Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
According to one aspect of the invention, an automatic switching method for external network port connection types is provided, which is applied to a first subframe management board, and the method comprises the steps of monitoring a first external network port pair in a connection state; then, judging whether the first pair of external network ports acquire a device type notification message sent by a second pair of external network ports of which the external device is in a connection state within a preset time period; and finally, when the first pair of external network ports acquire the device type notification message sent by the second pair of external network ports, modifying the connection type of the first external network port according to the device type notification message.
Therefore, the method for automatically switching the connection type of the external network port can automatically identify whether the external network port is connected with the network management server or other sub-rack management boards, and automatically set the parameters of the network port, so as to meet the functional characteristics of the network port required to be connected with the network management server or other sub-rack management boards, thereby avoiding the complexity of manually changing the connection type and resetting the attributes.
As shown in fig. 2, the method includes:
and step S21, monitoring the first pair of external network ports in the connection state.
Any equipment sub-rack comprises a sub-rack management board, and the equipment sub-rack connecting network manager and the equipment sub-rack connecting other equipment sub-racks are connected with the outside through an external network port on the sub-rack management board, as shown in fig. 1. However, the connection relationship between the external network ports on the sub-rack management board and the outside needs to be changed when necessary, for example, the external network port connected to the third equipment sub-rack on the sub-rack management board of the second equipment sub-rack shown in fig. 1 may need to be disconnected to make it in an idle state. In addition, the external network port in the idle state cannot send and receive messages. Therefore, the method of the present invention needs to monitor the network ports in the connection state in real time, that is, to obtain which network ports can send and receive messages in time, so as to prepare for the subsequent processing.
Step S23, determining whether the first pair of external network ports obtains a device type notification message sent by a second pair of external network ports where the external device is in a connected state within a preset time period.
According to the automatic switching method for the external network port connection type, the second external network port pair in the connection state of the external equipment sends the equipment type notification message to the first external network port pair in the connection state of the first sub-rack management board, so that the first sub-rack management board is informed of the equipment type of the external equipment.
Step S25, when the first external network interface pair obtains the device type notification packet sent by the second external network interface pair, modifying the connection type of the first external network interface according to the device type notification packet.
In the method for automatically switching connection types to external network ports according to the embodiment of the present invention, the connection type of the first external network port is changed by determining whether a device type notification message sent by the second external network port, to which the external device is connected, is acquired. If the device type notification message carries sub-rack management board information, when the device type notification message is acquired, determining that the external device is a second sub-rack management board, and modifying the connection type of the first external network port to be a connection sub-rack type; and if the external equipment is not acquired, determining that the external equipment is the network management server, and modifying the connection type of the first external network port into a 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 a device type notification message to inform the sub-frame management board that the opposite end is connected with the network management server, so that the corresponding connection type of the external network port is modified into the connection type of the network management server. Namely, the sub-rack management board and the network management server both send out a device type notification message, and when a first pair of external network ports of the sub-rack management board in a connection state receive the device type notification message carrying sub-rack management board information, the connection type of the first external network port is modified into a connection sub-rack type; when a first external network port of a sub-frame management board in a connection state receives an equipment type notification message carrying network management server information, the connection type of the first external network port is modified into a type of a networking management server.
After step S21, the method further includes:
and sending the device type notification message at regular time through the first pair of external network ports so that a second pair of external network ports of the external device in a connection state receives the device type notification message and modifies the connection type of the second external network port.
Specifically, step S23 includes:
sequentially judging whether message headers of a plurality of messages received by the first pair of external interfaces are preset message headers or not;
selecting the message with the message header as a preset message header, and judging whether the type field of the message with the message header as the preset message header is preset content;
and when the type field is preset content, acquiring a device type notification message sent by a second pair of external network interfaces of the external device in a connection state.
In the process of receiving the message, any external network port in the connection state not only receives the device type notification message, but also receives some other service messages. However, the method for automatically switching the connection type of the external network port according to the embodiment of the present invention only requires the device type notification packet, and therefore, it is necessary to screen the device type notification packet from a large number of packets. The device type message has a specific message header and specific content, and for example, the message frame thereof may be as shown in the following table:
table 1 device type notification message frame format
For example, in a message received from the external network interface, first, a BPDU header is identified, then a typeid field of the message is determined, and if the typeid field of the message is 0x4E435031, the message is a device type notification message.
Preferably, modifying the connection type of the first external network port to be connected to the network management server specifically includes:
judging whether the initial connection type of the first pair of external network ports is the type of connecting a network management server;
if the initial connection type of the first external network port is the connection sub-frame type, modifying the connection sub-frame type into a connection network management server type, and modifying the vlan id of the external network port in the connection state into an external vlan id;
if the initial connection type of the first pair of external network ports is the type of connecting the network management server, the connection type of the first pair of external network ports is not modified.
Preferably, the modifying the connection type of the first external network port is a connection subrack type, and specifically includes:
judging whether the initial connection type of the first pair of external network ports is a connection sub-frame type;
if the initial connection type of the first pair of external network ports is the type of connecting the network management server, modifying the connection type into a connection subrack type, and modifying the vlan id of the first pair of external network ports into an internal vlan id;
if the initial connection type of the first pair of external network ports is the connection sub-frame type, the connection type of the first pair of external network ports is not modified.
In the method for automatically switching the connection types of the external network ports, in the process of modifying the connection types of the first pair of external network ports, whether the initial connection types of the first pair of external network ports are consistent with the connection types to be modified or not needs to be judged, and if so, the initial connection types of the first pair of external network ports are not modified; if not, the corresponding connection type is modified.
