摘要： A network switch includes a port coupled to a host, and a profile. The profile includes a key associated with a virtual machine on the host, and information for configuring the port for the virtual machine. The switch receives communication on another port with the key and configures the other port for the virtual machine. A method includes coupling a host with a virtual machine to a port of a network switch, receiving communications from the virtual machine on the port, and creating a profile with a key for identifying data associated with the virtual machine and with information for configuring the switch to route data associated with the virtual machine through the port, receiving communications with the key information at another port, and modifying the information to route data for the virtual machine through the other port.

摘要： An Ethernet device includes receive buffers and transmit buffers of a port, and a processor. The buffers are each associated with a respective class of service. The processor operates to determine a current buffer utilization in a receive buffer, determine that the current buffer utilization is different than a buffer threshold for the receive buffer, determine a data rate limit for the class of service associated with the receive buffer based upon the difference between the current buffer utilization and the buffer threshold, and send a data rate limit frame to another device coupled to the port. The data rate limit frame includes the data rate limit for the class of service.

摘要： A method of configuring a port on a network device includes receiving a frame of information, determining that the frame includes maximum transmission unit (MTU) information, and configuring a prioritized receive queue on the port with an MTU size based on the MTU information. The MTU size is different than another MTU size of another prioritized receive queue on the port. A network interface includes a port, a de-multiplexer coupled to an output or the port, and prioritized receive queues that each have an MTTU size. A first prioritized receive queue has an MTU size different than a second prioritized receive queue.
