NAME
SNMP::Info - OO Interface to Network devices and MIBs through SNMP
VERSION
SNMP::Info - Version 3.68
AUTHOR
SNMP::Info is maintained by team of Open Source authors headed by Eric
Miller, Bill Fenner, Max Baker, Jeroen van Ingen and Oliver Gorwits.
Please visit <https://github.com/netdisco/snmp-info/> for the most
up-to-date list of developers.
SNMP::Info was originally created at UCSC for the Netdisco project
<http://netdisco.org> by Max Baker.
DEVICES SUPPORTED
There are now generic classes for most types of device and so the
authors recommend loading SNMP::Info with AutoSpecify, and then
reporting to the mail list any missing functionality (such as neighbor
discovery tables).
SYNOPSIS
use SNMP::Info;
my $info = new SNMP::Info(
# Auto Discover more specific Device Class
AutoSpecify => 1,
Debug => 1,
# The rest is passed to SNMP::Session
DestHost => 'router',
Community => 'public',
Version => 2
) or die "Can't connect to device.\n";
my $err = $info->error();
die "SNMP Community or Version probably wrong connecting to device. $err\n" if defined $err;
my $name = $info->name();
my $class = $info->class();
print "SNMP::Info is using this device class : $class\n";
# Find out the Duplex status for the ports
my $interfaces = $info->interfaces();
my $i_duplex = $info->i_duplex();
# Get CDP Neighbor info
my $c_if = $info->c_if();
my $c_ip = $info->c_ip();
my $c_port = $info->c_port();
# Print out data per port
foreach my $iid (keys %$interfaces){
my $duplex = $i_duplex->{$iid};
# Print out physical port name, not snmp iid
my $port = $interfaces->{$iid};
print "$port: ";
print "$duplex duplex" if defined $duplex;
# The CDP Table has table entries different than the interface tables.
# So we use c_if to get the map from cdp table to interface table.
my %c_map = reverse %$c_if;
my $c_key = $c_map{$iid};
unless (defined $c_key) {
print "\n\n";
next;
}
my $neighbor_ip = $c_ip->{$c_key};
my $neighbor_port = $c_port->{$c_key};
print " connected to $neighbor_ip / $neighbor_port\n" if defined $neighbor_ip;
print "\n";
}
SUPPORT
Please direct all support, help, and bug requests to the snmp-info-users
Mailing List at
<http://lists.sourceforge.net/lists/listinfo/snmp-info-users>.
DESCRIPTION
SNMP::Info gives an object oriented interface to information obtained
through SNMP.
This module is geared towards network devices. Subclasses exist for a
number of network devices and common MIBs.
The idea behind this module is to give a common interface to data from
network devices, leaving the device-specific hacks behind the scenes in
subclasses.
In the SYNOPSIS example we fetch the name of all the ports on the device
and the duplex setting for that port with two methods -- interfaces()
and i_duplex().
The information may be coming from any number of MIB files and is very
vendor specific. SNMP::Info provides you a common method for all
supported devices.
Adding support for your own device is easy, and takes little SNMP
knowledge.
The module is not limited to network devices. Any MIB or device can be
given an objected oriented front-end by making a module that consists of
a couple hashes. See EXTENDING SNMP::INFO.
REQUIREMENTS
1. Net-SNMP
To use this module, you must have Net-SNMP installed on your system.
More specifically you need the Perl modules that come with it.
DO NOT INSTALL SNMP:: or Net::SNMP from CPAN!
The SNMP module is matched to an install of net-snmp, and must be
installed from the net-snmp source tree.
The Perl module "SNMP" is found inside the net-snmp distribution. Go
to the perl/ directory of the distribution to install it, or run
"./configure --with-perl-modules" from the top directory of the
net-snmp distribution.
Net-SNMP can be found at http://net-snmp.sourceforge.net
Version 5.3.2 or greater is recommended.
Versions 5.0.1, 5.0301 and 5.0203 have issues with bulkwalk and are
not supported.
Redhat Users: Some versions that come with certain versions of
Redhat/Fedora don't have the Perl library installed. Uninstall the
RPM and install by hand.
2. MIBS
SNMP::Info operates on textual descriptors found in MIBs.
If you are using SNMP::Info separate from Netdisco, download the
Netdisco MIB package at
<https://github.com/netdisco/netdisco-mibs/releases/latest/>
Make sure that your snmp.conf is updated to point to your MIB
directory and that the MIBs are world-readable.
DESIGN GOALS
1. Use of textual MIB leaf identifier and enumerated values
* All values are retrieved via MIB Leaf node names
For example SNMP::Info has an entry in its %GLOBALS hash for
``sysName'' instead of 1.3.6.1.2.1.1.5.
* Data returned is in the enumerated value form.
For Example instead of looking up 1.3.6.1.2.1.2.2.1.3 and
getting back 23
SNMP::Info will ask for "RFC1213-MIB::ifType" and will get back
"ppp".
2. SNMP::Info is easily extended to new devices
You can create a new subclass for a device by providing four hashes
: %GLOBALS, %MIBS, %FUNCS, and %MUNGE.
Or you can override any existing methods from a parent class by
making a short subroutine.
See the section EXTENDING SNMP::INFO for more details.
When you make a new subclass for a device, please be sure to send it
back to the developers (via a github pull request or the mailing
list) for inclusion in the next version.
SUBCLASSES
These are the subclasses that implement MIBs and support devices:
Required MIBs not included in the install instructions above are noted
here.
MIB Subclasses
These subclasses implement method to access one or more MIBs. These are
not used directly, but rather inherited from device subclasses.
For more info run "perldoc" on any of the following module names.
SNMP::Info::AdslLine
SNMP Interface to the ADSL-LINE-MIB for ADSL interfaces.
Requires the ADSL-LINE-MIB, down loadable from Cisco.
See documentation in SNMP::Info::AdslLine for details.

See documentation in SNMP::Info::Aggregate for details.

USAGE
Constructor
new()
Creates a new object and connects via SNMP::Session.
my $info = new SNMP::Info( 'Debug' => 1,
'AutoSpecify' => 1,
'BigInt' => 1,
'BulkWalk' => 1,
'BulkRepeaters' => 20,
'IgnoreNetSNMPConf' => 1,
'LoopDetect' => 1,
'DestHost' => 'myrouter',
'Community' => 'public',
'Version' => 2,
'MibDirs' => ['dir1','dir2','dir3'],
) or die;
SNMP::Info Specific Arguments :
AutoSpecify
Returns an object of a more specific device class
(default 0, which means "off")
BigInt
Return Math::BigInt objects for 64 bit counters. Sets on a
global scope, not object.
(default 0, which means "off")
BulkWalk
Set to 0 to turn off BULKWALK commands for SNMPv2 connections.
Note that BULKWALK is turned off for Net-SNMP versions 5.1.x
because of a bug.
(default 1, which means "on")
BulkRepeaters
Set number of MaxRepeaters for BULKWALK operation. See "perldoc
SNMP" -> bulkwalk() for more info.
(default 20)
LoopDetect
Detects looping during getnext table column walks by comparing
IIDs for each instance. A loop is detected if the same IID is
seen more than once and the walk is aborted. Note: This will not
detect loops during a bulkwalk operation, Net-SNMP's internal
bulkwalk function must detect the loop.
Set to 0 to turn off loop detection.
(default 1, which means "on")
IgnoreNetSNMPConf
Net-SNMP version 5.0 and higher read configuration files,
snmp.conf or snmp.local.conf, from /etc/snmp, /usr/share/snmp,
/usr/lib(64)/snmp, or $HOME/.snmp and uses those settings to
automatically parse MIB files, etc.
Set to 1 "on" to ignore Net-SNMP configuration files by
overriding the "SNMPCONFPATH" environmental variable during
object initialization. Note: MibDirs must be defined or Net-SNMP
will not be able to load MIBs and initialize the object.
(default 0, which means "off")
Debug
Prints Lots of debugging messages. Pass 2 to print even more
debugging messages.
(default 0, which means "off")
DebugSNMP
Set $SNMP::debugging level for Net-SNMP.
See SNMP for more details.
