Hi all:
I'm trying to write a Perl module (for my own use) based on the SNMP module distributed with Net-SNMP.
What I'd like to do is based on a trap number and OID, look up a TRAP-TYPE (v1) definition, and determine what OIDs, data-types, and values that the trap requires.
I'd then be able to build up a call to SNMP::TrapSession::trap() that would get all the required information directly from the MIB file, rather than hard-coding information already in the MIB into my code.
My interface to the module would look something like: sendTrap($$@) $ = enterprise OID of the trap to send $ = specific trap to send @ = array of parameters that are attached to the trap
I haven't found examples of getting information out of the SNMP::MIB tied hash; is what I'm thinking of feasible at all?
It sounds like you want to pull out the VARIABLES line (v1) or OBJECTS line (v2+) from the MIB using the Perl module. Based on what I see in the perl/SNMP/README file, I don't think it's possible. There is no hash entry for those variables.
Here is a bit of code that will pull some data from the hash for a linkDown (.1.3.6.1.6.3.1.1.5.3) which may help you:
#!/usr/bin/perl
use SNMP;
$ENV{'MIBS'} = 'ALL';
&SNMP::initMib();$a = '.1.3.6.1.6.3.1.1.5.3';
print qq/key: $a\n
label: $SNMP::MIB{$a}{label}\n
type: $SNMP::MIB{$a}{type}\n
module: $SNMP::MIB{$a}{moduleID}\n\n"
/;Are you trying to write a program to create test traps based on the MIB?
