SYSTEM AND METHOD FOR AUTOMATED DCB CONFIGURATION OF ACCESS SWITCHES

摘要

A system and method of automated Data Center Bridging (DCB) configuration of an access switch includes a control unit, a memory, and a port configured to couple the access switch to a peer device. The control unit is configured to operate the port according to a state machine including a DCB disabled state, a DCB downstream state, and a DCB upstream state. When the port is in the DCB disabled state, the control unit exchanges network traffic on the port without any DCB extensions. When the port is in the DCB upstream state, the control unit exchanges network traffic on the port using DCB extensions based on the DCB configuration and receives the DCB configuration from the peer device. When the port is in the DCB downstream state, the control unit exchanges network traffic on the port using the DCB extensions and transmits the DCB configuration to the peer device.

1. An access switch comprising:
a control unit; a memory coupled to the control unit; and a port coupled to the control unit and configured to couple the access switch to a networked device; wherein the control unit is configured to:
operate the port according to a state machine including a data center bridging (DCB) disabled state, a DCB downstream state, and a DCB upstream state;transition the port from the DCB disabled state to the DCB downstream state when a DCB packet is received on the port;transition the port from the DCB downstream state to the DCB upstream state when a configuration packet received on the port indicates that the networked device is an upstream device selected from a group consisting of a switch, a router, and a repeater; andtransition the port from the DCB upstream state to the DCB downstream state when the configuration packet indicates that the networked device is an end station.
