System and method to enable large MTUs in data center ethernet networks

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.

1. A method of configuring a port on a network device, comprising:
receiving at the network device a first frame of information, the first frame comprising a first type-length-value (TLV) and a second TLV; determining that a first field of the first TLV includes first maximum transmission unit (MTU) information, and that a second field of the second TLV includes second MTU information; and configuring a prioritized receive queue of a plurality of prioritized receive queues on the port with a first MTU size based upon the first field.
