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();
 print "SNMP::Info determined this device to fall under subclass : $class\n";

DESCRIPTION¶

Subclass for Generic Net-SNMP devices

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 ''.

TABLE ENTRIES¶

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

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.
