Subclass for Generic Net-SNMP devices
See SNMP::Info::Layer3 for its own MIB requirements.
See SNMP::Info::LLDP for its own MIB requirements.
These are methods that return scalar value from SNMP
Returns 'Net-SNMP'.
Returns the OS extracted from sysDescr.
sysDescr
Returns the software version extracted from sysDescr, along with the Net-SNMP version.
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().
Returns ''.
See documentation in SNMP::Info::Layer3 for details.
See documentation in SNMP::Info::LLDP for details.
These are methods that return tables of information in the form of a reference to a hash.
Returns reference to hash. Increments value of IID if port is to be ignored.
Ignores loopback
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.
NET-SNMP-TC
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.
To install SNMP::Info, copy and paste the appropriate command in to your terminal.
