Problems solved by technology

[0004] To solve this problem, the MAC copy function may be set on the user-side port, so that the MAC table can learn the actual corresponding MAC+VLAN entries in the upstream traffic, so that the downstream traffic can directly query the L2 entries and go through the L2 forwarding process. The first method is an example of several MACs cooperating with each other to jointly implement a service. If the several MACs that complete this service are not synchronized, the service may be interrupted.
[0005] In addition, N:1VLAN mapping and other functions may also have several MACs cooperating with each other to complete a service together
[0006] However, there are several MAC services that cooperate with each other in the above-mentioned services. If the MAC entries are not synchronized, the service will be interrupted.

Embodiment Construction

[0058]In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0059] The present invention aims at the problem in the prior art that if the MAC entries are not synchronized among several MAC entries that cooperate with each other, the service will be interrupted. A method and device for aging processing of interrupted media access control MAC entries.

[0060] Such as figure 1 As shown, the method for aging processing of media access control entries of the present invention includes:

[0061] Step 11, forming a MAC table with at least two media access control (MAC) entries that cooperate with each other; wherein, the MAC entry is composed of a MAC address and a VLAN address;

[0062] Step 12, determining a reference aging MAC entry according to the MAC table;

[0063] Step 13, setting the reference aging MAC tabl...

Abstract

The invention provides a method and a device for aging processing of a media access control (MAC) table entry. The method comprises the following steps of: forming an MAC table from at least two MAC entries of a service which are matched with each other; determining a reference aging MAC table entry according to the MAC table; and setting the reference aging MAC table entry to participate in the normal aging, and aging all MAC table entries in the MAC table when the reference aging MAC table entry is aged. Through the scheme, a plurality of MAC table entries which are matched with one another are simultaneously aged, so the service corresponding to the plurality of MAC table entries which are matched with one another is not interrupted.

Description

technical field [0001] The invention relates to the two-layer forwarding technology of communication equipment in the field of communication, in particular to a method and a device for aging processing of MAC (Media Access Control, Media Access Control) entries. Background technique [0002] In network applications, several MACs cooperate with each other to implement a service. In this case, the coordinated MACs need to take effect and age at the same time like one MAC. If several MACs age separately, it may cause out-of-synchronization among several MACs, resulting in service interruption. [0003] For example, in order to distinguish the network layer or service type, the user-side port and the network-side port are often distinguished on the switch, and the user-side port is connected through QinQ (IEEE 802.1Q closed tunnel protocol) technology and flexible Qos (quality of service) technology Classify different traffic, add or modify the VLAN (Virtual Local Area Network)...
