=head2 Required MIBs

=over

=item Inherited Classes' MIBs

See L<SNMP::Info::Layer3> for its own MIB requirements.

=back

=head1 GLOBALS

These are methods that return scalar value from SNMP

=over

=item $pa->vendor()

Returns C<'Palo Alto Networks'>.

=item $pa->os()

Returns C<'PANOS'>.

=item $pa->model()

Returns the value of C<panChassisType.0>.

=item $pa->os_ver()

Returns the value of C<panSysSwVersion.0>.

=item $pa->serial()

Returns the value of C<panSysSerialNumber.0>.

=back

=head2 Globals imported from SNMP::Info::Layer3

See documentation in L<SNMP::Info::Layer3> for details.

=head1 TABLE ENTRIES

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

=head2 Overrides

=over

=item $pa->layers()

Returns 01001110.  Palo Alto doesn't report layers, modified to reflect
