Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The present invention will be described in detail below with reference to specific examples.
Referring to fig. 1, fig. 1 is a schematic flowchart of an interface connection method according to an embodiment of the present invention, which is applied to a network device, such as an interface of the network device shown in fig. 2, where the network device may include more than one interface, and each interface corresponds to a PHY chip and a PHY media module.
Here, the interface of the network device is generally an optical communication interface, and the PHY media module is connected to an optical fiber, in which case the PHY media module may be an optical module.
Specifically, the method may include:
s100: receiving an interface reverse connection instruction, wherein the interface reverse connection instruction comprises a first interface identifier;
s200: determining an interface to be reversely connected according to the first interface identifier;
s300: and reversely connecting a differential signal line between the physical layer chip and the physical layer medium module corresponding to the interface to be reversely connected, and setting the interface to be reversely connected as a private interface.
When the network device leaves the factory, the interface of the network device is as shown in fig. 2, and the connection manner of the differential signal line between the PHY chip and the optical module (i.e., the PHY media module) corresponding to the interface of the network device may be positive connection, that is, the P pole and the P pole of the differential signal line between the PHY chip and the optical module are connected, and the N pole are connected, where the interface may be a network interface, and the network device may communicate with devices outside the device group through the positive connection interface of the differential signal line to forward network data.
Referring to fig. 3, fig. 3 is a schematic diagram of reverse connection of differential signal lines of an interface of the network device shown in fig. 2, in which the differential signal lines between the PHY chip and the optical module are connected in reverse, that is, the P pole and the N pole of the differential signal lines between the PHY chip and the optical module are connected, at this time, the interface is set as a private interface, that is, the network device may communicate with other network devices in the device group through the reverse connection of the differential signal lines, operate a private protocol, perform configuration management, and the like.
The connection mode of reverse connection of the differential signal line between the PHY chip and the PHY medium module can invert the differential signal, namely, an interface for reverse connection of the differential signal line is obtained, and a connection mode different from the positive connection of the differential signal line can be provided for network equipment. The interfaces with different connection modes can be applied to different scenes, for example, other network devices in the connection device group use interfaces with reversely connected differential signal lines, and network devices outside the connection device group use interfaces with positively connected differential signal lines, so that the interfaces applied to different scenes are the interfaces with the reversely connected differential signal lines. Because only the interfaces with the consistent differential signal lines are connected for communication, even if the interfaces applied to different scenes are connected through a medium, namely, the interface in which the differential signal lines are normally connected is connected with the interface in which the differential signal lines are reversely connected, the message can be discarded because the message from the interface at the opposite end cannot be analyzed, the message cannot be uploaded to a CPU for processing, and further, the network equipment is effectively prevented from being broken down.
Based on the above reasons, even if the network interface and the private interface are connected together due to misoperation, the network device will not send the message received by the private interface from the network interface (or the message received by the network interface from the private interface) to the CPU for processing, thereby effectively avoiding the network device from malfunctioning.
It should be noted that, the forward connection and the backward connection of the differential signal lines are a relative concept, and the interface where the differential signal lines are connected in the forward direction may also be an interface of the network device shown in fig. 3, in this case, the interface where the differential signal lines are connected in the backward direction may refer to the interface of the network device shown in fig. 2.
In an embodiment of the present invention, the reverse connection of the differential signal lines between the PHY chip and the PHY media module, such as the interface of the network device shown in fig. 4, is implemented by configuring an electronic switch and a switch control device connected to the electronic switch in the interface. It should be noted that, one switch control device may control a plurality of electronic switches, one electronic switch corresponds to one interface, in order to accurately reverse a differential signal line between a PHY chip and a PHY media module (such as an optical module shown in fig. 4) corresponding to a to-be-reversed interface, a processor of a network device may determine a control bit of the to-be-reversed interface according to an interface reverse connection instruction after receiving the interface reverse connection instruction, that is, convert the interface reverse connection instruction into a control bit of the to-be-reversed interface, and set the control bit of the to-be-reversed interface to 1 if the control bit 1 indicates reverse connection, and issue the control bit of the to-be-reversed interface to the switch control device corresponding to the to-be-reversed interface; therefore, the switch control device can control the electronic switch of the interface to be reversely connected according to the control bit of the interface to be reversely connected, and reversely connect the differential signal line between the PHY chip and the PHY medium module corresponding to the interface to be reversely connected.
The CPLD (Complex Programmable Logic Device) has the advantages of flexible programming, high integration level, short design and development period, wide application range, advanced development tool, low design and manufacturing cost, low requirement on hardware experience of a designer, no need of testing a standard product, strong confidentiality, high price and the like, so the switch control Device can be a CPLD.
In another embodiment of the present invention, the reverse connection of the differential signal line between the PHY chip and the PHY media module, such as the interface of the network device shown in fig. 5, is implemented by configuring a control register in the interface, and the control register may be disposed on the PHY chip. In this case, in order to implement the reverse connection of the differential signal line between the PHY chip and the PHY media module corresponding to the interface to be reversely connected, the processor of the network device may directly set the indication bit in the control register of the interface to be reversely connected to the reverse connection, so that the control register may implement the reverse connection of the differential signal line between the PHY chip and the PHY media module (such as the optical module shown in fig. 5) corresponding to the interface to be reversely connected according to the indication bit.
Referring to fig. 6, based on fig. 1, the interface connection method may further include:
s400: receiving an interface forward connection instruction, wherein the interface forward connection instruction comprises a second interface identifier;
here, the second interface identifier and the first interface identifier may be any interface in the network device, and the second interface identifier and the first interface identifier may be the same or different.
It should be noted that S400 may be executed before any step of S100, S200, or S300, or may be executed after any step of S100, S200, or S300, which is not limited in this embodiment of the present invention.
S500: determining an interface to be connected positively according to the second interface identifier;
s600: and the interface to be positively connected is set as a network interface by a differential signal line between the physical layer chip and the physical layer medium module corresponding to the interface to be positively connected.
Generally, when an electronic switch and a switch control device connected to the electronic switch are configured in an interface, after a processor of a network device receives an interface forward connection instruction, a control bit of the interface to be forward connected can be determined according to the interface forward connection instruction, that is, the interface forward connection instruction is converted into the control bit of the interface to be forward connected, if the control bit 0 indicates forward connection, the control bit of the interface to be forward connected is set to be 0, and the control bit of the interface to be forward connected is issued to the switch control device corresponding to the interface to be forward connected; therefore, the switch control device can control the electronic switch of the interface to be positively connected according to the control bit of the interface to be positively connected, and is positively connected with the differential signal line between the PHY chip and the PHY medium module corresponding to the interface to be positively connected;
when the interface is configured with a control register, the processor of the network device can directly set the indication bit in the control register of the interface to be connected in the positive direction, so that the control register can realize the positive connection of the differential signal line between the PHY chip and the PHY medium module of the interface to be connected in the positive direction according to the indication bit.
It should be noted that one PHY chip may correspond to one interface, as shown in fig. 2; the PHY chip may also correspond to a plurality of interfaces, as shown in fig. 7, the PHY chip corresponds to two interfaces, where the two interfaces corresponding to the PHY chip are independent from each other, the differential signal lines of one interface are connected in reverse, and the differential signal lines of the other interface may be connected in a positive or reverse manner.
By applying the embodiment, the network equipment receives the interface reverse connection instruction, determines the interface to be reversely connected, and reversely connects the differential signal line between the PHY chip and the PHY medium module corresponding to the interface to be reversely connected. Therefore, interfaces with different connection modes can exist in the network equipment, and the interfaces with different purposes can select different connection modes, thereby effectively avoiding the network equipment from faults.
