Description

A kind of method, line card and the switching equipment of aging MAC Address
Technical field
The present invention relates to data communication field, especially a kind of method, line card and the switching equipment of aging MAC Address.
Background technology
For each network equipment there are one the MAC Address of 48bit, double layered communication is to be turned by address table to carry out message Hair.When a message is come in from the network equipment, carry out source MAC study first, then with the target MAC (Media Access Control) address in message come Address search is carried out, if there is finding, is forwarded from corresponding port, is carried out if not finding in LAN general Flood.
In case type equipment, MAC address learning can be independently carried out per the port of bracing cable card, if on a bracing cable card The MAC Address learnt is not synchronized on other line cards, and it is the MAC's to receive target MAC (Media Access Control) address on other line cards at this time Message, then message can be flooded forwarding, be just present with well-known unicast flooding at this time, i.e., user, which can see the MAC, has study to arrive, The forwarding but message is still flooded.
In order to solve the problems, such as that well-known unicast message floods across card forwarding, the mac address information learnt on a bracing cable card, Need to be synchronized on other all line cards, Fig. 1 is system schematic of the prior art, be connected to below management engine line card 1, 3 grade line cards of line card 2 and line card, after the MAC Address learnt is uploaded to management engine by line card 2, management engine can by the MAC Location is re-synchronised on line card 1 and line card 3.
Due to the message of long-term miss, meeting automatic aging, so when MAC Address synchronous on other line cards has arrived aging After cycle, so after across the MAC address aging of card synchronization, can be if receiving target MAC (Media Access Control) address at this time by automatic aging The message of the MAC Address, and the problem of be present with well-known unicast flooding.
Current system is synchronous using management engine decision-making+software timing in order to solve the problem of aging across card sync message Strategy.The mac address information is still preserved, it is necessary to which aging informations is waited to be communicated to pipe i.e. after a MAC address aging, on software Engine is managed, whether is deleted by management engine decision-making.If management engine receives MAC address aging and notices and judge the MAC Address It is not to learn on the line card of source, then the MAC Address need not be deleted.Aging line card can be periodically by local aging MAC Address is re-added on hardware, when the MAC Address of aging does not add back hardware again, if the line card just receives The message of this target MAC (Media Access Control) address still can flood forwarding.If source line card due to not receiving hit address table for a long time and It is aging, then the aging information is communicated to management engine, and the management engine synchronous mac address information aging that judges between right and wrong then notices it His line card deletes the mac address information.
With the continuous upgrading of chip, table capacity is increasing, when there is substantial amounts of synchronous MAC Address in environment, this If a little MAC Address persistently hit update address table information without message, will be generated largely every a digestion period On the one hand location aging information can occupy the system communication resource, on the other hand processing needs software to add again, and logic is more multiple It is miscellaneous, sequence problem is easy to cause, the inconsistent grade other problems in complete machine address occurs.
The content of the invention
In order to solve the above-mentioned technical problem, the embodiment of the present invention adopts the following technical scheme that：
A kind of method of aging MAC Address applied in the first line card of switching equipment, comprises the following steps：
