SYNOPSIS

        # Let SNMP::Info determine the correct subclass for you.
        my $pf = new SNMP::Info(
                               AutoSpecify => 1,
                               Debug       => 1,
                               # These arguments are passed directly to SNMP::Session
                               DestHost    => 'myswitch',
                               Community   => 'public',
                               Version     => 2
                               )
           or die "Can't connect to DestHost.\n";

        my $class      = $pf->class();
        print "SNMP::Info determined this device to fall under subclass : $class\n";

DESCRIPTION

       Subclass for Free-BSD PF-Based devices

LLDP Support

       LLDP Support is included but untested in this Device Class.  It is reported that the
       available CDP/LLDP modules for net-snmp don't work on FreeBSD (on which pfSense is based)
       as they assume certain Linux specific Ethernet structures.  This problem is apparently
       solved on PF based firewall appliances by using the ladvd package, for which a port may be
       found here: <http://www.freshports.org/net/ladvd/>.  I'm not sure if this module ties into
       Net-SNMP or not.

GLOBALS

       These are methods that return scalar values from SNMP

       $pf->vendor()
               Returns 'FreeBSD'

       $pf->model()
           Grabs the os version from "sysDescr"

       $pf->os()
           Returns 'Pf'

       $pf->os_ver()
           Tries to reference $pf->id() to one of the product MIBs listed above.  Will probably
           return a truncation of the default OID for pf-based systems
           "enterprises.12325.1.1.2.1.1".
