Embodiments of the invention

The embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

Embodiment 1

According to an aspect of the embodiments of the present invention, an automatic switching method for an external network port connection type is provided, which is applied to a first subrack management board. The method first monitors a first external network port in a connected state; Whether the first external network port acquires the second pair within a preset time period The device type notification packet sent by the external network port; and finally, when the first external network port obtains the device type notification message sent by the second external network port in the preset time period, according to the device type The notification packet modifies the connection type of the first external network port.

Therefore, the automatic switching method of the external network port connection type in the embodiment of the present invention can automatically identify whether the external network port is connected to the network management server or other subrack management board, and automatically set parameters of the network port to satisfy the network port. The required features of connecting to the network management server or connecting to other subrack management boards avoid the cumbersome manual change of the connection type and resetting the attributes in the related art.

As shown in Figure 2, the method includes:

Step S21: Monitor the first external network port in the connected state.

Any device subrack includes a subrack management board, and the device subrack connection network tube and the device subrack are connected to other device subracks through the external network port on the subrack management board, as shown in FIG. . However, the connection relationship between the multiple external network ports on the subrack management board and the external needs to be changed as necessary. For example, the subrack management board of the second device subrack connected to the third device subrack is connected as shown in FIG. The external network port may need to be disconnected to make it idle. In addition, the external network port in the idle state cannot send and receive packets. Therefore, it is necessary for the method in the embodiment of the present invention to monitor the network ports in the connected state in real time, that is, which network ports can receive and receive packets in time to prepare for subsequent processing.

Step S23: Determine whether the first external network port obtains the device type notification message sent by the second external network port in the preset time period. Optionally, the second external network port is a network port where the external device is in a connected state;

The method for automatically switching the connection mode of the external network port in the embodiment of the present invention sends a device type notification message to the first external network port of the first subrack management board in the connected state by the second external network port in which the external device is connected. Inform the device type of the external device of the first subrack management board.

Step S25: When the first external network port obtains the device type notification message sent by the second external network port in the preset time period, modify the first external network according to the device type notification message. The type of connection for the port. Optionally, in the method for automatically switching the connection mode of the external network port in the embodiment of the present invention, determining whether the second external network port in which the external device is in the connected state is obtained is obtained. The device type notification packet is sent to change the connection type of the first external network port. That is, if the device type notification packet carries the subrack management board information, the connection type of the first external network port is modified to be connected when the external device is determined to be the second subrack management board. If the external device is the network management server, the connection type of the first external network port is changed to the connection network management server type.

Of course, in the embodiment of the present invention, the basis for changing the connection type is not limited thereto. The network management server can also send the device type notification packet to notify the subrack management board that the peer end is connected to the network management server, thereby changing the connection type of the corresponding external network port to the connection network management server type. That is, the subrack management board and the network management server both send the device type notification message, and when the first external network port in the connected state of the subrack management board receives the device type notification message carrying the subrack management board information, The connection type of the first external network port is changed to the connection subrack type; when the first external network port in which the subrack management board is in the connection state receives the device type notification message carrying the network management server information, the The connection type of the external network port is changed to the network management server type.

Optionally, step S23 includes:

Determining, in sequence, whether the packet header of the plurality of packets received by the first external network port is a preset packet header; selecting the packet whose header is the preset packet header, and determining the packet Whether the type field of the packet of the preset header is the preset content; when the type field is the preset content, it is determined that the device type sent by the second external network port to which the external device is connected is obtained. Notification message.

Optionally, any external network port that is in the connected state receives not only the device type notification packet but also some other service packets in the process of receiving the packet. However, the method for automatically switching the connection type of the external network port in the embodiment of the present invention requires only the device type notification message. Therefore, it is necessary to filter the device type notification message from a plurality of messages. Optionally, the device type message has a specific message header and specific content, for example, its message frame can be as shown in the following table:

Table 1 Device Type Notification Message Frame Format

For example, the packet received from the external network interface first identifies the BPDU header and then determines the typeid field of the packet. If the typeid field of the packet is 0x4E435031, the packet is a device type notification packet.

Optionally, modifying the connection type of the first external network port to connect to the network management server, including:

If the initial connection type of the first external network port is the connection subrack type, the network connection is changed to the network management server type, and the vlanid of the external network port in the connection state is changed to the external vlanid; If the initial connection type of the network port is the type of the network management server, the connection type of the first external network port is not modified.

Optionally, the modifying the connection type of the first external network port is a connection subrack type, including:

In the method for automatically switching the connection mode of the external network port in the embodiment of the present invention, in the process of modifying the connection type of the first external network port, first, it is necessary to determine whether the initial connection type of the first external network port and the connection type to be modified are Consistent, if they are consistent, they will not be modified; if they are inconsistent, they will be modified to the corresponding connection type.
