Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of method and apparatus of deleting VLAN information.
Background technology
VLAN (Virtual Local Area Network, VLAN) refers on the basis of switched LAN, the crossed over different segment that the Adoption Network management software consists of, the end to end logical network of heterogeneous networks.VLAN can be divided into VLAN based on port by type, based on the VLAN of MAC (Media AccessControl, FDDI sublayer protocol) address, based on the VLAN of agreement, based on the VLAN of subnet and based on the VLAN of comprehensive strategic.Wherein, the advantage that VLAN has comprises: the restriction broadcast domain, broadcast domain is limited in the VLAN, and to save bandwidth, improve network throughput; Strengthen security of local area networks, the two layer message between VLAN is isolated mutually, the user in VLAN can not with other VLAN in user's direct communication; Make up flexibly virtual workgroup, divide different users to different working groups with VLAN.When switch reconfigures or create VLAN, the vlan information of all of the port in the switch and the vlan information of switch need to be removed.
In the prior art, the vlan information of the vlan information of all of the port in the switch and switch is removed the method for (deleting in batches VLAN) as shown in Figure 1, the method may further comprise the steps:
Step S101 obtains each VLAN to be deleted successively.
Step S102 obtains each port (port) among the VLAN successively.
Wherein, this port is the port with above-mentioned vlan information to be deleted that gets access to.
Step S103, mode flush (removing) FDB (ForwardingDatabase according to port and VLAN, forwarding database, be the MAC Address list item that hardware is preserved) the MAC record of middle port, be about to mate simultaneously in the FDB table dynamic MAC address list item deletion of this port and VLAN to be deleted.
Wherein, the MAC Address list item of this hardware preservation is the dynamic MAC address list item in the switch.
Step S104 removes the MAC record of shadow (software preserve MAC Address list item) middle port according to the mode of port and VLAN, is about to mate simultaneously in the shadow table static mac address table entry deletion of this port and VLAN to be deleted.
Wherein, the MAC Address list item of this software preservation is the static mac address list item in the switch.
Step S105 deletes port from VLAN, be about to delete from this port all about the information of VLAN to be deleted in the port.
Step S106, judge among this VLAN all of the port whether all traversal finish, if traversal is finished, all of the port information deletion of this VLAN is finished, and forwards step S107 to, otherwise forwards step S102 to.
Wherein, each VLAN can corresponding a plurality of ports, VLAN (VLAN to be deleted) information of each port all need to be disposed.
Step S107 removes the MAC record of VLAN among the FDB according to the VLAN mode, is about to the dynamic MAC address list item deletion of this VLAN of coupling in the FDB table.
Step S108 removes the MAC record of VLAN among the shadow according to the mode of VLAN, is about to the static mac address table entry deletion of this VLAN of coupling in the shadow table.
Step S109 carries out deletion VLAN, soon deletes from switch all about the information of this VLAN.
Step S110, judge all VLAN to be deleted whether all traversal finish, if traversal is finished, the vlan information of all of the port and the vlan information of switch are all disposed, and finish this flow process, otherwise forward step S101 to, continue to obtain VLAN to be deleted.
Concrete, in a main task, remove the handling process of vlan information, in carrying out deletion FDB table, before the dynamic MAC address list item, need specific semaphore of first to file, when this semaphore is arrived in application, could delete dynamic MAC address list item in the FDB table.Wherein, this specific semaphore is so that current main task of carrying out only has one, the conflict that has caused when having avoided a plurality of tasks to carry out simultaneously.After a main task is finished, must discharge this semaphore, wherein, the process that discharges this semaphore is finished in interrupting Processing tasks.
Carry out to remove in the FDB table after the dynamic MAC address list item in main task, continue the main task handling process, in again carrying out deletion FDB table during the dynamic MAC address list item, also need to apply for specific semaphore, at this moment, when above-mentioned semaphore is interrupted Processing tasks release, can applies for specific semaphore, thereby again delete dynamic MAC address list item in the FDB table; When above-mentioned semaphore also is not interrupted Processing tasks release, main task will be forced to switch away, can't again delete dynamic MAC address list item in the FDB table, be dispatched to the interruption Processing tasks of release semaphore when task dispatch, and when above-mentioned semaphore is discharged, dispatch back the main task application to this specific semaphore, and again delete dynamic MAC address list item in the FDB table.Wherein, each port all needs to carry out the process of dynamic MAC address list item in the above-mentioned deletion FDB table among the VLAN to be deleted, and VLAN to be deleted also needs to carry out the process of dynamic MAC address list item in the above-mentioned deletion FDB table.
Based on top analysis, when the batch deleting VLAN information, there is at present following shortcoming:
When a large amount of vlan information of deletion, repeatedly remove dynamic MAC address list item and the process of removing static mac address list item in the shadow table in the FDB table with carrying out, expended the plenty of time, for example, comprise 52 ports for removing among 4093 VLAN, each VLAN, will carry out dynamic MAC address list item and the process of removing static mac address list item in the shadow table in the inferior removing FDB table of 216929 (52*4093+1*4093), significantly reduce efficient.And, switch owing to carry out continually task between the interruption Processing tasks of main task and release semaphore, have a strong impact on execution efficient, expend the plenty of time.

Step S203 deletes described MAC Address corresponding relation.
Among the present invention, when this deletes described MAC Address corresponding relation, be not limited to and once delete all MAC Address corresponding relations, for the present invention, can carry out secondary, three times or the MAC Address corresponding relation of all VLAN to be deleted in the deletion action deletion switch repeatedly, compare with the MAC Address corresponding relation of only removing of prior art at every turn, only need among the present invention to get final product if it were not for only remove a MAC Address corresponding relation at every turn.
Step S204 deletes the port corresponding with described VLAN to be deleted;
Step S205 deletes described VLAN to be deleted.
Wherein, among the above-mentioned step S203-step S205, the port that deleting MAC address corresponding relation, deletion are corresponding with described VLAN to be deleted and delete between the described VLAN to be deleted not successively ordinal relation can carry out deletion action according to actual needs.
Among the present invention, after getting access to VLAN to be deleted, need the information of this VLAN of deletion, the information of this VLAN comprises: corresponding to the port information of this VLAN, corresponding to the MAC information of this VLAN and corresponding to the identification information of this VLAN, the identification information of this VLAN i.e. this VLAN.
The method of a kind of deleting VLAN information that first embodiment of the invention proposes, the applicable scope of the method includes but not limited to delete the vlan information in the switch, for example, can delete in batches the vlan information that uses in the Ma Weier chip switch by use the method.As shown in Figure 3, the method for this deleting VLAN information may further comprise the steps:
Step S301 obtains each VLAN to be deleted in the switch successively.
In network when using VLAN to carry out data communication, the network equipment utilizes the VLAN under the VLAN ID identification message, wherein, VLAN numbered under VLAN ID represented message, length is 12bit, span is 0～4095,0 and 4095 is the value that keeps in the agreement, and the span of VLAN ID is 1～4094, namely in switch, dispose at most 4094 VLAN, when deletion VLAN, first VLAN (VLAN 1) can not delete, and other VLAN (VLAN 2～VLAN 4093) all can delete, in the present invention, all VLAN in take the VLAN to be deleted that gets access to as switch outside the VLAN 1 describe as example.Wherein, after getting access to a VLAN to be deleted, with the information deletion of this VLAN in the port, and the information of deleting this VLAN, obtain VLAN next to be deleted, carry out the operation of deleting VLAN information and port vlan information.
Step S302 obtains each port with vlan information to be deleted successively.
For example, getting access to a VLAN to be deleted is VLAN 5, when all comprising the information of this VLAN 5 in a plurality of ports, need to in a plurality of ports about the information deletion of VLAN5, namely obtain successively each port in a plurality of ports, after getting access to a port, delete VLAN 5 relevant informations in this port, and obtain the next port in a plurality of ports.Wherein, in switch, VLAN can corresponding a plurality of ports, and a port also can belong to a plurality of VLAN, namely in a port a plurality of vlan informations is arranged.
Step S303 judges in the switch FDB table whether the dynamic MAC address list item that mates simultaneously port and VLAN to be deleted is arranged, and when having mated the dynamic MAC address list item of port and VLAN to be deleted simultaneously, forwards step S304 to, otherwise, forward step S305 to.
Wherein, preserved the dynamic MAC address list item of switch middle port and the dynamic MAC address list item of VLAN in this FDB table, VLAN appropriate ports above-mentioned and to be deleted are the port with vlan information to be deleted that gets access among the step S302.
Step S304 removes the dynamic MAC address list item that mates simultaneously this port and vlan information to be deleted in the FDB table according to the mode of port and VLAN.
Step S305 judges in the switch shadow table whether the static mac address list item that mates simultaneously port and VLAN to be deleted is arranged, and when having mated the static mac address list item of port and VLAN to be deleted simultaneously, forwards step S306 to, otherwise, forward step S307 to.Wherein, the static mac address list item of switch middle port and the static mac address list item of VLAN have been preserved in this shadow table.
Among the present invention, judge the static mac address list item that whether mates simultaneously port and VLAN to be deleted in the switch and judge that the dynamic MAC address list item that whether mates simultaneously port and VLAN to be deleted in the switch does not have ordinal relation successively, namely can carry out the deterministic process among the step S305 before step S303.
Concrete, in switch, all preserved the FDB table, comprise the MAC Address list item in this FDB table, the record of the corresponding MAC Address list item of each bar FDB list item (each in the FDB table), this MAC Address list item comprises: dynamic MAC address list item and static mac address list item.
Wherein, the MAC Address list item in the FDB table generates by following approach or changes.(1) switch self study, switch is according to the source MAC, port, the VLAN ID that receive packet, automatically upgrade the MAC Address list item in the FDB table, be that switch is according to the mac address information that receives from all of the port, generate or safeguard the MAC Address list item, when switch receives frame data, determine it is that this Frame is filtered or transmits according to the MAC Address list item; (2) manual increasing increases the MAC Address list item in the FDB table by hand by command line interface.
Wherein, the number of MAC Address list item can be determined by product in the FDB table, each MAC Address list item in the FDB table is by MAC Address and VLAN ID unique identification, and the content in the FDB table includes but not limited to: MAC Address, the port numbers related with MAC Address, show with title, the FDB of the related VLAN of MAC Address in each sign (Flags); The implication of each sign is specially in this FDB table: Permanent (static address list item), Dynamic (dynamic address list item).
Wherein, the most at first, all MAC Address list items in the switch FDB table all are dynamic, if (ageing time) afterwards through after a while, the corresponding network equipment of this MAC Address list item does not have transfer of data, and this MAC Address list item will be deleted, thereby prevents that the MAC Address list item is too huge, namely when be sure of that certain network equipment is removed from network after, with MAC Address list item deletion from the FDB table of this network equipment.If ageing time is set as 0, this MAC Address list item will be stored in the FDB table and can dynamically do not deleted, and when the switch shutdown or when restarting, all dynamic MAC address list items are all with deleted.
Wherein, the static mac address list item must be configured by program (for example h.link) by the manual setting of system manager or server, a static mac address list item must be a unicast address, and can not have the MAC Address of two static address list items identical.When the MAC Address list item in the FDB table is the static mac address list item, do not allow switch random, change static mac address list item in the FDB table automatically, thereby realized the fixing corresponding of port and MAC Address, the network equipment in this corresponding scope can't not receive from the next packet of switch, and the static mac address list item in namely showing by use FDB has been realized the binding between MAC and the port.
Certainly, dynamic MAC address list item in the switch and static mac address list item only need during the preserving existence intersection property changes planes, might not be kept in the FDB table, for example, by using the hardware in the switch to preserve the dynamic MAC address list item, preserve the static mac address list item by using the software in the switch.Among the present invention, the dynamic MAC address list item is kept in the FDB table, the static mac address list item is kept in the shadow table describes for example.
Step S306, with the information recording/of this port in switch.
Among the present invention, can in the form of switch, record the information of port, for example, by newly-built form StaticMacPortList (static MAC port tabulation), be used for storing the port information with static mac address information of above-mentioned VLAN to be deleted, the information that has VLAN 5 to be deleted in the port 3, and shadow table has been when having mated simultaneously the MAC Address list item (all being static MAC Address list items in the shadow table) of port 3 and VLAN 5, and the information (for example sign) of this port is recorded in the StaticMacPortList table of switch.
Step S307 deletes the information all about VLAN to be deleted in the port from this port.
For example, when containing the information of VLAN 5 to be deleted in the port 3, the information all about VLAN 5 in the port 3 is deleted from port 3.
Step S308, judge have this vlan information all of the port whether all traversal finish, if traversal is finished, all of the port information deletion of this VLAN is finished, and forwards step S309 to, otherwise forwards step S302 to.
Wherein, port with vlan information to be deleted may have a lot of (for example 52), at this moment, need to be with the information deletion of the VLAN to be deleted in each port, when traversal is not finished, need to rotate back into step S302, re-start step S302 to the flow process of step S307, finish until will have the port traversal of vlan information to be deleted.
Step S309 removes the static mac address list item that mates simultaneously this port and VLAN to be deleted in the shadow table according to the port information that records in the switch.
Wherein, the port information that will have the static mac address list item among the step S306 all has been stored in the StaticMacPortList table of switch, in this step, by from the StaticMacPortList table, obtaining the corresponding port of port information of record, remove the static mac address list item that mates simultaneously this port and VLAN to be deleted in the shadow table according to the mode of port and VLAN.
Step S310 judges whether remain the dynamic MAC address list item of deleting VLAN information in the switch FDB table, if so, forwards step S311 to, otherwise, forward step S312 to.Wherein, preserved the dynamic MAC address list item that has vlan information in the switch in this FDB table.
Step S311 removes the dynamic MAC address list item that has vlan information to be deleted in the FDB table according to the mode of VLAN.
Among the present invention, in step S304, removed the dynamic MAC address list item that mates simultaneously port and vlan information to be deleted in the FDB table according to the mode of port and VLAN, and in subsequent step, traveled through all of the port with vlan information to be deleted, judge among the step S310 when whether remaining the dynamic MAC address list item of deleting VLAN information in the FDB table, no longer included the MAC Address of vlan information to be deleted in this switch, just do not needed to carry out this step S311 yet, be step S310 the determination result is NO, directly forward step S312 to.In particular cases, remove when mating simultaneously the dynamic MAC address list item of port and vlan information to be deleted in the FDB table according to the mode of port and VLAN among the step S304, when the MAC Address list item in the deletion FDB table (hardware table item) is more, the deletion of software program and hardware table item can not be finished synchronously, at this moment, judge among the step S310 when whether remaining the dynamic MAC address list item of deleting VLAN information in the FDB table, software program is thought the MAC Address that is still waiting deleting VLAN information in this switch, namely need to carry out this step, remove the dynamic MAC address list item that has vlan information to be deleted in the FDB table according to the mode of VLAN.
Step S312 judges whether remain the static mac address list item of deleting VLAN information in the switch shadow table, if so, forwards step S313 to, otherwise, forward step S314 to.Wherein, preserved the static mac address list item that has vlan information in the switch in this shadow table.
Among the present invention, judge that whether whether remain the static mac address list item and judging of deleting VLAN information in the switch has the not ordinal relation of priority of the dynamic MAC address of VLAN to be deleted list item in the switch, namely can carry out the deterministic process among the step S312 before step S310.
Among the present invention, judge whether remain in the switch FDB table deleting VLAN information the dynamic MAC address list item and judge whether switch shadow remains the implementation of static mac address list item of deleting VLAN information in showing, can also whether the dynamic MAC address list item that mate simultaneously port and VLAN to be deleted be arranged in judging switch FDB table and judge switch shadow operates before whether the static mac address list item that mates simultaneously port and VLAN to be deleted being arranged in showing, when remaining the dynamic MAC address list item of deleting VLAN information in the FDB table, can in switch, record the identification information of VLAN, vlan information according to all VLAN to be deleted in the disposable deletion switch of the identification information FDB table of record VLAN, and/or when remaining the static mac address list item of deleting VLAN information in the shadow table, can in switch, record the identification information of VLAN, according to the vlan information of all VLAN to be deleted in the disposable deletion switch of the identification information shadow table of record VLAN.Namely in remove FDB table according to the mode of port and VLAN, mate simultaneously the dynamic MAC address list item of port and vlan information to be deleted and remove according to the mode of port and VLAN mate simultaneously the static mac address list item of port and vlan information to be deleted in the shadow table before, remove the dynamic MAC address list item of vlan information to be deleted in the FDB table and remove the static mac address list item of vlan information to be deleted in the shadow table according to the mode of VLAN according to the mode of VLAN.
Step S313 removes the static mac address list item that has vlan information to be deleted in the shadow table according to the mode of VLAN.
Among the present invention, removed the static mac address list item that mates simultaneously this port and VLAN to be deleted in the shadow table according to the mode of port and VLAN among the step S309, and during deletion static mac address (software preserve MAC Address), do not relate to the synchronous problem of software and hardware, in step S312, judge when whether remaining the static mac address list item of deleting VLAN information in the switch shadow table, do not had the static mac address list item of vlan information to be deleted in this shadow table, namely do not need to carry out and remove the process that has the static mac address list item of vlan information to be deleted in the shadow table in this step, directly forward step S314 to.
Step S314 deletes the relevant information of all VLAN to be deleted from switch.
Step S315, judge all VLAN to be deleted whether all traversal finish, if traversal is finished, the vlan information of all of the port and the vlan information of switch are all disposed, and finish this flow process, otherwise forward step S301 to, continue to obtain VLAN to be deleted.
Among the present invention, to delete VLAN 2～VLAN 4093 as the example explanation, namely need to obtain successively each VLAN among VLAN 2～VLAN 4093, repeatedly the flow process among execution in step S301～step S314.
Among the present invention, in a main task, remove the handling process of vlan information, in carrying out deletion FDB table before the dynamic MAC address list item, only have when applying for to a specific semaphore, could delete dynamic MAC address list item in the FDB table, in executing deletion FDB table, after the dynamic MAC address list item, in this main task, carry out the process that discharges this semaphore, thereby the task of having avoided applying for the semaphore failure next time and having caused is switched, and main task can not switched away.Namely be put in the main task by the process with release semaphore and carry out, reduce the time that the wait task dispatching office expends, when FDB was removed in the execution of a large amount of number of times, the time of implementation shortened successful.
As seen, among the present invention, when the vlan information of port is removed, by before removing the MAC address list item, carrying out the step of judging, greatly reduced and carried out the number of times of removing the MAC Address list item, by the static mac address list item among the disposable deletion shadow after the searching loop port finishes, only once traveled through and search the shadow table, improve execution efficient, shortened the time of implementation.For example, when the port with vlan information to be deleted is 52, in the prior art, need to carry out and remove the dynamic MAC address list item for 52 times and remove the static mac address list item 52 times, and adopt batch of the present invention to delete the method for VLAN, only need to determine to carry out the number of times of removing FDB according to the dynamic MAC situation on reality VLAN to be deleted and the port (when not mating the dynamic MAC address list item of port and vlan information to be deleted in the FDB table, not needing to carry out reset procedure), and the static mac address list item of removing among the shadow only need be carried out once, so that number of purge greatly reduces, greatly shortened the time of implementation.
When vlan information is removed, removing the step of also judging before the MAC Address list item, no longer need to carry out the process of removing static mac address among the shadow, and greatly reduced the process (even not needing to carry out the process of removing dynamic MAC address in the FDB table) of removing dynamic MAC address in the FDB table of carrying out, significantly reduce the number of times of removing, greatly shortened the time of implementation.
To sum up, the method for the batch deletion VLAN that the application of the invention provides shortens the time of implementation greatly.For example, when switch need to be deleted 4093 VLAN in batches, each VLAN comprises 52 ports, and when not having dynamic MAC address list item and static mac address list item in the switch, carry out the order of 4093 VLAN of deletion according to prior art, need more than 1 hour, and adopt the present invention to carry out the order of 4093 VLAN of deletion, only need about 4 minutes and 30 seconds.
Among the present invention, the main body of carrying out the aforesaid operations process includes but not limited to switch, can control the equipment of this switch, can carry out the aforesaid operations flow process program, can send this software to switch.
