all the interface IP aliases configured on the Device.

=cut

__PACKAGE__->has_many( device_ips => 'App::Netdisco::DB::Result::DeviceIp', 'ip' );

=head2 vlans

Returns the C<device_vlan> entries for this Device. That is, the list of VLANs
configured on or known by this Device.

=cut

__PACKAGE__->has_many( vlans => 'App::Netdisco::DB::Result::DeviceVlan', 'ip' );

=head2 ports

Returns the set of ports on this Device.

=head2 modules

Returns the set chassis modules on this Device.

=cut

__PACKAGE__->has_many( modules => 'App::Netdisco::DB::Result::DeviceModule', 'ip' );

=head2 power_modules

Returns the set of power modules on this Device.

=head2 port_vlans

Returns the set of VLANs known to be configured on Ports on this Device,
either tagged or untagged.

The JOIN is of type "RIGHT" meaning that the results are constrained to VLANs
only on Ports on this Device.

Returns the set of wireless IDs known to be configured on Ports on this
Device.

=cut

__PACKAGE__->has_many(
    wireless_ports => 'App::Netdisco::DB::Result::DevicePortWireless',

=head2 powered_ports

Returns the set of ports known to have PoE capability

=cut

    community => 'App::Netdisco::DB::Result::Community', 'ip');

=head1 ADDITIONAL METHODS

=head2 is_pseudo

Returns true if the vendor of the device is "netdisco".

}

=head2 renumber( $new_ip )

Will update this device and all related database records to use the new IP
C<$new_ip>. Returns C<undef> if $new_ip seems invalid, otherwise returns the
Device row object.
