Abstract:
1. In a data processing device, a method comprising: providing an exclusive ability to a fibre channel over Ethernet (FCoE) stack to define an Ethertype within an ethertype field of an Ethernet packet with a value “FCoE”; enabling, at an adapter, storage of one or more access control lists (ACLs) containing allowed destination addresses and allowed source addresses; exchanging one or more messages with an Ethernet switch to determine a feasibility of establishing direct communication with other endpoints, wherein determining the feasibility comprises: in response to the definition value for the ethertype field of Ethernet packets not being equal to the value “FCoE” for the non-FCoE stacks and the field value associated with the FCoE stack is “FCoE”, enabling an initiation of a process to connect FCoE endpoints, including an exchange of messages between an endpoint and an Ethernet switch; and allowing direct communication between FCoE endpoints when said FCoE endpoints have a same Zone ID.
