Embodiment
For technical problem, technical scheme and advantage that the present invention will be solved is clearer, will combine accompanying drawing and specific embodiment to be described in detail below.
The present invention is directed in the prior art; In the business that several MAC work in coordination; If it is asynchronous between the MAC clauses and subclauses; Can cause the problem of this service disconnection, a kind of method and device that makes the medium access control MAC address entries burin-in process that these many MAC address entries corresponding service that cooperatively interact can not interrupt is provided.
As shown in Figure 1, the method for medium access control list item burin-in process of the present invention comprises:
Many the MAC clauses and subclauses that this embodiment provides are by the aging simultaneously method of MAC clauses and subclauses (being the aging MAC address entries of benchmark) wherein, make in the business that several MAC work in coordination, and are synchronously aging between the MAC clauses and subclauses, can not cause this service disconnection.
Wherein, above-mentioned steps 11 can specifically be realized by following mode:
111) at least two MAC that cooperatively interact of business are identical but MAC clauses and subclauses that VLAN is different are formed said MAC table; Wherein, at least two MAC is identical but MAC clauses and subclauses that VLAN is different comprise: the identical but VLAN of the MAC of at least two MAC clauses and subclauses has nothing in common with each other, and perhaps the MAC of at least two MAC clauses and subclauses is identical but vlan section is identical; Wherein, when the identical VLAN of the MAC of MAC clauses and subclauses is also identical, can be regarded as same MAC clauses and subclauses, can be according to the normal aging flow processing;
112) at least two VLAN that cooperatively interact of business are identical but MAC clauses and subclauses that MAC is different are formed said MAC table; Wherein, at least two VLAN is identical but MAC clauses and subclauses that MAC is different comprise: the identical but MAC of the VLAN of at least two MAC clauses and subclauses has nothing in common with each other, and perhaps the VLAN of at least two MAC clauses and subclauses is identical but the MAC part is identical; Wherein, when the identical VLAN of the MAC of MAC clauses and subclauses is also identical, can be regarded as same MAC clauses and subclauses, can be according to the normal aging flow processing;
113) the MAC clauses and subclauses of at least two switch ports themselves that cooperatively interact of business being learnt are formed said MAC table.
Certainly, the mode of several the MAC clauses and subclauses that cooperatively interact of business being formed a MAC table is not limited to above-mentioned three kinds of modes mentioning, can also some MAC clauses and subclauses that cooperatively interact be formed a MAC table according to the mode of self-defined setting.
In addition, also can realize in above-mentioned steps 12 by following several kinds of modes:
121) in said MAC table, select MAC clauses and subclauses arbitrarily according to said MAC Address or VLAN address, as the aging MAC address entries of benchmark; MAC clauses and subclauses as comprising in the MAC table are MAC1+VLAN1, MAC2+VLAN2, MAC3+VLAN3 Can select arbitrary MAC clauses and subclauses wherein according to MAC Address, as select the MAC clauses and subclauses at MAC1 place, i.e. MAC1+VLAN1, this MAC1+VLAN1 is exactly the aging MAC address entries of benchmark; Certainly, also can be, as selected VLAN3 according to VLAN address choice arbitrary MAC clauses and subclauses wherein, i.e. MAC3+VLAN3, this MAC3+VLAN3 is exactly the aging MAC address entries of benchmark;
122) the up-to-date MAC clauses and subclauses of learning are set as the aging MAC address entries of benchmark; As the up-to-date MAC clauses and subclauses of learning of the port that switch is set are as the aging MAC address entries of benchmark, and original MAC clauses and subclauses (being MAC address entries) be the subordinate clauses and subclauses in the MAC table, and these up-to-date MAC clauses and subclauses of learning are exactly the benchmark MAC address entries that wears out so.
Generally, the MAC table is deposited a plurality of MAC clauses and subclauses with the form of chained list, and each MAC address entries in this MAC table is a node in this chained list, the respectively corresponding MAC clauses and subclauses of this each MAC address entries;
