SYNOPSIS

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

        my $class      = $netgear->class();
        print "SNMP::Info determined this device to fall under subclass : $class\n";

DESCRIPTION

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

   Inherited Classes
       SNMP::Info::Layer2 =item SNMP::Info::Entity =item SNMP::Info::LLDP

   Required MIBs
       Inherited Classes' MIBs
           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.

GLOBALS

       These are methods that return scalar value from SNMP

   Overrides
       $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).

   Global Methods imported from SNMP::Info::Layer2
       See documentation in "GLOBALS" in SNMP::Info::Layer2 for details.

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

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

TABLE METHODS

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

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

   Topology information
       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
