802.1BR based message processing method and device

[0023] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Aiming at the problem that the packet cache chip of the existing data center switch supports the source ECID, but there are defects, the embodiment of the present application provides a packet processing method based on 802.1BR, which can be cascaded Set the same group ID for the cascading port, and carry the group ID corresponding to the cascading port in the inbound direction in the packet header of the message received from the cascading port; in this way, for the message sent from the cascading port, the packet can be judged Check whether the group ID carried in the header is the same as the group ID of the cascading port corresponding to the outbound direction, and if so, add the source ECID t...
