NAME¶
SNMP::Info::Layer3::Pf - SNMP Interface to FreeBSD-Based Firewalls using Pf /Pf
Sense
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.
Inherited Classes¶
- SNMP::Info::Layer3
- SNMP::Info::LLDP
Required MIBs¶
- FOKUS-MIB
- Inherited Classes' MIBs
- See "Required MIBs" in SNMP::Info::Layer3 for its own MIB
requirements.
See "Required MIBs" in SNMP::Info::LLDP for its own
MIB requirements.
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".
