ABSTRACT:
The Switch includes a port configured to receive a command frame when installed in a switching Fabric. The frame identifies a source device and a destination device in the Switching Fabric, a command, and a read/write flag which indicates if the identified source intends to exercise read-only or write access to the destination device. The Switch also includes a processor coupled to the port. The processor is configured to trap the frame and prevent it from reaching the defined destination device in the switching Fabric if both the source and destination devices are in a read-only zone and the flag indicates that the source intends to write to the destination device. In this manner, read-only zones can be implemented in the Switching Fabric.
