Re: Is it possible to retrieve oid from mib node name

Hi Dave,

Is there an api (function call) in net-snmp to do that? If not,  is mib2c 
compiler source code available anywhere? After the mib file loaded by 
net-snmp, I want to register individual mib node and its corresponding 
handler function using its node name instead of oid (if I don't run mib2c 
first), is it possible to do that directly and is there an existing api to 
do that? If not, if there is an api that can return oid based on the node 
name, from where I can still register the handler function at the end in 
two steps. Again, all of this is for the purpose of avoiding using mib2c.

Thanks.

The node names within a single MIB module must be unique.
As must all node names within "official" IETF MIBs.

It's not strictly necessary for node names in private MIBs to
be globally unique, but it's relatively uncommon for the same
name to appear in two different MIBs.

It is definitely possible to retrieve an OID using the syntax
    MIB-NAME::mibNode

It is *usually* possible to retrieve an OID using the bare node name
(with a small risk of getting the wrong node, if there happen to be
two different versions in the list of loaded MIBs).

Yes - the standard lookup routines will handle this quite happily.
The MIB::node syntax is handled automatically,  the bare node
name might work straight off, or you may need to explicitly enable
it using the '-IR' command-line option (or equivalent)
   Suck it and see.
