=head1 DESCRIPTION
|
|
|
|
Provides abstraction to the configuration information obtainable from a
|
|
Netgear device through SNMP. See inherited classes' documentation for
|
|
inherited methods.

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.

|
|
|
|
=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
