That line looks fine. INTEGER should be exported by default. Please do the following:

Add:

use strict;
use warnings;
[download]

before that line.

Quote the bareword private.

Run it again and post any error output.

Ok, I have changed the code to this:

use strict; 
use warnings;
use Net::SNMP;

my $ip = XXX.XXX.XXX.XXX;

my $SESSION = Net::SNMP->session (-hostname=>$ip, -community=>"private
+");

$SESSION->set_request(-varbindlist=> ['1.3.6.1.4.1.6080.3.1.2.4.0", IN
+TEGER, 1]);

print $SESSION->error();
[download]

When I run that I get the following error: Bareword "INTEGER" not allowed while "strict subs" in use at line 19. If I put quotes around INTEGER, I get the original error of ASN.1 Type Integer unknown.

Mismatched quotes:

'1.3.6.1.4.1.6080.3.1.2.4.0"

Should be:

'1.3.6.1.4.1.6080.3.1.2.4.0'

Your problem was niggling me so I tried it myself.

Other than the $ip value, I used exactly what you have (with the mismatched quote problem fixed).

Here's my code:

#!perl

use strict;
use warnings;

use Net::SNMP;

my $ip = '127.0.0.1';

my $SESSION = Net::SNMP->session (-hostname=>$ip, -community=>"private
+");

$SESSION->set_request(-varbindlist=> ['1.3.6.1.4.1.6080.3.1.2.4.0', IN
+TEGER, 1]);

print $SESSION->error();
[download]

And here's the output:

$ net_snmp_problem.pl
No response from remote host "127.0.0.1"
[download]

As you can see, no problem with INTEGER.

Furthermore, when I ran it without fixing the quotes, I got:

Can't find string terminator "'" anywhere before EOF at ./net_snmp_pro
+blem.pl line 12.
[download]

which suggests that you're posting different code to what you're actually running.

Anyway, if you're still having difficulties, my best advice would be to re-install Net::SNMP.
