Embodiment 1

[0032] This embodiment describes in detail how to perform MAC address synchronization when a member device in a stack system is a non-master member device.

[0033] see figure 2 , figure 2 It is a schematic flowchart of a method for synchronizing MAC addresses in Embodiment 1 of the present invention. The specific steps are:

[0034] Step 201, when the member devices in the stack system know that they need to synchronize the MAC addresses, they read out the MAC addresses learned by the hardware of the member devices in batches, and use the MAC addresses after deleting the MAC addresses whose corresponding port information is the port number of other member devices as the pending MAC addresses. Synchronized MAC addresses.

[0035] The member device deletes the MAC addresses whose port information is the port number of other member devices from all the MAC addresses read out in batches, that is, excludes the MAC addresses learned on common ports of other member devices thro...

Embodiment 2

[0059] After each member device sends a broadcast packet for synchronizing MAC addresses, other member devices will receive the broadcast packet through the stack port.

[0060] When each member device receives a broadcast message synchronizing the MAC address of other member devices through the stack port, it learns the hardware MAC address according to the content of the received broadcast message. The specific process is as follows:

[0061] When a member device receives a broadcast packet synchronizing the MAC address of another member device through the stack port, it matches the local MAC address entry according to the source MAC address of the broadcast packet and the VLAN ID and port information carried in the broadcast packet. .

[0062] If it matches completely, if the status of the MAC address corresponding to the source MAC address is aging, update it to active status; if the source MAC address and VLAN ID are matched, and the port information corresponding to the...

Embodiment 3

[0069] see image 3 , image 3 It is a schematic diagram of the stacking system in Embodiment 3 of the present invention. image 3 Among them, Slot1, Slot2, and Slot3 form a stack, and Slot2 is the main member device. Slot1 and Slot3 respectively learn several MAC addresses from the aggregation group ID of the combination group where the common port and the aggregation group port are located.

[0070] Take the MAC addresses learned by Slot1 and Slot3 as an example. Referring to Table 1, Table 1 shows the contents contained in the MAC address table of Slot1. Referring to Table 2, Table 2 shows the contents contained in the MAC address table of Slot3.

Abstract

The present application discloses a method for synchronizing Media Access Control (MAC) addresses in a stacking system. The method includes: when a member device learns that MAC addresses need to be synchronized, it reads the MAC addresses to be synchronized in batches, and synchronizes the MAC addresses to be synchronized. The MAC address that needs to be synchronized, when synchronizing the MAC address that needs to be synchronized, constructs a broadcast message to synchronize the MAC address according to the MAC address, the VLAN ID and port information corresponding to the MAC address; the member device receives the MAC address through When receiving a broadcast message, the hardware MAC address is learned according to the content of the broadcast message. Based on the same inventive concept, the present application also proposes a device that can reduce CPU consumption during MAC address synchronization.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for synchronizing a Media Access Control (MAC) address in a stacking system. Background technique [0002] Ethernet switch stacking technology can interconnect multiple switches together to form a distributed switching architecture and operate as a logical switching entity. [0003] From a management and configuration point of view, a distributed switching architecture looks like a switching device; from a performance point of view, each switch in the distributed switching Layer traffic communication services make local forwarding decisions. [0004] Multiple switching devices that support stacking can be connected to each other to form a combined device. We call this combined device a stacking system (Stacking), and each device that forms the Stacking is called a member device (Slot). After multiple Slots form Stacking, it becomes a w...
