=head1 SYNOPSIS

 # Let SNMP::Info determine the correct subclass for you. 
 my $zyxel = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          # These arguments are passed directly on to SNMP::Session
                          DestHost    => 'myhub',
                          Community   => 'public',
                          Version     => 1
                        ) 
    or die "Can't connect to DestHost.\n";

 my $class      = $l2->class();
 print "SNMP::Info determined this device to fall under subclass : $class\n";

=head1 DESCRIPTION

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

=head2 Inherited Classes

=over

=item SNMP::Info::Layer2

=back

=head2 Required MIBs

=over

=item ADSL-LINE-MIB

This MIB assumedly obtainable through ZyXEL or possibly included with your device.

=item Inherited Classes

MIBs listed in SNMP::Info::Layer2 and their inherited classes.

=back

=head1 GLOBALS

These are methods that return scalar value from SNMP

=head2 Overrides

=over

=item $zyxel->vendor()

Returns 'ZyXEL' :)

=item $zyxel->os()

Returns 'ZyXEL' 

=item $zyxel->os_ver()

Culls Version from description()

=item $zyxel->ip()

Returns IP Address of DSLAM.

(B<ipAdEntAddr>)

=item $zyxel->model()

Trys to cull out model out of the description field.

=back

=head2 Global Methods imported from SNMP::Info::Layer2

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

=head1 TABLE ENTRIES

=head2 Overrides

=over

=item $zyxel->i_name()

Returns reference to map of IIDs to port name (B<ifDescr>).

=item $zyxel->i_description()

Returns reference to map of IIDs to human-set port description (profile name).
