Hi Dave,
But do the net-snmp agent also keeps the mapping array for its own purpose?
I know some agent keeps an array where it maps all the OID names and the
associated numeric identifiers.
Likewise do net-snmp maintains any such array of all the registered objects?
For example,
{" 1.3.6.1.2.1.2.1", "ifNumber"},
{ " 1.3.6.1.2.1.2.2", "ifTable" },
{" 1.3.6.1.2.1.2.2.1", "ifEntry"},
{" 1.3.6.1.2.1.2.2.1.1", "ifIndex"},
{" 1.3.6.1.2.1.2.2.1.2", "ifDescr"},
....
....
....
Or is there a way to derive this kind of information from the agent?
Thanks,
Siva..

The mapping between numeric OIDs and MIB object names is handled by the
MIB files loaded by the client. See the FAQ entry
"How do I add a MIB to the tools"
for further details.
Note that the information returned by the agent is exactly the same.
regardless of whether or not the relevant MIBs are available to the client.
These MIB files are purely used for how the client application will
*display* the information returned from the agent.
