but it will a walk. We might need to put a fall back on the snmp function to try a get first and if that fails to try a walk before it declares failure.

[pig@firewall mrtg]# snmpget -v 1 -c pig 10.0.0.9 .1.3.6.1.4.1.534.6.6.7.7.1.1.4.0
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: SNMPv2-SMI::enterprises.534.6.6.7.7.1.1.4.0

[pig@firewall mrtg]# snmpwalk -v 1 -c pig 10.0.0.9 .1.3.6.1.4.1.534.6.6.7.7.1.1.4.0
SNMPv2-SMI::enterprises.534.6.6.7.7.1.1.4.0.1 = INTEGER: 755

That's because you're attempting to get the wrong OID. Look at your results - when you do the walk, it returns the child of the tree that you requested, rather than the exact OID. snmpget is working as expected.
