Template:FAQ:Coding 06
From Net-SNMP Wiki
This is usually a sign of the same problem as above - giving
mib2c
the name of the file containing the MIB
(or of the MIB itself), rather than an object within it.
Earlier versions of mib2c
didn't detect this
situation, and rather than report an error, it merrily
constructed a template
for a default starting point of the mib-2
node.
More recent versions issue the error mentioned above instead.
