If, this is a development effort to monitor or modify device parameters with dependencies on various factors - this needs programming, and Net::SNMP, though not the friendliest, is very powerful.

You could try SNMP::Simple, although the author recommends against it being a starting point. If you just ineed Interface info, Net::SNMP::Interfaces works great.

On request, I'm willing to share code that uses SNMP (perL) for monitoring switches, getting ARP info, and diagnose Spanning-tree issues.

My application is automated testing of the SNMP interface for a piece of equipment my company sells, so it'll probably be pretty rigorous if I'm doing my job correctly :-) Lots of table additions and deletions, that's for sure.

Interesting that you mention Net::SNMP. That's the first thing I looked at, but I stopped looking when I realized that it didn't know anything about MIBs. If I want to get sysDescr.0 without having to know that it's .1.3.6.1.2.1.1.1.0, how do I go about that with Net::SNMP?

Take a look at SNMP::MIB::Compiler.

use SNMP::MIB::Compiler;

my $mib = new SNMP::MIB::Compiler;
$mib->add_path('./mibs', '/usr/share/snmp/mibs');
$mib->add_extension('', '.mib', '.my', '.txt');
$mib->repository('./out');

# only accept SMIv2 MIBs
$mib->{'accept_smiv1'} = 0;
$mib->{'accept_smiv2'} = 1;

# no debug
$mib->{'debug_lexer'}     = 0;
$mib->{'debug_recursive'} = 0;

# store compiled MIBs into files
$mib->{'make_dump'}  = 1;
# read compiled MIBs
$mib->{'use_dump'}   = 1;
# follow IMPORTS clause while compiling
$mib->{'do_imports'} = 1;

# load a precompiled MIB
$mib->load('SNMPv2-MIB');

print $mib->resolve_oid('sysDescr'), ".0\n";

UPDATE: show sysDescr.
