 # Let SNMP::Info determine the correct subclass for you. 
 my $netgear = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          DestHost    => 'myswitch',
                          Community   => 'public',

Provides abstraction to the configuration information obtainable from a Netgear device through SNMP. See inherited classes' documentation for inherited methods.

MIBs listed in "Required MIBs" in SNMP::Info::Layer2 and its inherited classes.

See "Required MIBs" in SNMP::Info::Entity for its MIB requirements.

See "Required MIBs" in SNMP::Info::LLDP for its MIB requirements.

These are methods that return scalar value from SNMP

$netgear->vendor()
Returns 'netgear'
$netgear->os()
Returns 'netgear'
$netgear->model()
Returns concatenation of $e_model and $e_hwver if Entity MIB present, otherwise returns description()
$netgear->os_ver()
Returns OS Version.
$netgear->serial()
Returns Serial Number if available (older FS switches have no accessible serial number).

See documentation in "GLOBALS" in SNMP::Info::Layer2 for details.

See documentation in "GLOBALS" in SNMP::Info::Entity for details.

See documentation in "GLOBALS" in SNMP::Info::LLDP for details.

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

$netgear->interfaces()
Uses the i_name() field.

Based upon the software version devices may support Link Layer Discovery Protocol (LLDP).

$netgear->hasCDP()
Returns true if the device is running LLDP.
$netgear->c_if()
Returns reference to hash. Key: iid Value: local device port (interfaces)
$netgear->c_ip()
Returns reference to hash. Key: iid Value: remote IPv4 address

If multiple entries exist with the same local port, c_if(), with the same IPv4 address, c_ip(), it may be a duplicate entry.

If multiple entries exist with the same local port, c_if(), with different IPv4 addresses, c_ip(), there is either a non-LLDP device in between two or more devices or multiple devices which are not directly connected.

Use the data from the Layer2 Topology Table below to dig deeper.

$netgear->c_port()
Returns reference to hash. Key: iid Value: remote port (interfaces)
$netgear->c_id()
Returns reference to hash. Key: iid Value: string value used to identify the chassis component associated with the remote system.
$netgear->c_platform()
Returns reference to hash. Key: iid Value: Remote Device Type
