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 peer 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;when the port is in the DCB disabled state, the control unit is configured to exchange network traffic on the port without any DCB extensions;when the port is in the DCB upstream state, the control unit is configured to exchange network traffic on the port using DCB extensions based on a DCB configuration and receive the DCB configuration from the peer device; andwhen the port is in the DCB downstream state, the control unit is configured to exchange network traffic on the port using the DCB extensions based on the DCB configuration and transmit the DCB configuration to the peer device.
