- assigning one physical VLAN per network
- assigning one MAC prefix per network, so that every NIC attached to this

The end-user is allowed to create only networks of flavor ``MAC_FILTERED`` and
``PHYSICAL_VLAN``. The administrator is able to create any of the above flavors
``DEFAULT_ROUTING_TABLE``, ``DEFAULT_MAC_PREFIX``, ``DEFAULT_BRIDGE``, ``DEFAULT_MAC_FILTERED_BRIDGE``
are all configurable settings in ``/etc/synnefo/20-snf-cyclades-app-api.conf``. 'pool' is used
to denote that a link or MAC prefix will be allocated from the corresponging Pool.
The administrator is able to create any of the above flavors
and override their default values by explicitly passing mode, link, etc.. using
the `snf-manage network-create` command. Currently only ``MAC_FILTERED`` and
``PHYSICAL_VLAN`` can use existing pools and cannot be overriden.
``PHYSICAL_VLAN`` can use existing pools and cannot be overriden.
