You have such a list and snmpwalk is a command line tool? then write a wrapper for that tool that loads this list in a hash and parses the output like this: 
use strict;
use warnings;

my %lookup = ( 'SNMPv2-SMI::enterprises.54321.1.1.1' => 'number of udp
+ connections');

# data can be a filehandle with the output generated 
# by File::Temp
while (my $line = <DATA>) {
        chomp $line;
        my ($oid, $cnt) = $line =~ m{ \A (.*) \s = \s INTEGER: \s ([+-
+]?\d+) \z}xms;
        $oid = $lookup{$oid} if defined $lookup{$oid};
        print "$oid, $cnt\n";
}

__DATA__
SNMPv2-SMI::enterprises.54321.1.1.1 = INTEGER: 0
SNMPv2-SMI::enterprises.54321.1.1.2 = INTEGER: 1
SNMPv2-SMI::enterprises.54321.1.1.3 = INTEGER: 1
SNMPv2-SMI::enterprises.54321.1.1.5 = INTEGER: 1
SNMPv2-SMI::enterprises.54321.1.1.8 = INTEGER: -1
SNMPv2-SMI::enterprises.54321.1.1.9 = INTEGER: 1
SNMPv2-SMI::enterprises.54321.1.1.12 = INTEGER: 0
SNMPv2-SMI::enterprises.54321.1.1.13 = INTEGER: 0
