An embodiment of the present application provides a method for configuring a network device, which specifically includes the following steps, as shown in fig. 1:
s101, the operation and maintenance terminal sends a connection request for establishing a secure communication protocol to the network equipment.
It should be noted that the Secure communication protocol may be, but is not limited to, Secure Shell (SSH) protocol, and the like, and is not limited herein.
S102, the network equipment receives a connection request for establishing a secure communication protocol sent by the operation and maintenance terminal.
S103, the network equipment feeds back the first result information to the operation and maintenance terminal.
Wherein the first result information indicates whether the connection request to establish the secure communication protocol is granted.
S104, the operation and maintenance terminal receives first result information fed back by the network equipment.
And S105, if the first result information indicates that the network equipment agrees to establish the connection request of the secure communication protocol, the operation and maintenance terminal establishes the secure communication protocol connection with the network equipment.
S106, the operation and maintenance terminal sends a session creation request to the network equipment.
Wherein the session comprises a network configuration protocol. The Network Configuration Protocol is The Network Configuration Protocol, NetConf.
It can be understood that the configuration of the network devices determines whether the requirement for automated deployment of the network devices during the construction and maintenance of the data center can be met, and the conventional CLI configuration is not suitable for meeting such requirement due to the problems described above. Different from the traditional CLI configuration mode, NetConf does not depend on a command line for configuring the network device, and NetConf provides a complete set of mechanism for managing the network device, and a user can add, modify and delete the configuration of the network device through the complete set of mechanism to acquire the configuration and state information of the network device. NetConf is a network configuration and management protocol based on Extensible Markup Language (XML), and uses a simple RPC-based mechanism to implement communication between a client, which may be a script or an application program, and a server, which is a network device.
The NetConf protocol provides a method for directly configuring network equipment by an operation and maintenance terminal, the protocol is internally divided into four layers, namely a safety transmission layer, a message layer, an operation layer and a content layer from bottom to top, the operation and maintenance terminal establishes connection and session with the network equipment by using the safety transmission layer and the message layer, the operation layer and the content layer are mainly used for the configuration process of the network equipment, and the four-layer relation of the NetConf protocol is shown in fig. 2.
The safety transport layer is responsible for establishing communication between the operation and maintenance terminal and the network device through a communication protocol, and the safety advantage of NetConf is also shown here. The communication protocol within the secure transport layer must meet the requirements of being securely encryptable (SSH is commonly used); the message layer is used for enabling the operation and maintenance terminal and the network equipment to mutually send a < hello > message to create a NetConf session (the < hello > message comprises a capability set supported by the operation and maintenance terminal and a NetConf version number), and to transmit an RPC request and a response of the RPC request between the operation and maintenance terminal and the network equipment, wherein the RPC request comprises configuration information in an operation layer and a content layer.
S107, the network equipment receives a session creation request sent by the operation and maintenance terminal.
And S108, the network equipment feeds back second result information to the operation and maintenance terminal.
Wherein the second result information indicates whether the network device approves the creation request of the session.
And S109, the operation and maintenance terminal receives second result information fed back by the network equipment.
And S110, if the second result information indicates that the network equipment agrees to the session creation request, the operation and maintenance terminal and the network equipment create a session.
And S111, the operation and maintenance terminal sends a remote program calling request to the network equipment through the session.
Wherein, the Remote Procedure Call request is Remote Procedure Call, i.e. RPC. The remote program calling request comprises information about operation to be carried out and required data information of the remote program calling.
And S112, the network equipment receives the remote program calling request sent by the operation and maintenance terminal.
S113, the network equipment feeds back an execution result aiming at the remote program calling request to the operation and maintenance terminal through the conversation.
S114, the operation and maintenance terminal receives the execution result of the network equipment for the remote program calling request through the session.
Optionally, in another embodiment of the present application, after all the remote procedure call requests are completed, the session needs to be closed, and therefore, an implementation manner after step S114 is executed further includes:
and the operation and maintenance terminal sends a closing request of the session to the network equipment.
The closing request of the session is used for requesting to close the session between the network equipment and the session closing request.
And the network equipment receives a closing request of the session sent by the operation and maintenance terminal.
And the network equipment feeds back the third result information to the operation and maintenance terminal.
Wherein the third result information indicates whether the network device agrees with the request for closing the session.
And the operation and maintenance terminal receives the third result information fed back by the network equipment.
And if the third result information indicates that the network equipment agrees to the session closing request, the operation and maintenance terminal closes the session.
It can be understood that, in the implementation process of the present application, at any time, the operation and maintenance terminal may initiate an end command to the network device if a special condition is met. Wherein the end command is for ending the session with the network device.
It should be noted that, NetConf access and configuration equipment requires direct connection between an operation and maintenance terminal and network equipment, and although security is guaranteed by an encrypted communication protocol, auditability cannot be guaranteed. In daily operation and maintenance work of a data center, safety audit is an important measure for guaranteeing the safety of an information system. Therefore, the SOM safety operation and maintenance management system is introduced to increase the auditing function of the scheme, and the configuration information and the instruction sent to the network equipment by the SOM transfer operation and maintenance terminal are transmitted. Firstly, logging in the SOM through the operation and maintenance terminal, acquiring a token provided by the SOM, adding the RPC message of NetConf sent by the operation and maintenance terminal into the token, and then forwarding the RPC message to the network equipment by the SOM.
Specifically, as shown in fig. 3, a flowchart for accessing and configuring a network device after adding an SOM is provided:
namely, the operation and maintenance terminal realizes NetConf conversation with the network equipment by calling an interface of the SOM, then sends the RPC request to the SOM and forwards the RPC request to the network equipment through the SOM, records all operations of the operation and maintenance terminal through an auditing function of the SOM, and makes up the defect that the NetConf protocol configuration network equipment lacks the auditing function by using the SOM.
According to the above scheme, the present application provides a method for configuring a network device, comprising: after a safe communication protocol is established with network equipment through an operation and maintenance terminal, a session containing a network configuration protocol is established with the network equipment, a remote program calling request is sent to the network equipment through the session containing the network configuration protocol, and an execution result of the network equipment for the remote program calling request is received; the remote program calling request comprises operation information to be carried out and required data information of the remote program calling. Because the network device is configured through the network configuration protocol without depending on a command line, and the network configuration protocol provides a whole set of mechanism for managing the network device, a user can add, modify and delete the configuration of the network device through the set of mechanism to acquire the configuration and state information of the network device. Therefore, the purpose of large-scale automatic deployment of the network equipment can be achieved.
