Detailed Description
The core of the application is to provide a loopback test method, a device, a circuit, electronic equipment and a computer readable storage medium of a communication equipment network port, so as to realize terminal loopback test of the communication equipment network port with low cost and high quality and obtain the signal quality of a real communication signal.
In order to more clearly and completely describe the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The loop back Test (LoopBack Test) is a debugging Test means for sending out signals from a sending port of a network element and receiving the signals from a receiving port of the network element, and is an important judging mode for carrying out port communication maintenance, checking failure nodes in the ports and judging whether equipment works normally.
However, in the related art, the hardware loop back to the communication device generally has only a loop back near the MAC (Media Access Control ) port, i.e., mac_loop; and loop back (namely PHY_LOOPBACK) near PHY (Physical) port, the loop back is the signal circulation completed in the communication chip, and has larger difference with the loop back at the terminal side of the communication equipment network port, the real condition of the loop back at the terminal of the communication equipment network port cannot be shown by a real entity, and therefore, the real communication signal quality under the influence of the blocking impedance matching and the signal integrity cannot be accurately obtained. Therefore, in the related art, the terminal loop test is performed by adopting a mode of adding an external optical module or an optical fiber loop module, but the test cost is increased undoubtedly. In view of this, the present application provides a loop-back test scheme for a network port of a communication device, which can effectively solve the above-mentioned problems.
Referring to fig. 1, fig. 1 is an application scenario diagram of a loopback testing method of a network port of a communication device according to an embodiment of the present application.
An Ethernet MAC port, a PHY port, a switching circuit module, a communication device port, and a controller are shown in fig. 1. Under the normal communication condition of the system, the Ethernet MAC port, the PHY port, the switch circuit module and the communication equipment network port are sequentially connected to form a normal signal circulation path. In the drawings related to the present application, TX represents a signal transmitting end, and RX represents a signal receiving end.
The controller is connected with the control end of the switch circuit module and used for controlling the on-off state of each switch in the switch circuit module. The loopback test method of the communication equipment network port disclosed by the embodiment of the application is particularly applicable to the controller.
Referring to fig. 2, an embodiment of the application discloses a loopback test method of a communication device network port, where the communication device network port is connected with a PHY port through a switch circuit module, and the method is applied to a controller connected with the switch circuit module, and mainly includes:
s101: and receiving an input channel mode selection instruction.
S102: a switch changeover instruction corresponding to the passage mode selection instruction is determined.
S103: and sending a switch switching instruction to the switch circuit module, and switching the connection state of the signal path between the network port and the PHY port of the communication equipment so as to carry out loopback test under a corresponding mode.
Specifically, the loopback test method of the communication equipment network port provided by the embodiment of the application is realized based on the switch circuit module arranged between the communication equipment network port and the PHY port. As the name implies, the switching circuit module is a switching circuit, in which a plurality of switches are disposed, and by adjusting the on-off states of the respective switches, the switching circuit module can form a plurality of different switching path states.
The controller is connected with the switch circuit module and used for controlling the on-off of each switch in the switch circuit module. The switch circuit module is specifically connected between the network port and the PHY port of the communication equipment, so that the connection state of the signal path between the network port and the PHY port of the communication equipment can be switched by changing the state of the switch path in the switch circuit module, and the loop-back test can be carried out under the signal path of the corresponding mode.
When the state of the switch access in the switch circuit module is changed so as to switch the connection state of the signal access between the communication equipment network port and the PHY port, if the signal access is specifically adjusted at one side of the switch circuit module close to the communication equipment network port, the loop-back test of the terminal network port can be realized; if the signal path is specifically adjusted on the side of the switch circuit module close to the PHY port, the loop-back test of the PHY port can be implemented.
Further, when the signal path is adjusted on the side, close to the network port of the communication device, in the switch circuit module, different signal paths can be specifically selected, so that loopback tests under different path modes can be realized. Therefore, the controller can control the switch circuit module to enter a corresponding signal path connection state according to the received path mode selection instruction by a corresponding switch switching instruction, so that the loop-back test of the corresponding mode is carried out in the signal path connection state.
Moreover, it is easy to understand that the arrangement of the switch circuit module and the controller in the present application does not affect the mac_lock and the phy_lock, that is, the present application not only can normally implement the mac_lock and the phy_lock in the related art, but also can implement the termination loop for the network port of the communication device.
In addition, it is also to be noted that the switch circuit module in the application can be built based on basic components such as a relay, a switch tube and the like, and has the advantage of low cost.
The loopback test method of the communication equipment network port provided by the embodiment of the application is applied to a controller connected with the switch circuit module, wherein the switch circuit module is connected between the communication equipment network port and the PHY port, and the method comprises the following steps: receiving an input channel mode selection instruction; determining a switch switching instruction corresponding to the access mode selection instruction; and sending the switch switching instruction to the switch circuit module, and switching the connection state of the signal path between the network port of the communication equipment and the PHY port so as to carry out loopback test under the corresponding mode.
Therefore, the switching circuit module arranged between the network port of the communication equipment and the PHY port can be used for switching the signal path connection state between the network port of the communication equipment and the PHY port according to the path mode selection instruction selected by a user, and particularly, the signal path adjustment is carried out on one side, close to the network port of the communication equipment, of the switching circuit module, so that the real condition of the terminal loop back signal of the network port of the communication equipment can be tested at low cost and high efficiency under the condition that an optical module, an optical fiber loop back module and the like are not needed to be inserted, and the operation of aging test, model machine debugging, fault node positioning and the like is greatly facilitated.
As a specific embodiment, in the method for testing loopback of a communication device network port according to the embodiment of the present application, if the access mode selection instruction is a single-network port self-loopback mode instruction, the sending the switch switching instruction to the switch circuit module includes:
and sending a first switch switching instruction corresponding to the single-network port self-loop mode instruction to the switch circuit module so as to disconnect the PHY port from the equipment communication network port, and connecting a pair of signal ends of the PHY port with each other through the switch circuit module, wherein the pair of signal ends comprise a signal sending end and a signal receiving end.
Referring to fig. 3, fig. 3 is a schematic diagram of a signal path in a single-port self-loopback mode according to an embodiment of the present disclosure.
Specifically, in the single-port SELF-LOOPBACK mode (i.e., the loop_self mode), the signal link between the switch circuit module and the communication device port is disconnected, and the signal transmitting end and the signal receiving end of the PHY port are connected with each other at one side, close to the communication device port, inside the switch circuit module, so that LOOPBACK is realized. At this time, the breakpoint of the link is close to the network port of the communication equipment, so that the looped-back signal is very close to the signal when the network port of the communication equipment is short-circuited, and the method can be used for realizing aging test, prototype debugging, fault node positioning and the like aiming at the network port of the communication equipment.
It is to be understood that, in this embodiment, the signal transmitting end and the signal receiving end which are connected to each other in the PHY port are a pair of signal ends belonging to the same PHY port.
As a specific embodiment, in the method for testing loopback of a network port of a communication device according to the embodiment of the present application, based on the above content, the PHY port includes a first port and a second port, where the first port includes a first signal transmitting end and a first signal receiving end, and the second port includes a second signal transmitting end and a second signal receiving end;
if the access mode selection instruction is a multi-portal cross loop back mode instruction, the sending the switch switching instruction to the switch circuit module includes:
and sending a second switch switching instruction corresponding to the multi-port cross loop back mode instruction to the switch circuit module so as to disconnect the PHY port from the equipment communication network port, and connecting the first signal sending end with the second signal receiving end through the switch circuit module so as to connect the first signal receiving end with the second signal sending end.
Referring to fig. 4, fig. 4 is a schematic diagram of a signal path in a multi-portal cross loop mode according to an embodiment of the present disclosure.
It should be noted that, in the embodiments of the present application and the first port and the second port mentioned below, two different PHY ports participating in cross loop are meant, and not specifically meant to be two PHY ports. And in general, the first port and the second port participating in the cross-loop may be embodied as two adjacent PHY ports.
Specifically, in the multi-port CROSS-loop mode (i.e., the loop_cross mode), the signal link between the switch circuit module and the communication device port is disconnected, and the signal transmitting end of the PHY first port and the signal receiving end of the second port are connected to each other at a side of the switch circuit module near the communication device port, and the signal receiving end of the PHY first port and the signal transmitting end of the second port are connected to each other, thereby realizing CROSS-loop between the first port and the second port.
Referring to fig. 5, fig. 5 is a schematic diagram of a signal path in a multi-portal cross-loop mode according to an embodiment of the present disclosure.
Further, in the method for testing loopback of a communication device port according to the embodiment of the present application, on the basis of the foregoing, the disconnecting the PHY port from the device communication port includes:
disconnecting the first port from the first device communication network port, and disconnecting the second port from the second device communication network port;
the first equipment communication network port and the second equipment communication network port belong to different virtual local area networks.
The partial circuit in fig. 5 is specifically described as an example. Under normal communication conditions, a first port of the PHY port corresponds to the communication device network port 1, and a second port of the PHY port corresponds to the communication device network port 2. In a multi-port cross loop-back mode, the first port is disconnected with the communication equipment port 1, and the second port is disconnected with the communication equipment port 2; the signal transmitting end of the first port is connected with the signal receiving end of the second port, and the signal receiving end of the first port is connected with the signal transmitting end of the second port.
The monitoring and testing of the full communication flow of the whole board can be realized by matching with VLAN (Virtual Local Area Network ) setting and receiving and transmitting packet testing instruments for the network ports of all communication equipment, and aging test, prototype debugging, fault node positioning and the like can be performed.
It should be noted that, in order to avoid the occurrence of the broadcast storm and other problems, in this embodiment, two communication device ports participating in the cross loop are respectively in different VLANs. For example, communication device portal 1 is in VLAN1 and communication device portal 2 is in VLAN 2.
Furthermore, in order to avoid communication blocking and traffic cannot circulate, in this embodiment, two communication device ports that do not participate in cross-loop are commonly disposed in the same VLAN. For example, the communication device portal 2 and the communication device portal 3 that do not participate in cross-loop are both in VLAN 2.
As a specific embodiment, in the method for testing loopback of a network port of a communication device according to the embodiment of the present application, if a path mode selection instruction is a normal communication mode instruction, a switch switching instruction is sent to a switch circuit module, where the method includes:
and transmitting a third switch switching instruction corresponding to the normal communication mode instruction to the switch circuit module, so that the signal transmitting end of the PHY port is connected to the signal receiving end of the corresponding communication equipment network port through the switch circuit module, and the signal receiving end of the PHY port is connected to the signal transmitting end of the communication equipment network port through the switch circuit module.
Referring to fig. 6, fig. 6 is a schematic diagram of a signal path in a normal communication mode according to an embodiment of the present application.
Specifically, in the NORMAL communication mode (i.e., bypass_dis or NORMAL mode), the signal link between the switch circuit module and the network port of the communication device is normally connected, i.e., there is no substantial difference from the NORMAL communication device, and the related circuits in the switch circuit module will not affect the communication signal.
As a specific embodiment, in the method for testing loopback of a communication device network port according to the embodiment of the present application, if the access mode selection instruction is a BYPASS mode instruction, the method sends a switch switching instruction to the switch circuit module, including:
and sending a fourth switch switching instruction corresponding to the BYPASS mode instruction to the switch circuit module so as to disconnect the PHY port from the device communication network port, and connecting a first signal sending end and a second signal sending end of the PHY port through the switch circuit module so as to connect a first signal receiving end and a second signal receiving end of the PHY port.
Referring to fig. 7, fig. 7 is a schematic diagram of a signal path in BYPASS mode according to an embodiment of the present application.
The BYPASS is a network port BYPASS technology, specifically, after a communication device triggers a preset condition (typically, the device is powered off or fails significantly), the relevant ports are directly and physically connected, so that signals connected to the communication device are mutually conducted, and interruption of data transmission is avoided.
Specifically, in the BYPASS mode (i.e., bypass_en mode), the signal link between the switch circuit module and the communication device network port is disconnected, the signal transmitting ends of two different PHY ports are connected to each other, and the signal receiving ends of two different PHY ports are connected to each other. Thus, signals of other communication devices connected in series to the communication device can still circulate normally, so that the network of the user can still be used.
Referring to fig. 8, an embodiment of the application discloses a loopback testing device of a communication device network port, where the communication device network port is connected with a PHY port through a switch circuit module, and the device includes:
a receiving module 201, configured to receive an input channel mode selection instruction;
a determining module 202, configured to determine a switch switching instruction corresponding to the path mode selection instruction;
and the sending module 203 is configured to send a switch switching instruction to the switch circuit module, and switch a connection state of a signal path between the network port and the PHY port of the communication device, so as to perform a loopback test in a corresponding mode.
Therefore, the loop-back testing device for the communication equipment network port disclosed by the embodiment of the application can switch the signal path connection state between the communication equipment network port and the PHY port according to the path mode selection instruction selected by the user by using the switch circuit module arranged between the communication equipment network port and the PHY port, and particularly, the signal path adjustment is carried out on one side, close to the communication equipment network port, of the switch circuit module, so that the real condition of the loop-back signal of the terminal end of the communication equipment network port can be tested with low cost and high efficiency under the condition that an optical module, an optical fiber loop-back module and the like are not needed to be inserted, and the operation of aging test, sample debugging, fault node positioning and the like is greatly facilitated.
For the specific content of the device for testing the loopback of the network port of the communication device, reference may be made to the detailed description of the method for testing the loopback of the network port of the communication device, which is not repeated here.
