    摘要: 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.

    摘要: Methods and apparatus for encapsulating a packet or frame for transmission in a storage area network are disclosed. A packet or frame compatible with a standard protocol employed in the storage area network is received or generated. The packet or frame is then encapsulated with a virtual storage area network identifier. The packet or frame may further be encapsulated with at least one of a TTL value, MPLS information, and a type of traffic to be carried by the packet or frame. For instance, the type of traffic to be carried by the packet or frame may include Ethernet, Fibre Channel, and Infiniband. Once encapsulated, the encapsulated packet or frame is sent over the storage area network. For instance, the encapsulated packet or frame may be generated as well as transmitted by a switch over an inter-switch link in the storage area network.

    摘要: Methods and devices are provided for non-disruptive monitoring of network traffic through one or more ports of a Fibre Channel network device. Preferred embodiments of the invention are used in conjunction with the switched port analyzer (“SPAN”) and/or remote SPAN (“RSPAN”) features. SPAN mode operation allows traffic through any Fibre Channel interface of a network device to be replicated and delivered to a single port on the same network device. Ingress SPAN allows the monitoring of some or all packets that ingress a specified port or ports. Egress SPAN allows the monitoring of some or all packets that egress a specified port or ports. RSPAN allows the delivery of the replicated traffic to a port on a remote network device. Filtering may be applied, for example, to SPAN packets having selected virtual storage area network numbers.
