SYNOPSIS

  # Let SNMP::Info determine the correct subclass for you. 
  my $netsnmp = new SNMP::Info(
                           AutoSpecify => 1,
                           Debug       => 1,
                           DestHost    => 'myrouter',
                           Community   => 'public',
                           Version     => 2
                         ) 
     or die "Can't connect to DestHost.\n";
 
  my $class      = $netsnmp->class();

DESCRIPTION

Subclass for Generic Net-SNMP devices

Inherited Classes

SNMP::Info::Layer3

Required MIBs

UCD-SNMP-MIB

NET-SNMP-TC

HOST-RESOURCES-MIB

Inherited Classes' MIBs

See SNMP::Info::Layer3 for its own MIB requirements.

GLOBALS

These are methods that return scalar value from SNMP

$netsnmp->vendor()

Returns 'Net-SNMP'.

$netsnmp->os()

Returns the OS extracted from "sysDescr".

$netsnmp->os_ver()

Returns the software version extracted from "sysDescr", along with the Net-SNMP version.

$netsnmp->uptime()

Returns the system uptime instead of the agent uptime. NOTE: discontinuity timers and other Time Stamp based objects are based on agent uptime, so use orig_uptime().

$netsnmp->serial()

Returns ''.

Globals imported from SNMP::Info::Layer3

See documentation in SNMP::Info::Layer3 for details.

TABLE ENTRIES

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

Overrides

$netsnmp->i_ignore()

Returns reference to hash. Increments value of IID if port is to be ignored.

Ignores loopback

NOTES

In order to cause SNMP::Info to classify your device into this class, it may be necessary to put a configuration line into your snmpd.conf similar to

   sysobjectid .1.3.6.1.4.1.8072.3.2.N
 
 

where N is the object ID for your OS from the "NET-SNMP-TC" MIB (or 255 if not listed). Some Net-SNMP installations default to an incorrect return value for "system.sysObjectId".

In order to recognize a Net-SNMP device as Layer3, it may be necessary to put a configuration line similar to

   sysservices 76
 
 

in your snmpd.conf.
