It optionally, may include the current configuration parameter of multiple aggregation groups in the configuration parameter that message of negotiation request carries. After main equipment receives the message of negotiation request, for each aggregation group, it can be joined according to the configuration of the aggregation group received The configuration parameter and preset configuration parameter negotiation rules of the aggregation group in number, main equipment, after the negotiation for determining the aggregation group Configuration parameter.It is including the configuration parameter of an aggregation group in the configuration parameter that the embodiment of the present application is carried with message of negotiation request Example is introduced, other situations are similar therewith.

Optionally, configuration parameter may include the maximum MAC number and aging policy of global maximum MAC number, aggregation group.

In an implementation, aging policy may include the global aging type supported (such as without aging type, absolute time elder Change type, without flow aging type etc.), aggregation group the aging type and the aging type that uses of aggregation group supported.If polymerization The aging type that group uses is the long aging type of absolute time, then aging policy further includes the aging duration of aggregation group.If polymerization The aging type that group uses is no flow aging type, then aging policy further includes the ageing time of aggregation group and adopting for aggregation group The sample period.

In a kind of feasible implementation, message of negotiation request may include type of message (MSG (English: Message) Type) field, message length (MSGlength) field, test serial number (MSGnum) field, global maximum safe MAC number (total max secure-mac count) field, global aging type (aging-type support) field supported, Aging type (aging-type) field that aggregation group mark (group identity) field, aggregation group use, aggregation group Sampling period (aging-interval) field of ageing time (aging-value) field and aggregation group.In addition, negotiating request Message can also include other fields (such as device identification field), and the embodiment of the present application is not construed as limiting.It as shown in Table 1, is this Apply for a kind of example for message of negotiation request that embodiment provides.

Table one

Step 202, the negotiation response message that main equipment is sent is received.

Wherein, negotiate to carry the configuration parameter after negotiating in response message.

In an implementation, main equipment is according to the configuration parameter and preset configuration parameter of the configuration parameter, main equipment received Negotiation rules after determining the configuration parameter after negotiating, can send the negotiation response message of configuration parameter to standby equipment.Its In, negotiate to carry the configuration parameter after negotiating in response message.It, can be to this after standby equipment receives the negotiation response message Negotiate response message to be parsed, the configuration parameter after obtaining the negotiation carried in the negotiation response message.

Step 203, MAC Address synchronization process is carried out according to the configuration parameter after negotiation.

It in an implementation, can be by this after standby equipment obtains the configuration parameter after the negotiation carried in the negotiation response message The configuration parameter on ground is revised as the configuration parameter after negotiating, to be carried out at MAC Address synchronization according to the configuration parameter after negotiation Reason and MAC address aging processing.In this way, configuration parameter can be consistent in standby equipment and main equipment, to prevent in MAC Due to the inconsistent caused various problems of configuration parameter during the synchronization process of location.

Optionally, when main equipment detects that itself configuration parameter changes, main equipment can also be sent out to standby equipment Notification message is sent, which is used to indicate standby equipment and carries out handling through consultation for configuration parameter.Standby equipment receives the notice and disappears After breath, step 201 can be executed to main equipment and send message of negotiation request,

The embodiment of the present application also provides a kind of method of synchronous MAC Address, this method is applied to main equipment.Such as Fig. 3 institute Show, specific step is as follows.

Step 301, the message of negotiation request that standby equipment is sent is received.

Wherein, the standby current configuration parameter of equipment is carried in message of negotiation request.

In an implementation, the synchronous function of safe MAC is enabled in the aggregation interface of a certain aggregation group of standby equipment as technical staff After capable of or modifying to the corresponding configuration parameter of the aggregation group, standby equipment can send message of negotiation request to main equipment, or Person, standby equipment can also send message of negotiation request to main equipment after the notification message for receiving main equipment transmission.Wherein, The standby current configuration parameter of equipment is carried in the message of negotiation request.Wherein, configuration parameter includes global configuration parameter sum The configuration parameter of the aggregation group.After main equipment receives the message of negotiation request, which can be parsed, Obtain the configuration parameter current for equipment of message of negotiation request carrying.

Step 302, according to configuration parameter, the local configuration parameter and preset configuration parameter negotiation rules received, Determine the configuration parameter after negotiating.

In an implementation, configuration parameter negotiation rules can be previously stored in main equipment, which can To be rule of thumb configured by technical staff.The current configuration of standby equipment that main equipment obtains message of negotiation request carrying is joined After number, it can be determined according to the configuration parameter, local preset configuration parameter and preset configuration parameter negotiation rules of standby equipment Configuration parameter after negotiation.

It optionally, include global maximum MAC number, the maximum MAC number of each aggregation group and each aggregation group for configuration parameter The case where aging policy, it is that main equipment determines the configuration parameter after negotiating the specific process is as follows: determine receive it is global most The first minimum value in big MAC number and the maximum MAC number of the local overall situation, the first minimum value is maximum as the overall situation after negotiating MAC number；For each aggregation group, the maximum MAC number for determining the aggregation group received and local preset aggregation group are most The second minimum value in big MAC number, using the second minimum value as the maximum MAC number after the negotiation of the aggregation group；For each poly- It is combined, by the aging policy of the aggregation group stored in this equipment, as the aging policy after negotiation.

Wherein, the parameter of aging policy may include the global aging type supported (such as without aging type, absolute duration Aging type, without flow aging type etc.), aggregation group the aging type and the aging type that uses of aggregation group supported.If poly- Being combined the aging type used is the long aging type of absolute time, then the parameter of aging policy further includes the aging duration of aggregation group. If the aging type that aggregation group uses is no flow aging type, when the parameter of aging policy further includes the aging of aggregation group Between and aggregation group sampling period.

In an implementation, after main equipment gets the standby current configuration parameter of equipment and local configuration parameter, for the overall situation Maximum MAC number, main equipment can determine the in the maximum MAC number of the overall situation and local preset global maximum MAC number of standby equipment One minimum value, and using the first minimum value as the maximum MAC number of the overall situation after negotiating.For example, the maximum MAC number of the overall situation of standby equipment is 10000, the maximum MAC number of the overall situation configured in main equipment is 9500, then the maximum MAC number of the overall situation after negotiating is 9500.

For each aggregation group, main equipment can configure in the maximum MAC number of the aggregation group of standby equipment and this equipment The aggregation group maximum MAC number in, determine the second minimum value.Then, after using the second minimum value as the negotiation of the aggregation group Maximum MAC number.For example, the maximum MAC number of the aggregation group 2 of standby equipment is 2000, the maximum of the aggregation group 2 configured in main equipment MAC number is 3000, then the maximum MAC number after the negotiation of aggregation group 2 is 2000.

For each aggregation group, main equipment can gather the aging policy of the aggregation group stored in this equipment as this Aging policy after the negotiation being combined.For example, being directed to aggregation group 2, the aging type configured in standby equipment is no flow aging, always The change time is 10 minutes, the sampling period is 1 minute；The aging type configured in main equipment is absolute time aging type, aging Time is 20 minutes, then the aging type of the aggregation group 2 after negotiating is absolute time aging type, ageing time is 20 minutes.

Optionally, the priority of each aging type can also be previously stored in main equipment.Wherein, each aging type is excellent First grade can be rule of thumb configured by technical staff.For example, the priority of not aging type is 1, absolute time aging class Type priority is 2, and the priority of no flow aging type is 3, and the value of priority is bigger, and priority is higher.For each polymerization Group, main equipment can select the old of highest priority in the aging type for the aggregation group that main equipment and standby equipment are supported Change type, as the aging type of the aggregation group after negotiation, and by the ageing time of the aggregation group stored in this equipment and Ageing time and sampling period of the sampling period as the aggregation group after negotiating.

For example, for aggregation group 2, the aging type that main equipment is supported be not aging type, absolute time aging type and Without flow aging type, the currently used aging type of main equipment is no flow aging type, and ageing time is 10 minutes, sampling Period is 2 minutes.For the aging type that standby equipment is supported for absolute time aging type and without flow aging type, main equipment is current The aging type used is no flow aging type, and ageing time is 20 minutes, and the sampling period is 1 minute.Then for aggregation group 2, in aging type that main equipment and standby equipment are supported (i.e. absolute time aging type and without flow aging type), priority For highest aging type without flow aging type, that is, the aging type of the aggregation group 2 after negotiating is no flow aging type, aging Time is 10 minutes, and the sampling period is 2 minutes.

Step 303, the configuration parameter after negotiating is stored, and sends the negotiation response message of configuration parameter to standby equipment.

In an implementation, after main equipment determines the configuration parameter after negotiating, the configuration parameter after negotiation can be stored in It stores in equipment, and sends the negotiation response message for carrying the configuration parameter after negotiating to standby equipment, in this way, main equipment and standby Equipment MAC Address synchronization process can be carried out according to the configuration parameter after negotiation and MAC address aging is handled.Wherein, negotiate to ring Answer the message format of message can be identical as the message format of message of negotiation request, can not also be identical, the embodiment of the present application is not It limits.Based on above-mentioned processing, the configuration parameter of main equipment and standby equipment can be consistent, to prevent same in MAC Address It walks in treatment process due to configuration parameter inconsistent the problem of causing.

Optionally, if main equipment does not receive the negotiation that a certain standby equipment is sent by the aggregation interface of a certain aggregation group Request message, then main equipment can be determined that the aggregation interface of the aggregation group for equipment is not enabled on safe MAC synchronizing function.Phase It answers, after main equipment determines the configuration parameter after negotiating, without sending the configuration parameter carried after negotiating to this for equipment Negotiation response message.

The method of the synchronization MAC Address provided based on the above embodiment, the embodiment of the present application also provides a kind of MAC Address Method without flow aging, this method can be applied to standby equipment.As shown in figure 4, specific step is as follows.

It step 401, is the first MAC Address of no flow aging for aging type, when the sampling for reaching the first MAC Address When the period, the hit condition information of the first MAC Address is detected.

Wherein, whether hit condition information indicates in present flow rate to include the first MAC Address.

It in an implementation, is the first MAC Address of no flow aging type for aging type, standby equipment can be according to no stream The aging type corresponding sampling period is measured, whether include first MAC Address, to obtain first if periodically detecting in present flow rate The hit condition information of MAC Address.If in present flow rate including the first MAC Address, it is determined that the hit shape of the first MAC Address State information is hit condition.If not including the first MAC Address in present flow rate, it is determined that the hit condition of the first MAC Address Information is miss state.

Step 402, first state notification packet is sent to main equipment.

Wherein, the hit condition information of the first MAC Address is carried in first state notification packet.

In an implementation, it after standby equipment obtains the hit condition information of the first MAC Address, can be generated comprising the first MAC The state advertisement message (i.e. first state notification packet) of location and the hit condition information, then, standby equipment can be to main equipment Send first state notification packet.

In a kind of feasible implementation, first state notification packet may include type of message (MSG type) word Section, message length (MSG length) field, safe MAC (secure MAC) field, aggregation group identify (group Identity) field, safe MAC (secure MAC) virtual LAN (English: Virtual Local Area Network, Referred to as: VLAN) identification field, priority (priority) field and safe mac state (secure MAC state) field.Its In, safe mac state field includes miss state, hit condition, addition state and deletes state.In addition, first state is logical Accusing message can also include other fields (such as device identification field etc.), and the embodiment of the present application is not construed as limiting.As shown in Table 2, For a kind of example of state advertisement message provided by the embodiments of the present application.

Table two

Wherein, state is added in safe MAC VLAN identification field, precedence field and safe mac state field and is deleted Except state is synchronous with MAC Address for the update of MAC Address static state, specific process is subsequent to will do it detailed description.

Step 403, the first state response message that main equipment is sent is received.

Wherein, the hit results of the first MAC Address are carried in first state response message.
