=head1 NAME
SNMP::Info::Layer2::Netgear - SNMP Interface to Netgear switches
=head1 AUTHOR
Bill Fenner and Zoltan Erszenyi
=head1 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";
=head1 DESCRIPTION
Provides abstraction to the configuration information obtainable from a
Netgear device through SNMP. See inherited classes' documentation for
inherited methods.
=head2 Inherited Classes
=over
=item SNMP::Info::Layer2
=back
=head2 Required MIBs
=over
=item Inherited Classes' MIBs
MIBs listed in L<SNMP::Info::Layer2/"Required MIBs"> and its inherited
classes.
=back
=head1 GLOBALS
These are methods that return scalar value from SNMP
=head2 Overrides
=over
=item $netgear->vendor()
Returns 'netgear'
=item $netgear->os()
Returns 'netgear'
=item $netgear->model()
Returns description()
=back
=head2 Global Methods imported from SNMP::Info::Layer2
See documentation in L<SNMP::Info::Layer2/"GLOBALS"> for details.
=head1 TABLE METHODS
These are methods that return tables of information in the form of
a reference to a hash.
=head2 Overrides
=over
=item $netgear->fw_mac()
Returns reference to hash of forwarding table MAC Addresses.
Some devices don't implement the C<BRIDGE-MIB> forwarding table, so we use
the C<Q-BRIDGE-MIB> forwarding table. Fall back to the C<BRIDGE-MIB> if
C<Q-BRIDGE-MIB> doesn't return anything.
=item $netgear->fw_port()
Returns reference to hash of forwarding table entries port interface
identifier (iid)
Some devices don't implement the C<BRIDGE-MIB> forwarding table, so we use
the C<Q-BRIDGE-MIB> forwarding table. Fall back to the C<BRIDGE-MIB> if
C<Q-BRIDGE-MIB> doesn't return anything.
