1. A method comprising:

  • accessing a database including at least two types of zones present in a fabric, a first type zone specifying devices by Fibre Channel parameters and a second type zone specifying devices by an Ethernet parameter and Fibre Channel parameters, where devices can be coupled to the fabric using either Fibre Channel or Ethernet connections, each zone including at least one device as a member of the zone; and

    responsive to the zones accessed from the database, restricting communications between the devices coupled to the first fabric,wherein the step of restricting communications between the devices includes;

    programming a comparison circuit to evaluate fields in a frame, the fields including a source device address and a destination device address, and to provide an indication that the source device and the destination device can communicate only if the source and destination devices are members of a common first type zone and if both devices are coupled to the fabric using an Ethernet connection, that both devices are members of a common second type zone; and

    evaluating a received frame using the comparison circuit.
