Embodiment Construction

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0028] figure 2 A flow chart showing a data packet processing method for Ethernet according to an embodiment of the present invention, including the following steps:

[0029] Step S10, determining that MAC address drift occurs;

[0030] Step S20, sending the drifted data packet to the CPU of the switch in the Ethernet to learn the MAC address; and

[0031] Step S30, the ASIC chip of the switch stops learning the MAC address, and stops the continued forwarding of the drifted data packets.

[0032] In the data packet processing method, when it is judged that a loop error occurs, the learning of the MAC address by the ASIC chip is terminated, and the continuous forwarding of the drifted data packet is terminated, so the broadcast storm caused by the loop is avoided. Therefore, problems such as protocol disconnection caused by loops ...

Abstract

The invention provides a processing method and devices which are used on Looped network data packet, the method comprises the following steps: judging that MAC address happens drift, upwards sending a data packet which is drifted to a CPU learning MAC address of an exchanger in the Looped network, leading an ASIC chip of the exchanger to terminate the learning MAC address, and terminating continuous transmission of the drifted data packet. The invention provides a reliable processing method for broadcast storm which is caused by an Looped network exchanger which produces a loop, which dramatically lightens the problems of protocol chain breaking which is caused by the loop and the like, and can not influence other port users when loop happens on a port.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data packet processing method and device for Ethernet. Background technique [0002] Currently, in the field of Ethernet switches, ASIC (Application Specific Integrated Circuits, Application Specific Integrated Circuits) technology has been widely used in Ethernet switch devices. In Layer 2 / Layer 3 switching, the ASIC chip usually adopts the method of learning MAC (Media Access Control, Media Access Control) address, and then synchronizes to the CPU of the switch, so that MAC address learning is faster. In the field of Layer 2 switches, ASIC is a hardware chip specially used for data exchange, while CPU is specially used for control and does not participate in data forwarding. The ASIC chip and the CPU chip are two chips with different functions, and at least one ASIC chip and one CPU chip are included in a switching system. [0003] However, in the current field of Ethernet...
