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->fw_mac()
    Returns reference to hash of forwarding table MAC Addresses.

    Some devices don't implement the "BRIDGE-MIB" forwarding table, so we use the "Q-BRIDGE-MIB" forwarding table. Fall back to the "BRIDGE-MIB" if "Q-BRIDGE-MIB" doesn't return anything.

$netgear->fw_port()
    Returns reference to hash of forwarding table entries port interface identifier (iid)

    Some devices don't implement the "BRIDGE-MIB" forwarding table, so we use the "Q-BRIDGE-MIB" forwarding table. Fall back to the "BRIDGE-MIB" if "Q-BRIDGE-MIB" doesn't return anything.

$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
