All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The method, the electronic device, and the storage medium for communicating with the server according to the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 illustrates a method for communicating with a server according to an embodiment of the present invention, which may be performed by a switch, and the method includes the following steps:
step 102: and under the condition that the target server does not finish the configuration of the operating system, the port of the switch is correspondingly connected with the port of the target server in a communication mode.
Specifically, the target server is a bare machine when an Operating System (OS) is not loaded and/or the configuration of the OS is not completed, and the target server randomly finds a port to communicate with the switch side if the target server needs to remotely download the OS and configure in the bare machine state. At this time, on the switch side, in order to improve the stability of the network, link aggregation or cross-device link aggregation is generally adopted in networking to interface with the target server, that is, the target server is usually communicated with through a link aggregation mode. At this time, if the target server randomly selects a port to interface with the link aggregation group on the switch side, some problems may occur, such as:
1. if the switch side uses dynamic link aggregation to interface a single port of the target server, communication may not be possible because the target server is a bare machine and no communication protocol related to link control is configured.
2. If the switch side uses static link aggregation to interface a single port of the target server, at this time, if the target server downloads OS and configuration through the switch side network, the switch side link aggregation group needs to send data traffic to other ports, and the target server side cannot provide other ports for receiving data traffic because only one port is provided for interfacing.
Therefore, in the related art, no matter whether the switch side uses a dynamic link aggregation group or a static link aggregation group to interface the bare metal target server, since the target server side interfaces with the link aggregation group of the switch through only one port, there is a problem that communication between the switch and the target server side is abnormal.
In the embodiment of the present application, in order to solve the above problem, when configuring a switch in advance, all ports on the switch for performing communication connection with a target server have been configured as a link aggregation group, the switch may communicate with the target server in a link aggregation group mode through the link aggregation group, and for the link aggregation group of the switch, an automatic break-up attribute is further configured, that is, each member port of the link aggregation group of the switch is allowed to automatically switch between a single-port mode and a link aggregation group mode, where the single-port mode, that is, each member port of the link aggregation group may individually perform communication connection with a port of a corresponding target server.
In a case that it is determined that the target server does not load the operating system and/or does not complete the operating system configuration, the switch may be communicatively connected to the target server in a single-port mode, that is, a port of the switch may be communicatively connected to a port of the target server correspondingly, where the port of the switch may be at least one port of a plurality of ports of a switch link aggregation group, and the port of the switch and the port of the target server are in a one-to-one correspondence at this time.
As an example, for example, in a case where the target server does not load the operating system and/or does not complete the operating system configuration, the switch may be communicatively connected to the switch through the port P, and in a case where it is determined that the target server does not load the operating system and/or does not complete the operating system configuration, the switch may be communicatively connected to the port P of the target server through the port M, and it should be noted that the port M of the switch and the port P of the target server have a one-to-one correspondence relationship.
In the embodiment of the application, under the condition that the configuration of the operating system is not completed by the target server, the port of the switch corresponds to the port of the target server in communication connection, wherein the port of the switch is at least one port of a plurality of ports of a link aggregation group of the switch, and the port of the switch corresponds to the port of the target server one to one.
In one implementation, it is determined that the target server does not complete an operating system configuration in a target case, wherein the target case comprises: the condition that all ports in the link aggregation group of the switch do not receive the target protocol message sent by the target server; or a condition where all ports in a link aggregation group of the switch are down. The incomplete operating system configuration comprises: no operating system is loaded; or the operating system has been loaded but the configuration of the operating system has not been completed.
Specifically, if the target server finishes loading the operating system and finishes configuration of the operating system, a target Protocol packet may be sent to the switch, where the target Protocol packet may be a Link Aggregation Control Protocol (LACP) packet, and therefore, if all ports in a Link Aggregation group of the switch do not receive the target Protocol packet sent by the target server, it is indicated that the target server does not load the operating system and/or does not finish configuration of the operating system, and at this time, the ports in the Link Aggregation group of the switch need to be in communication connection with the ports of the target server through a single-port mode.
When all ports in the link aggregation group of the switch are in communication connection with the target server, if all ports in the link aggregation group of the switch are down, the target server may have unexpected situations such as restart, and at this time, the ports in the link aggregation group of the switch also need to be converted into a single-port mode.
Thus, by determining that the target server does not load the operating system and/or does not complete the operating system configuration in a target situation, wherein the target situation comprises: the condition that all ports in the link aggregation group of the switch do not receive the target protocol message sent by the target server; or when all ports in the link aggregation group of the switch are down, whether the operating system is loaded by the target server or not and whether the operating system configuration is completed or not can be determined, and further whether the switch is in communication connection with the target server through a single-port mode or not can be determined.
In one implementation, after the corresponding communication connection with the port of the target server through the port of the switch, the method further includes:
and under the condition that the target server loads an operating system and completes the configuration of the operating system, the link aggregation group of the switch is in communication connection with the link aggregation group of the target server.
Specifically, if the port of the switch receives a target protocol packet sent by the target server, it may be determined that the target server loads the operating system and completes configuration of the operating system, and the port of the switch may be in communication connection with the target server through a link aggregation mode, that is, a link aggregation group of the switch is in communication connection with a link aggregation group of the target server.
Therefore, under the condition that the target server loads the operating system and completes the configuration of the operating system, the link aggregation group of the switch is in communication connection with the link aggregation group of the target server, so that the communication effect of the link aggregation group of the switch is realized, the butt joint accuracy of the switch and the target server is improved, the oscillation and abnormity in the communication process of the switch and the target server are avoided, and the stability and the fault tolerance of a communication network of the switch and the target server are improved.
In one implementation, communicatively connecting, through the link aggregation group of the switch, with the link aggregation group of the target server includes:
acquiring a negotiation result of the link aggregation group of the switch and the link aggregation group of the target server; and under the condition that the negotiation result indicates that the negotiation of at least one port in the link aggregation group of the switch is successful, the link aggregation group of the switch is connected with the link aggregation group of the target server in a communication mode.
Specifically, after the switch receives a target protocol packet sent by the target server, the link aggregation group of the switch needs to enter a negotiation state to perform bidirectional negotiation with the link aggregation group of the target server, where the bidirectional negotiation is to determine which ports are active ports in the link aggregation group of the switch, that is, ports capable of performing communication connection normally, so that if a negotiation result of the link aggregation group of the switch and the link aggregation group of the target server is that at least one port has successfully negotiated, all ports of the switch enter a link aggregation group mode, and the link aggregation group of the switch can be in communication connection with the link aggregation group of the target server.
Thus, the negotiation result of the link aggregation group of the switch and the link aggregation group of the target server is obtained; under the condition that the negotiation result indicates that the negotiation of at least one port in the link aggregation group of the switch is successful, the link aggregation group of the switch is in communication connection with the link aggregation group of the target server through the link aggregation group of the switch, and under the condition that the negotiation of at least one port in the link aggregation group of the switch is successful, the link aggregation group of the switch is only in communication connection with the link aggregation group of the target server, so that the correctness of the communication connection between the switch and the target server is ensured, the oscillation and the abnormity in the communication process between the switch and the target server are avoided, and the stability and the fault tolerance of a communication network between the switch and the target server are improved.
In one implementation, after obtaining a negotiation result of the link aggregation group of the switch and the link aggregation group of the target server, the method further includes:
and under the condition that the negotiation result indicates that at least one port in the link aggregation group of the switch fails to negotiate, receiving a target protocol message sent by the target server through a port in a blocking state in the link aggregation group of the switch, wherein the port in the blocking state is the port in the link aggregation group of the switch which fails to negotiate.
Specifically, when the negotiation result of the link aggregation group of the switch and the link aggregation group of the target server includes that at least one port fails in negotiation, that is, the port that fails in negotiation is in an inactive (inactive) state, the port that does not active may be set in a spanning tree blocking (block) state, that is, the port that fails in negotiation is set in a blocking state according to a state machine of a spanning tree protocol, and through the port in the blocking state, only the target protocol packet sent by the target server may be received, and the port in the blocking state does not forward data traffic and does not participate in communication connection any more.
Therefore, under the condition that the negotiation result indicates that at least one port in the link aggregation group of the switch fails to negotiate, the port in the blocking state in the link aggregation group of the switch receives the target protocol message sent by the target server, wherein the port in the blocking state is the port in the link aggregation group of the switch which fails to negotiate, the port in the blocking state can be determined, and the port in the blocking state only receives the target protocol message, so that the correctness of the communication connection between the switch and the target server is ensured, the oscillation and the abnormity in the communication process between the switch and the target server are avoided, and the stability and the fault tolerance of the communication network between the switch and the target server are improved.
In one implementation, the negotiating at least one port in the link aggregation group of the switch is successful, including:
under the condition that the communication between a first port in the link aggregation group of the switch and a port in the link aggregation group of the target server is successful, determining that the negotiation of the first port is successful; at least one port in a link aggregation group of the switch fails negotiation, including: and determining that the negotiation of the second port fails when the communication between the second port in the link aggregation group of the switch and the port in the link aggregation group of the target server fails.
Specifically, the purpose of negotiating the port of the link aggregation group of the switch with the port of the link aggregation group of the target server is to determine which ports in the link aggregation group of the switch can be in normal communication connection, and therefore, when negotiating the link aggregation group of the switch with the link aggregation group of the target server, if a first port in the link aggregation group of the switch is in successful communication with a port in the link aggregation group of the target server, it may be determined that the first port is in successful negotiation, where the first port may be one port or multiple ports in the link aggregation group of the switch, and the first port in the link aggregation group of the switch is not limited herein.
Similarly, when the link aggregation group of the switch negotiates with the link aggregation group of the target server, if a second port in the link aggregation group of the switch fails to communicate with a port in the link aggregation group of the target server, it may be determined that the negotiation of the second port fails, where the second port may be one port or multiple ports in the link aggregation group of the switch, and the second port of the link aggregation group of the switch is not limited here.
In this way, under the condition that the communication between the first port in the link aggregation group of the switch and the port in the link aggregation group of the target server is successful, the first port is determined to be successfully negotiated; at least one port in a link aggregation group of a switch fails negotiation, comprising: and under the condition that the second port in the link aggregation group of the switch fails to communicate with the port in the link aggregation group of the target server, determining that the negotiation of the second port fails, and determining the port with successful negotiation and the port with failed negotiation in the link aggregation group of the switch.
In one implementation, the method further comprises:
and under the condition that the negotiation of the port in the blocking state is successful, forwarding data traffic through the port in the blocking state which is successfully negotiated.
Specifically, if the subsequent negotiation between the port in the blocking state and the port in the link aggregation group of the target server is successful, which indicates that the port in the blocking state subsequently recovers to the active state, the port in the blocking state may be set to a spanning tree forwarding (forward) state, and the port may normally forward the data traffic.
Therefore, under the condition that the negotiation of the port in the blocking state is successful, the data flow is forwarded through the port in the blocking state which is successfully negotiated, so that the blocking port which recovers the active state can participate in the communication of the target server, the stability of the communication with the target server is improved, and the utilization efficiency of the port of the switch is improved.
In one implementation, the method further comprises:
and deleting the control information corresponding to the target server, which is acquired by the switch, before the communication connection between the switch and the target server is converted.
Specifically, no matter the switch is in communication connection with the target server in the single port mode or the link aggregation group mode, the switch acquires Control information corresponding to the target server as forwarding information of the switch, such as a Media Access Control Address (MAC) of the target server, address Resolution Protocol (ARP) information, routing information, and the like.
In this embodiment, before the switch is switched in communication connection with the target server, control information corresponding to the target server acquired by the switch before the communication connection is switched may be deleted, for example, if the communication connection between the switch and the target server needs to be switched from a single-port mode to a link aggregation group mode, before the switching, the control information of the target server acquired by the switch in the single-port mode needs to be deleted, and if the communication connection between the switch and the target server needs to be switched from the link aggregation group mode to the single-port mode, before the switching, the control information of the target server acquired by the switch in the link aggregation group mode needs to be deleted.
Therefore, before the communication connection between the switch and the target server is converted, the control information corresponding to the target server acquired by the switch is deleted, and the problem that the control information of the target server acquired in different communication modes is inconsistent and is abnormal is solved.
To illustrate the present application in further detail, the present application provides the following examples:
example one:
configuring ports A1 and A2 at the exchange side as a link aggregation group A, configuring the link aggregation group with a break-up attribute, and butting the ports B1 and B2 of a target server, wherein the MAC address of the server is 00: 22, and the IP address is 10.0.0.1.
(1) The target server is initially in a state without any OS and configuration, and communicates with the switch using B1 by default.
(2) Ports A1 and A2 of the switch are configured as a link aggregation group a and have a break-up attribute, and the switch side listens to the LACP message at the ports A1 and A2.
(3) And if the port of the switch does not intercept the LACP message, the A1 and A2 ports of the switch are in a single-port mode, the configuration information of the A1 and A2 ports is obtained, and the configuration information is written into a port configuration register of the switch.
(4) The switch is connected with the B1 port of the target server through the A1 port in communication, and learns that the MAC address 00 of the target server.
Example two:
configuring ports A1 and A2 at the exchange side as a link aggregation group A, configuring the link aggregation group with a break-up attribute, and butting the ports B1 and B2 of a target server, wherein the MAC address of the server is 00: 22, and the IP address is 10.0.0.1.
(1) The target server completes the loading of the OS and configuration, discovers that B1 and B2 are link aggregation groups, and therefore the server starts LACP negotiation with the switch.
(2) Any one of the ports A1 and A2 of the switch receives the LACP message, namely the port is intercepted and found, and the ports A1 and A2 enter an LACP negotiation state.
(3) If both A1 and A2 negotiate successfully, A1 and A2 enter a link aggregation group mode, perform communication connection with a link aggregation group composed of servers B1 and B2, delete the entries of ARP, MAC, route, and the like learned by original A1 or A2, learn the entry of ARP, MAC, and the like again through the link aggregation group a formed by A1 and A2, and learn that the MAC address 00 of the target server is.
(4) If only A1 in A1 and A2 is successfully negotiated, A2 enters a spanning tree block state, and if neither A1 nor A2 is successfully negotiated, A1 and A2 all enter the spanning tree block state.
Example three:
the ports A1 and A2 configured on the exchange side are a link aggregation group A and are configured to have a scatter attribute, and the ports B1 and B2 of the target server are butted.
After the negotiation of the ports A1 and/or A2 is successful, if the target server is restarted, all the ports in the link aggregation group of the switch will be down, at this time, the ports A1 and A2 of the switch are switched from the link aggregation group mode to the single-port mode, the entries of ARP, MAC, route and the like learned by the link aggregation group a of the switch are deleted, and the ports A1 or A2 of the switch and the randomly selected ports B1 or B2 of the target server prepare for single-port communication.
Fig. 2 is a schematic diagram illustrating a communication connection between a switch and a target server according to an embodiment of the present application, where as shown in fig. 2, when a port of a switch 210 is connected to a port of a target server 220, if the target server 220 does not load an operating system and/or does not complete an operating system configuration, the target server 220 directly selects a port to perform communication connection with the switch 210, and on the switch 210 side, under a condition that it is determined that the target server 220 does not load an operating system and/or does not complete an operating system configuration, a port is also selected to perform communication connection with the port selected by the target server 220, as shown in fig. 2, the target server 220 may select a port B1, and the switch 210 may select a port A1 to perform communication connection with a port B1 of the target server 220.
If the target server 220 loads the operating system and completes the configuration of the operating system, the A1 port and the A2 port of the switch 210 may enter a link aggregation group mode to negotiate with the port of the target server 220, and if the negotiation is successful, the link aggregation group of the switch 210 may be in communication connection with a link aggregation group formed by the B1 port and the B2 port of the target server 220.
Fig. 3 is a schematic diagram illustrating a switching of a communication mode of a switch according to an embodiment of the present application. As shown in fig. 3, in a case that it is determined that the target server does not load the operating system and/or does not complete the operating system configuration, the switch may be communicatively connected to the target server through a single-port mode, that is, a port of the switch may be communicatively connected to a port of the target server correspondingly, where the port of the switch may be at least one port of a plurality of ports of a switch link aggregation group, and the port of the switch and the port of the target server correspond to each other one to one at this time.
If a port of the switch receives a target protocol message (LACP message) sent by a target server, it may be determined that the target server loads an operating system and completes configuration of the operating system, the port of the switch may be converted into a link aggregation group mode, after the switch receives the target protocol message sent by the target server, a link aggregation group of the switch needs to enter a negotiation state to perform bidirectional negotiation with the link aggregation group of the target server, where the negotiation may be LACP negotiation, and the purpose of the bidirectional negotiation is to determine which ports are ports in an active state in the link aggregation group of the switch, that is, ports that can perform communication connection normally, and set a port that fails in negotiation as a blocking state, and if a negotiation result of the link aggregation group of the switch and the link aggregation group of the target server is that at least one port has successfully negotiated, all ports of the switch enter the link aggregation group mode, and the link aggregation group of the switch may be in communication connection with the link aggregation group of the target server.
Before the communication connection between the switch and the target server end is converted into the link aggregation mode from the single-port mode, the entries of the MAC, ARP, routing and the like of the target server, which are learned by the switch through the single-port mode, need to be deleted, when the target server is restarted, the port of the switch will be down, at this time, the passing mode of the switch needs to be converted into the single-port mode from the link aggregation group mode, and the entries of the MAC, ARP, routing and the like of the target server, which are learned by the switch through the link aggregation group mode, also need to be cleared before the conversion.
In the above process, the configuration information of the port of the switch and the configuration information of the LACP message of the target server do not interfere with each other, and respective effective effects can be presented, and in implementation, two sets of configuration information can be used to take effect at different levels, and configuration information conflicting with each other in two sets of configurations, such as Virtual Local Area Network (VLAN), can be used to perform coverage switching according to an effective mode.
In the method for communicating with the server provided by the embodiment of the present application, the executing body may be a device for communicating with the server, or a control module in the device for communicating with the server for executing the method for communicating with the server. In the embodiment of the present application, a method for a device communicating with a server to perform communication with the server is taken as an example, and the device communicating with the server provided in the embodiment of the present application is described.
Fig. 4 is a schematic structural diagram of a device communicating with a server according to an embodiment of the present invention. As shown in fig. 4, the apparatus 400 for communicating with a server includes: a communication module 410.
The communication module 410 is configured to, when a target server does not load an operating system and/or does not complete configuration of the operating system, correspondingly connect, through a port of a switch, a port of the switch to a port of the target server in a communication manner, where the port of the switch is at least one port of a plurality of ports of a link aggregation group of the switch, and the ports of the switch correspond to the ports of the target server one to one.
