Detailed Description
The embodiment of the specification provides a management method, a device, equipment and a medium of a dynamic host configuration protocol server.
When a link aggregation (mlag) is used as a gateway and provides address allocation service, in order to realize redundant backup of the DHCP Server, the functions of the DHCP Server are started on the mlag master and slave equipment, and the same address pool is configured. In this case, DHCP request messages sent by different clients connected in parallel are shared by loads to the mlag master device or the slave device, and DHCP servers of the mlag master device and the slave device are independent of each other, so that address collision occurs. Current schemes for avoiding collisions:
before allocating address, DHCP Server sends icmp5 request with the address to be allocated as destination address, if reply is received, it indicates that there is address conflict, DHCP Server reallocates address pool again
Prior to allocation, an icmp request needs to be issued to confirm whether there is an address conflict.
2. And performing the synchronization of the DHCP table entries between the mlag main and standby equipment, so that the DHCP table entries of the mlag main and standby equipment are kept consistent, and conflicts are avoided when addresses are allocated.
For scheme 1 above: if the more addresses in the pool of assigned addresses of the mlag master or slave are compared to 0, the more collisions are likely and the more times there are a large number of icmp packets in the network to detect collisions,
and the longer the latency required for successful address assignment, the worse the user experience may be.
For 2 above: the DHCP table entries are synchronized between the mlag master and slave devices, certain bandwidth needs to be consumed, the master and slave devices need to maintain the DHCP table entries, and certain consumption is caused for the device performance.
In view of the above-mentioned drawbacks, an object of the embodiments of the present disclosure is to assign a role of 5 primary and secondary to multiple DHCP servers, and only the primary DHCP server responds to the DHCP request, and after the secondary DHCP server receives the DHCP request, the secondary DHCP server directly forwards the DHCP request to the primary device through the peerlink link, so that the primary device provides address allocation service. When the main equipment fails, the DHCP server of the standby equipment directly replies with a DHCP request to provide address allocation service, so that address conflict is avoided.
In order to make the technical solution in the present specification better understood by those skilled in the art, the technical solution in the embodiments of the present specification will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present specification, and it is apparent that the described embodiments are only some embodiments of the present specification, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present disclosure.
Fig. 1 is a schematic flow diagram of a method for 5 management of a dynamic host configuration protocol server according to one or more embodiments of the present disclosure, where the flow may be executed by a management system of the dynamic host configuration protocol server. Some input parameters or intermediate results in the flow allow for manual intervention adjustments to help improve accuracy.
The management system of the dynamic host configuration protocol server of the embodiments of the present specification may include a plurality of dynamic host configuration protocol server modules, and a link aggregation module to which each dynamic host configuration protocol server module is connected
The method flow steps of the embodiment of the present specification are as follows:
s102, acquiring link aggregation master-slave role information in the link aggregation module connected with each dynamic host configuration protocol server module.
In the embodiment of the present disclosure, the link aggregation primary and standby information may perform primary and standby device election according to link aggregation, and determine primary roles and standby roles in a plurality of link aggregation modules in the link aggregation.
S104, marking the master and slave roles by the dynamic host configuration protocol server modules according to the link aggregation master and slave role information.
In this embodiment of the present disclosure, the active/standby roles are marked on the connected dynamic host configuration protocol server according to the link aggregation active/standby role information, for example, the link aggregation module 1 is connected to the dynamic host configuration protocol server module 1, the link aggregation module 2 is connected to the dynamic host configuration protocol server module 2, when the link aggregation module 1 is the active role, the link aggregation module 2 is the standby role, the dynamic host configuration protocol server module 1 is marked as the active role, and the dynamic host configuration protocol server module 2 is marked as the standby role.
And S106, when the first dynamic host configuration protocol server module marked as the master role receives the first request message, responding to the first request message through the first dynamic host configuration protocol server module.
S108, when the second dynamic host configuration protocol server module marked as the standby role receives the second request message, the second request message is forwarded to the first dynamic host configuration protocol server module so as to respond to the second request message through the first dynamic host configuration protocol server module.
Further, when the link aggregation master-slave role information changes, determining the changed link aggregation master-slave role information; and updating the master and slave roles of the plurality of dynamic host configuration protocol server modules according to the changed link aggregation master and slave role information.
For example, the link aggregation module 1 is connected to the dynamic host configuration protocol server module 1, the link aggregation module 2 is connected to the dynamic host configuration protocol server module 2, when the link aggregation module 1 is in a master role and the link aggregation module 2 is in a standby role, the dynamic host configuration protocol server module 1 is marked as a master role, and when the link aggregation module 2 is exchanged as a master role, the dynamic host configuration protocol server module 2 is exchanged as a master role.
Further, when the main character link aggregation module fails, determining a new main character link aggregation module in the rest link aggregation modules; and marking the dynamic host configuration protocol server module connected with the new main role link aggregation module as a main role.
For example, the link aggregation module 1 is connected to the dynamic host configuration protocol server module 1, the link aggregation module 2 is connected to the dynamic host configuration protocol server module 2, and when the link aggregation module 1 is in the master role and the link aggregation module 2 is in the standby role, the dynamic host configuration protocol server module 1 is marked as the master role, and the dynamic host configuration protocol server module 2 is marked as the standby role. When the link aggregation module 1 fails, the link aggregation module 2 is determined to be the primary role, and the dynamic host configuration protocol server module 2 is exchanged to be the standby role.
Further, before marking the active/standby roles by the plurality of dynamic host configuration protocol server modules according to the link aggregation active/standby role information, when the plurality of dynamic host configuration protocol server modules cannot acquire the link aggregation active/standby role information, the active/standby roles of the plurality of dynamic host configuration protocol server modules cannot be determined through the link aggregation active/standby role information, and the plurality of dynamic host configuration protocol server modules can be marked as the active roles, so that a subsequently received request message can be processed.
Further, when the plurality of dynamic host configuration protocol server modules cannot acquire the link aggregation master-slave role information within a preset time, the plurality of dynamic host configuration protocol server modules are marked as master roles, wherein the preset time can be counted through a timer.
In this embodiment of the present disclosure, when responding to the first request packet, the address allocation may be completed by responding to the first request packet with a request and an ACK. Wherein ACK (Acknowledge character) is an acknowledgement character, a transmission class control character that the receiving station sends to the sending station in data communication. Indicating that the transmitted data has been acknowledged with no errors. In the TCP/IP protocol, if the receiver successfully receives data, an ACK data is replied.
Application scenario topology of the embodiments of the present disclosure see fig. 2:
device1 and Device2 turn on mlag and DHCP server to provide address allocation services to downstream devices. Device1 and Device2 have the same address pool and are backup to each other. After receiving the DHCP request of the downlink client, the Switch randomly forwards the DHCP request to the Device1 or the Device2 through link aggregation load sharing, and because the DHCP server of the Device1 and the DHCP server of the Device2 are independent, the Device1 and the Device2 respectively perform address allocation, thereby causing address collision.
The embodiment of the specification provides a DHCP Server master-slave management system based on mrag, which manages the DHCP Server master-slave by means of the mrag master-slave role, avoids conflict of address allocation and improves user experience. See FIG. 3 for a schematic diagram of the device internal modules of the mlag and DHCP Server.
The DHCP Server module obtains the information of the master and slave roles of the mlag from the mlag module, and marks the master and slave roles of the DHCP Server of the device according to the obtained information.
When the DHCP Server marked as the main receives the request message of the client, the DHCP Server can normally respond to the offer and the ACK to complete the address allocation action.
When the DHCP Server marked as the standby automatically sends 1 acl on the mlag port for starting the DHCP Server function, the received client request message is directly forwarded to the DHCP Server marked as the main through the peer link, and the address allocation is carried out by the main DHCP Server, so that the performance consumption of the standby equipment is reduced.
When the DHCP Server module is started, a request is sent to the mlag module at regular time to acquire mlag master-slave role information, a timeout timer is started, no response of the mlag module is received after the timeout time is exceeded, the DHCP Server role of the equipment is set as a master, and acl for forwarding the DHCP request is deleted. If the response of the mlag module is received within the timeout period, the timer is refreshed.
When the primary and standby roles of the mlag change, the primary mlag master device fails, and the primary mlag master device is taken as the DHCP Server master device, which is obviously unsuitable. At the moment, after the master-slave switching occurs to the mlag module, the synchronous switching message can be actively sent to the DHCP Server module, so that the synchronous switching of the master-slave roles of the DHCP Server is realized, the master-slave switching is avoided after the DHCP Server module waits for overtime, and the response speed is improved.
The related parameters of the timer can be set according to the actual network condition to help the equipment to more reasonably manage the master role and the slave role of the DHCP Server. Timer parameters include, but are not limited to: and the DHCP Server can not acquire the overtime time and the overtime times of the mrag master/slave information at the time interval of the timing inquiry of the DHCP Server, the switching delay of the DHCP Server master/slave switching, and the like.
It should be noted that, in the embodiment of the present disclosure, management of multiple DHCP Server master/slave roles is implemented by using an mlag master/slave role, so as to solve the problem of providing address allocation service conflict when multiple DHCP servers exist in the network. Meanwhile, by canceling the response of the standby DHCP Server to the client and maintaining the DHCP table entry, the performance consumption of the standby DHCP Server is reduced.
