gettable method broken or limited ?

I have been trying to get the gettable method working with no success
(sort of).

I am trying to get at a table in the Cisco class based qos mib using
gettable with no success.

All I get is the following error...

 

C:\Perl>perl testthis.pl

Cannot find module: At line 1 in (none)

STORE(SNMP::MIB=HASH(0x19fb740) enterprises.9.9.166.1.1.1
HASH(0x1a4c44c)) : write access to the MIB not implemented

Modification of non-creatable array value attempted, subscript -1 at
C:/Perl/site/lib/SNMP.pm line 694.

 

The code is simple and basically straight from the man page

 

#!/usr/bin/perl

  use SNMP;

  use Data::Dumper;

  use strict;

  #my $mib='CISCO-CLASS-BASED-QOS-MIB';

  my $mibs='ALL';

  &SNMP::loadModules(my $mibs);

  my $hostname="xxx.xxx.xxx.xxx";

  my $comm="somename";

  my $port="161";

  

   my $sess = new SNMP::Session( 'DestHost'   => $hostname,

                                       'Community'   => $comm,

                                       'RemotePort'  => $port,

                                       'Timeout'   => 5000000,

                                       'Version'        => '2',);

  die "Cannot create session: ${SNMP::ErrorStr}\n" unless defined $sess;

  print Dumper($sess->gettable('1.3.6.1.4.1.9.9.166.1.1.1'));

 

If I substitute the above oid for "ifTable" or its oid, the results are
as expected.

If I use the command line "SNMPTABLE" on the same device and oid, the
results are as I would expect.

 

Is it my poor code or gettable/SNMP.PM ?

 

Thanks in advance
