35 Inherited Classes' MIBs
36 See SNMP::Info::Layer3 for its own MIB requirements.
37
39 These are methods that return scalar value from SNMP
40
41 $netsnmp->vendor()
42 Returns 'Net-SNMP'.
43
44 $netsnmp->os()
45 Returns the OS extracted from "sysDescr".
46
47 $netsnmp->os_ver()
48 Returns the software version extracted from "sysDescr", along with
49 the Net-SNMP version.
50
51 $netsnmp->uptime()
52 Returns the system uptime instead of the agent uptime. NOTE:
53 discontinuity timers and other Time Stamp based objects are based
54 on agent uptime, so use orig_uptime().
55
56 $netsnmp->serial()
57 Returns ''.

63 These are methods that return tables of information in the form of a
64 reference to a hash.
65
66 Overrides
67 $netsnmp->i_ignore()
68 Returns reference to hash. Increments value of IID if port is to
69 be ignored.

77 In order to cause SNMP::Info to classify your device into this class,
78 it may be necessary to put a configuration line into your snmpd.conf
79 similar to
80
81 sysobjectid .1.3.6.1.4.1.8072.3.2.N
82
83 where N is the object ID for your OS from the "NET-SNMP-TC" MIB (or 255
84 if not listed). Some Net-SNMP installations default to an incorrect
85 return value for "system.sysObjectId".
86
87 In order to recognize a Net-SNMP device as Layer3, it may be necessary
88 to put a configuration line similar to
89
90 sysservices 76
91
92 in your snmpd.conf.
