SNMP::Info::Layer3::Pf - SNMP Interface to FreeBSD-Based Firewalls using Pf /Pf Sense

       Max Baker

       Subclass for FreeBSD PF-Based devices

       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".

       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.

        # Let SNMP::Info determine the correct subclass for you.

           or die "Can't connect to DestHost.\n";

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

       These are methods that return tables of information in the form of a reference to a hash.
