To facilitate the understanding of the embodiments of the present application, the present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0033] In order to solve the technical problem of how to simplify the complexity of message mirroring in the prior art, the present application provides a message mirroring method, which can simplify the complexity of message mirroring.

[0034] Figure 1 A flow chart of a method for mirroring a message provided in an embodiment of the present application. The method can be applied to one or more electronic devices such as routers and switches. In addition, the execution subject of the method can be hardware or software. When the above-mentioned execution subject is hardware, the execution subject can be one or more of the above-mentioned electronic devices. For example, a single electronic device can execute the method, or multiple electronic devices can cooperate with each other to execute the method. When the above-mentioned execution subject is software, the method can be implemented as multiple software or software modules, or as a single software or software module. No specific limitation is made here.

[0035] like Figure 1 As shown, the method specifically includes:

[0036] Step 101: looping back the mirrored message of the network device to the virtual local area network (vlan) of the network device through the first loopback port of the network device.

[0037] In this embodiment, the network device may be a switch, a router or other device.

[0038] The first loopback port can be any port in the network device that is configured as a loopback port. The loopback port can be a logical, virtual interface (i.e., port) on the above network device. In practice, one or more loopback ports can be created as needed. These loopback ports are treated the same as physical interfaces on the network device. For example, they can be assigned addressing information, including their network numbers in the network device selection update, and even IP (Internet Protocol) connections can be terminated on them. The loopback port can occupy an IP address exclusively.

[0039] Step 102: broadcast the mirrored message through the VLAN, and mirror the mirrored message to the target mirrored port.

[0040] In this embodiment, the target mirror port may be one or more destination ports. As an example, the target mirror port may include one or more local ports of a network device, and / or the target mirror port may also include one or more ports of a remote device. The remote device may be another network device other than the above network device.

[0041] In some implementations of this embodiment, the ingress VLAN check function of the first loopback port is configured to be in a closed state.

[0042] It can be understood that in the above implementation, the ingress VLAN check function of the first loopback port is configured to be in a closed state, which can prevent the mirrored message carrying the VLAN header from being discarded by the VLAN check process.

[0043] In some implementations of this embodiment, before the mirrored message of the network device is looped back to the virtual local area network (VLAN) of the network device through the first loopback port of the network device, the first loopback port is configured as: a member port of the VLAN and a destination port of a mirrored source port, wherein the mirrored source port is a source port for sending the mirrored message.

[0044] It can be understood that for the local mirror port of the network device, after the mirror source port of the network device is configured, the source port can mirror the message. At this time, the mirror destination port of the mirror source port of the network device can be configured as the first loopback port, and the mirror message is looped back through the first loopback port. At this time, the first loopback port belongs to a certain vlan, and other locally required mirror destination ports (that is, target mirror ports) are configured as member ports of this vlan. After the looped-back message enters this vlan, the message will be broadcast and sent within the vlan, so that all subsequent locally required mirror destination ports of the network device can receive this mirror message, so that the same mirror message can be mirrored to one or more different local ports at the same time.

[0045] The message mirroring method provided in the embodiment of the present application can loop back the mirrored message of the network device to the virtual local area network VLAN of the network device through the first loopback port of the network device, and then broadcast the mirrored message through the VLAN so as to mirror the mirrored message to the target mirroring port. Thus, message mirroring can be realized without connecting other external devices, which reduces the complexity of message mirroring.

[0046] Figure 2 A flowchart of another method for mirroring a message provided in an embodiment of the present application. Figure 2 As shown, the method specifically includes:

[0047] Step 201: looping back the mirrored message of the network device to the virtual local area network (vlan) of the network device through the first loopback port of the network device.

[0048] In this embodiment, step 201 and Figure 1 Step 101 in the corresponding embodiment is basically the same and will not be described again here.

[0049] Step 202, when the target mirror port is a local port of the network device, broadcast the mirror message through the VLAN, and directly mirror the mirror message to the local port.

[0050] In this embodiment, the local port may be one or more local ports of the network device.

[0051] In some implementations of this embodiment, the member port of the VLAN is configured with the local port.

[0052] Attach Figure 4 For example, if a network device has a mirror source (either a single port or multiple ports), and needs to be mirrored to the local destination port 1 and destination port 2 of the network device, then the local multi-destination port mirroring can be configured as follows:

[0053] 1. Set the destination port of the mirror source (for example, any destination port) as the first loopback port.

[0054] 2. Add the first loopback port to the internal VLAN used for multi-port mirroring. For example, if VLAN 100 is used, add the first loopback port to VLAN 100.

[0055] 3. Disable the ingress VLAN check function of the first loopback port to prevent the mirrored message from being discarded by the VLAN check function when it carries a VLAN header.

[0056] 4. Add multiple local destination ports 2 and 3 to vlan100.

[0057] 5. At this time, the mirrored traffic of the mirrored source will be looped back to vlan100 through the first loopback port, and vlan100 will broadcast and send the message to multiple local destination mirrored ports.

[0058] It should be noted that, in addition to the above contents, this embodiment may also include Figure 1 The corresponding technical features described in the corresponding embodiments are realized Figure 1 For details, please refer to the technical effect of the mirroring method of the message shown. Figure 1 For the sake of brevity, the relevant description is not repeated here.

[0059] The message mirroring method provided in the embodiment of the present application, for the local mirror port of the network device, after the mirror source port of the network device is configured, the source port can mirror the message out, and at this time the mirror destination port of the network device can be configured as the first loopback port, and the mirror message is looped back through the first loopback port. At this time, the first loopback port belongs to a certain VLAN, and other locally required mirror destination ports (that is, target mirror ports) are configured as member ports of this VLAN. After the looped-back message enters this VLAN, the message will be broadcast and sent within the VLAN, thereby, all locally required mirror destination ports of the network device can receive the mirror message, so that the same mirror message can be mirrored to one or more different local ports at the same time.

[0060] Figure 3 A flowchart of another method for mirroring a message provided in an embodiment of the present application is shown below. Figure 3 As shown, the method specifically includes:

[0061] Step 301: looping back the mirrored message of the network device to the virtual local area network (vlan) of the network device through the first loopback port of the network device.

[0062] In this embodiment, step 301 and Figure 1 Step 101 in the corresponding embodiment is basically the same and will not be described again here.

[0063] Step 302: when the target mirror port is a port of a remote device, broadcast the mirror message through the VLAN.

[0064] In this embodiment, the remote device may be one or more other network devices except the above network devices.

[0065] 303. Send the mirrored message to the second loopback port through the VLAN, wherein the second loopback port is a loopback port in the network device corresponding to the remote device.

[0066] In this embodiment, the second loopback port may be any loopback port in the network device that is different from the first loopback port.

[0067] 304 , encapsulate the mirrored message through the second loopback port, and loop back the encapsulated message to the forwarding chip of the network device.

[0068] 305 , mirroring the mirrored message to the port of the remote device through the forwarding chip.

[0069] In this embodiment, for the port of the remote device, message encapsulation (such as SPAN, ERSPAN and other mirroring methods) is required, and at this time, it corresponds to the required encapsulation type of the remote loopback. At this time, a mirror message will be sent to the second loopback port, and the message type that needs to be encapsulated is configured on the inlet side of the second loopback port. After the mirror stream passes through the second loopback port, it will be encapsulated with the message header of the remote mirror. At this time, the forwarding chip can be used to look up the table, and it can be sent to the remote device according to the path required by the mirror port of the remote device (that is, the above-mentioned target mirror port).

[0070] In some implementations of this embodiment, the member ports of the VLAN include the second loopback port, the encapsulation type configured on the second loopback port is the encapsulation type corresponding to the remote device, and only one encapsulation type is configured on each second loopback port.

[0071] As an example, you can use the following method to set up multi-destination port mirroring on a remote device:

[0072] 1. If the remote mirroring destination is ERSPAN mirroring.

[0073] 2. Set the second loopback port as a vlan100 member port.

[0074] 3. Disable the ingress VLAN check function of the second loopback port to prevent the mirrored message from being discarded by the VLAN check function when it carries a VLAN header.

[0075] 4. Set the second loopback port ERSPAN to encapsulate the remote device IP address and other information.

[0076] 5. Set the chip routing table related remote ERSPAN routing and other information.

[0077] 6. At this time, the mirrored message of the mirrored source will be looped back to vlan100 through the first loopback port, and vlan100 will broadcast the message to the second loopback port. The second loopback port will loop back and add the ERSPAN message header information. After the forwarding chip searches the chip routing table, it will find the remote device route and forward it from the current network device to the remote device.

[0078] 7. If there is another remote device 2 (that is, another remote device) and SPAN remote mirror encapsulation is required, the third loopback port loopback3 is added to the vlan in the same way, and the SPAN encapsulation configuration is configured on loopback3. The message will be looped back to vlan100 through the first loopback port in the same way, and vlan100 will broadcast the message to the third loopback port. The third loopback port will loop back and add the SPAN message header information. After the forwarding chip searches the chip routing table, it will find the remote device route and forward it from the current network device to the remote device 2.

[0079] 8. Similar to step 7, if more remote devices need to be added, just add the corresponding loopback ports and configure them in vlan100, and configure the encapsulation information related to the added loopback ports on the loopback ports.

[0080] It can be understood that for the port of the remote device, since it is necessary to perform message encapsulation (such as SPAN, ERSPAN and other mirroring methods for encapsulation), at this time, it corresponds to the required encapsulation type of the remote loopback. Therefore, the second loopback port can be configured to belong to the member port for the local destination port broadcast VLAN mentioned above. At this time, a mirror message will be sent to the second loopback port. At this time, the message type that needs to be encapsulated is configured on the inlet side of the second loopback port. After the mirror stream passes through the second loopback port, it will be encapsulated with the message header of the remote mirror. At this time, the forwarding chip can be used to look up the table, and it can be sent to the remote device according to the path required by the port of the remote device.

[0081] In some implementations of this embodiment, the mirrored message may be mirrored to the port of the remote device through the forwarding chip in the following manner:

[0082] First, according to the encapsulation type of the mirror message, the target device address of the remote device is determined through the routing table in the forwarding chip.

[0083] The target device address may be an address of a remote device.

[0084] The routing table includes a correspondence between encapsulation types and device addresses of remote devices, and each remote device corresponds to one encapsulation type.

[0085] Afterwards, the mirrored message is sent to the remote device via the target device address.

[0086] It can be understood that in the above implementation, the correspondence between the encapsulation type and the device address of the remote device is determined by the routing table, thereby, the mirrored message can be mirrored to the port of the remote device through the encapsulation address corresponding to the encapsulation type configured on the second loopback port.

[0087] It should be noted that, in addition to the above contents, this embodiment may also include Figure 1 The corresponding technical features described in the corresponding embodiments are realized Figure 1 For details, please refer to the technical effect of the mirroring method of the message shown. Figure 1 For the sake of brevity, the relevant description is not repeated here.

[0088] The message mirroring method provided in the embodiment of the present application can send the mirrored message to one or more remote devices according to the address required by the port of the remote device through a table lookup by a forwarding chip.

[0089] The following is an illustrative description of the embodiments of the present application, but it should be noted that the embodiments of the present application may have the features described below, but the following description does not constitute a limitation on the scope of protection of the embodiments of the present application.

[0090] First, the technical terms involved in this application are explained as follows:

[0091] Port mirroring technology is to mirror the traffic (i.e., messages) of a port to the destination port completely or according to certain conditions, so that the server or observation device connected to the destination port can monitor the traffic of the port. Mirroring technology can be generally divided into local mirroring and remote mirroring. Local mirroring is to directly mirror the port data on the network device to the destination port, and remote mirroring is to encapsulate the port data on the network device and send it to the remote device for mirroring processing.

[0092] Generally, in the related technologies, the port mirroring function mainly adopts one-to-one mirroring or many-to-one mirroring, that is, there are one or more source ports and only one destination port. In some technologies, the destination port can be an aggregation link port, but although there are multiple aggregation link ports, the mirrored data stream is still one copy, but the bandwidth of the destination port is expanded by means of the aggregation link.

[0093] However, as operators are placing increasingly high demands on the reliability of network equipment, they need to monitor the port traffic of certain network devices in multiple ways at the same time. Therefore, they may access ports through multiple devices for mirroring, and some devices may even be local devices while others are remote devices, and the traffic of a certain port needs to be monitored at the same time.

[0094] In the related art, the traffic sent from the local mirroring destination port can be further decomposed by means of a splitter or external devices, but this method requires other external devices, which is troublesome for networking and cannot solve the problem of simultaneous remote mirroring.

[0095] In view of this, this method enables a mirrored data stream (i.e. the mirrored message) to be sent to multiple destination ports, and the destination ports can be different remote mirrored ports (i.e. the ports of the remote device). This method can be used to observe the mirrored traffic of network devices both locally and remotely, without adding any other external auxiliary equipment.

[0096] This method uses the loopback port inside the device (that is, the first loopback port mentioned above) to introduce the mirrored message into the loopback port, and then sends it from the loopback port to the VLAN for broadcasting, thereby completing local multi-port mirroring. If there is a port that requires remote mirroring, another loopback port (that is, the second loopback port mentioned above) can be added to the VLAN, and the message sent back from the loopback port can be forwarded to the required remote mirror port in the manner of remote message mirroring.

[0097] Specifically, first, for the local mirror port (that is, the local port mentioned above), after setting the mirror source port, the source port can mirror the traffic. At this time, the mirror destination port is set to loopback port 1 (that is, the first loopback port mentioned above). Loopback port 1 needs to be configured not to perform VLAN check (to prevent the mirror message carrying the VLAN header from being discarded by the VLAN check process). The message is looped back through loopback port 1. At this time, the loopback port is set to belong to a certain VLAN, and other locally required mirror destination ports are set as member ports of this VLAN. After the looped-back message enters this VLAN, the message will be broadcast and sent within the VLAN, so that all locally required mirror destination ports can receive this mirror traffic.

[0098] As for the remote port, since message encapsulation is required (such as SPAN, ERSPAN and other mirroring methods), at this time, corresponding to the required encapsulation type of the remote loopback, the configuration loopback port 2 (that is, the second loopback port mentioned above) belongs to the member port used for the local destination port broadcast VLAN mentioned above. At this time, a mirror message will be sent to the loopback port 2. At this time, the message type that needs to be encapsulated is configured on the inlet side of the loopback port 2. After the mirror stream passes through the loopback port 2, the message header of the encapsulated remote mirror can be sent to the remote device according to the path required by the remote mirror port (that is, the above-mentioned target device address) by looking up the table through the switching chip (that is, the above-mentioned forwarding chip).

[0099] Through the above two methods, it is possible to process local multi-port mirroring and remote port mirroring in the network device at the same time. The loopback port resources that need to be consumed can be configured by using the idle ports of the network device itself for internal loopback configuration, or directly using the built-in loopback port resources of certain chips, both of which can achieve the effect of this method.

[0100] The above completes the configuration and implementation of the multi-destination port of the message mirror. The multi-destination port mirroring implemented in this way does not require the use of new external devices, and can complete the processing of multiple remote mirror ports without increasing the computing resource consumption of the network device. It is a very simple and practical mirror processing method.

[0101] Specifically, the application environment of this method is mainly used for the scenario aggregation where the traffic of network devices requires multiple servers to perform mirror monitoring.

[0102] In order to illustrate the effectiveness process and steps of this mechanism, it is further explained in two steps.

[0103] Attach Figure 4 For example, a network device has a mirror source (single port or multiple ports), and needs to mirror to the local destination port 1, destination port 2 of the device, and the port of the remote device:

[0104] The first step is to set up local multi-destination port mirroring:

[0105] 1. Set the destination port of the mirror source to the first loopback port.

[0106] 2. Add the first loopback port to the internal VLAN used for multi-port mirroring. For example, if VLAN 100 is used, add the first loopback port to VLAN 100.

[0107] 3. Disable the ingress VLAN check function of the first loopback port to prevent the mirrored message from being discarded by the VLAN check function when it carries a VLAN header.

[0108] 4. Add multiple local mirror destination ports 2 and 3 to vlan100.

[0109] 5. At this time, the mirrored traffic of the mirrored source will be looped back to vlan100 through the first loopback port, and vlan100 will broadcast and send the message to multiple local destination mirrored ports.

[0110] The second step is to set up remote multi-destination port mirroring:

[0111] 1. If the remote mirroring destination is ERSPAN mirroring.

[0112] 2. Set the second loopback port as a vlan100 member port.

[0113] 3. Disable the ingress VLAN check function of the second loopback port to prevent the mirrored message from being discarded by the VLAN check function when it carries a VLAN header.

[0114] 4. Set the second loopback port ERSPAN to encapsulate the remote device IP address and other information.

[0115] 5. Set the chip routing table related remote ERSPAN routing and other information.

[0116] 6. At this time, the mirrored message of the mirrored source will be looped back to vlan100 through the first loopback port, and vlan100 will broadcast the message to the second loopback port. The second loopback port will loop back and add the ERSPAN message header information. After the forwarding chip searches the chip routing table, it will find the remote device route and forward it from the current network device to the remote device.

[0117] 7. If there is another remote mirroring destination device 2 (that is, another remote device) and SPAN remote mirroring encapsulation is required, then the third loopback port loopback3 is added to the vlan in the same way, and the SPAN encapsulation configuration is configured on loopback3. Then the message will be looped back to vlan100 through the first loopback port in the same way, and vlan100 will broadcast the message to the third loopback port. The third loopback port will loop back and add the SPAN message header information. After the forwarding chip searches the chip routing table, it will find the remote device route and forward it from the current network device to the remote device 2.

[0118] 8. Similar to step 7, if more remote devices need to be added, just add the corresponding loopback ports and configure them in vlan100, and configure the encapsulation information related to the added loopback ports on the loopback ports.

[0119] The above is the processing of setting up multiple local and remote destination mirror ports in the device at the same time. According to this method, you only need to perform corresponding configuration on the device to conveniently complete the forwarding of multiple local destination ports and multiple remote destination mirror devices at the same time. And multiple remote destination mirror devices can support different remote encapsulation forms.

[0120] It should be noted that, in addition to the contents recorded above, this embodiment may also include the technical features described in the above embodiments, so as to achieve the technical effect of the mirroring method of the message shown above. For details, please refer to the above description. For the sake of brevity, it will not be repeated here.

[0121] The mirroring method of the message provided in the embodiment of the present application can simultaneously complete the local multi-purpose mirroring processing through an external device. In addition, the method only needs to perform the relevant configuration of the loopback port and VLAN on the network device to complete the processing of the multi-purpose ports of a certain mirrored traffic, and can simultaneously complete the processing of the local destination mirroring port and the remote destination mirroring port. In addition, during the processing, there is no need to add new equipment, and it will not cause a large load and impact on the network equipment. It is a simple and convenient multi-purpose mirroring implementation method. The use of this technology can improve the maintainability and observability of the network, and has a richer application effect on the mirroring function of the network device. In combination with this technology, it can be applied in various network environments that require mirroring, and this technology can be used in flow mirroring, that is, the mirrored source traffic is finely processed, and the setting of the multi-purpose port is consistent with the processing method of this solution. This method allows the mirroring destination port of the network device to be changed from a traditional port to multiple ports, that is, a same mirrored traffic can be mirrored to multiple different ports at the same time, so that simultaneous observation effects can be provided for multiple different observation service servers. The use of this method can improve the maintainability and observability of the network, and has a richer application effect on the mirroring function of the network device.
