Methods and apparatus for performing encryption for data at rest at a port of a network device such as a switch are disclosed. Specifically, when data is received from a host during a write to a storage medium such as a disk, the data is encrypted by the port prior to transmitting the encrypted data to the storage medium. Similarly, when a host attempts to read data from the storage medium, the port of the network device receives the encrypted data from the storage medium, decrypts the data, and transmits the decrypted data to the host. In this manner, encryption and decryption of data at rest are supported by the port of the network device.

Methods and devices are provided for encapsulating FC frames from a network device as Ethernet frames. Preferably, the FC frames represent traffic for a plurality of ports of the network device. The encapsulated Ethernet frames may be input to a conventional network interface card of a personal computer ('PC') or laptop. Therefore, encapsulating the FC frames allows an engineer to use software installed on a conventional PC to troubleshoot problems with a network using FC protocol. According to some aspects of the invention, FC frames may be truncated to various degrees, to allow smaller data frames to be output at an appropriate rate to the analyzing personal computer, laptop, etc.

According to the present invention, methods and apparatus are provided to improve the techniques and mechanisms for forwarding packets at a fiber channel switch. A combined area table/domain table (ATDT) is accessed using destination information associated with a fiber channel packet. Area/port or domain information can be used to address entries in the ATDT. Each entry provides one or more paths to a given destination. Traffic shaping, load balancing, and other policy based forwarding considerations can be applied.
