Description
Technical Field
The invention belongs to the technical field of data communication, and particularly relates to an Ethernet link detection method and device
Background
Most ethernet PHY (physical layer) chips currently support an ethernet link detection function, which is based on issuing a detection code stream (e.g., a series of detection signals or a detection pulse), and then by issuing a signal amplitude and the time of the signal being sent back, the impedance of the line and the length of the line can be estimated approximately. Whether the Ethernet physical link installed in the actual engineering is abnormal or not can be judged.
The ethernet line we usually use usually includes 4 twisted pairs, and 1000M (gigabit) ethernet link will fully use these 4 twisted pairs, but in 1000M network, if the devices at both ends of the link are working normally, the success rate of detection is very low. The reason is that under the condition that the link is connected (link), the devices at both ends send data streams (such as idle) to maintain normal connection of the link. As shown in fig. 1, a schematic diagram of a network architecture applied to an ethernet link, where 4 twisted pairs used by the ethernet link are a twisted pair, a twisted pair C, and a twisted pair D, respectively, the device a and the device B are devices at two ends of the ethernet link, and ethernet ports of the device a and the device B are both in a 1000M operating mode, then under a condition that the links are normally connected (link), the ethernet port of the device a sends a data code stream to the ethernet port of the device B, and the ethernet port of the device B also sends a data code stream to the ethernet port of the device a, and these code streams are continuous; therefore, the 4 twisted pairs connected to the ethernet port of each device will receive and transmit data streams. If device a is to initiate an integrity check of the ethernet link, it must send a link check code stream over the 4 twisted pairs after the ethernet port of device a initiates the ethernet link check. However, since the device B does not know that the device a is transmitting the link integrity check code stream, the ethernet port of the device B always transmits the data code stream to the device a. Thus, the signal received by the ethernet port of the device a is the detection code stream reflected by the ethernet port of the device a + the data code stream sent by the ethernet port of the device B. Therefore, the device a cannot distinguish which data code streams are sent from the ethernet port of the device B from the received code streams, and which detection code streams are reflected back after the device a sends the detection code streams, which inevitably leads to failure of the device a in detecting the ethernet physical link.

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.
In a 1000M ethernet network, there are 4 twisted pairs (a pair, B pair, C pair, and D pair) in a common twisted pair, and when the working mode of the ethernet ports of the devices at two ends of the twisted pair is in the 1000M network, and in combination with the network architecture diagram of the ethernet LINK detection application shown in fig. 1, under the condition of LINK connectivity (LINK), both the device a and the device B may use the 4 twisted pairs to send data streams to the other side. In order to avoid the problem that the data code stream affects the link detection, the device a is taken as a device to be tested for illustration, and the gigabit ethernet port of the device a is configured to be in a full duplex mode of 100M (hundred megabytes), at this time, the device a and the device B only transmit and receive the data code stream on the first 2 twisted pairs a and B of the 4 twisted pairs, and respectively configure the working mode of the gigabit ethernet port of the device a to be the normal mode and the cross mode, then, the ethernet link detection of the device a is started to obtain a corresponding first detection result and a second detection result respectively under the condition that the working mode of the gigabit ethernet port of the device a is the normal mode and the cross mode, and obtaining the Ethernet link detection result of the gigabit Ethernet port according to the first detection result and the second detection result, thereby avoiding the problem that the link detection is influenced by the data code stream.
As shown in fig. 2, an embodiment of the present invention provides an ethernet link detection method, where the method includes:
The description of this step is made with reference to fig. 1, where the device a is taken as a device to be tested, and a full duplex mode with a gigabit ethernet port of the device a being hundreds of megabytes is configured, so that after the ethernet LINK between the device a and the device B is connected to LINK, if the device a starts ethernet LINK detection, the device a and the device B only respectively receive and transmit data code streams on the first 2 twisted pairs a and B pairs of the 4 twisted pairs.
In this step, the working mode of the gigabit ethernet port of the device a is configured as a normal mode, and then according to the ethernet protocol, the working mode of the gigabit ethernet port of the device B automatically negotiates as a cross mode, and if the device a starts ethernet link detection, the gigabit ethernet port of the device a sends a data code stream to the gigabit ethernet port of the device B through the a twisted pair of the first 2 twisted pairs, and receives the data code stream from the gigabit ethernet port of the device B through the B twisted pair of the first 2 twisted pairs; and the gigabit ethernet port of the device B receives the data code stream sent from the gigabit ethernet port of the device a through the a pair of twisted pairs, and sends the data code stream to the gigabit ethernet port of the device a through the B pair of twisted pairs. In this step, the working mode of the gigabit ethernet port of the device a may also be configured as the cross mode; then, in step 204, the working mode of the gigabit ethernet port of the device a needs to be configured to be the normal mode, specifically, the working mode of the gigabit ethernet port of the device a needs to be configured to be the normal mode or the cross mode, which is not limited herein.

When the working mode of the gigabit ethernet port of the device a is configured as the normal mode in step 202, in this step, the working mode of the gigabit ethernet port of the device a needs to be configured as the cross mode, then according to the ethernet protocol, the working mode of the gigabit ethernet port of the device B automatically negotiates as the normal mode, if the device a starts ethernet link detection, the gigabit ethernet port of the device a sends a data code stream to the gigabit ethernet port of the device B through the pair B of twisted pairs, and receives the data code stream from the gigabit ethernet port of the device B through the pair a of twisted pairs; and the gigabit ethernet port of the device B receives the data code stream from the gigabit ethernet port of the device a through the twisted pair a and the twisted pair B.
With reference to step 204, in this step, the ethernet LINK detection of the device a is started, after the ethernet LINK of the gigabit ethernet port of the device a is connected to LINK, a detection start command is sent to the device a, and a detection result of 4 pairs of twisted pairs in the register of the gigabit ethernet port of the device a is checked, because the gigabit ethernet port of the device a only receives a data code stream through the a pair of twisted pairs, accuracy of the LINK detection result is affected, and at this time, detection results of remaining 3 pairs (B pair, C pair, and D pair) of twisted pairs, which do not have a data code stream, in the register of the gigabit ethernet port of the device a are accurate, and because the first detection result already includes the detection results of the a pair, the C pair, and the D pair, a detection result of the B pair of twisted pairs, which is not included in the first detection result, is used as a second detection result.
And step 206, obtaining an ethernet link detection result of the gigabit ethernet port according to the first detection result and the second detection result.
In this step, the link detection result of the gigabit ethernet port 4 of the device a to the twisted pair can be obtained according to the first detection result (the detection result of the a pair, the C pair, and the D pair 3 to the twisted pair) in step 203 and the second detection result (the detection result of the B pair not included in step 203) in step 205.
