[0061] In order to make the methods described in this application accurately and fully understood, the professional knowledge involved in the technical field of this application is first introduced and explained in detail.

[0062] When testing the overall performance of a switch, it is necessary to ensure that all service ports of the switch have traffic flowing in and out. For example, a common operation is to configure a traffic flow on the test port T1, with the destination MAC address set to the MAC address of the test port T2. In this way, the service port G1 connected to T1 has traffic flowing in, and the service port G2 has traffic flowing out. This is the forward traffic between T1 and T2. Configure another traffic flow on T2, with the destination MAC address set to the MAC address of T1. Then, G2 has traffic flowing in, and G1 has traffic flowing out. This is the reverse traffic between T1 and T2. And so on, so that each service port has traffic flowing in and out.

[0063] Start the test instrument to send multiple flows to the switch. After receiving the flow, the service port will return the flow to the test instrument according to the above configuration. Then the test instrument will analyze the flow according to actual needs, thereby achieving the purpose of testing the performance of the entire switch.

[0064] However, there are several problems with the usual operation: the test instrument must have the same number of test ports as the service ports of the switch. As the port density of the current switch is increasing, it is actually difficult to find a test instrument with enough test ports for testing. In addition, each service port of the switch needs to be connected. If the optical port is tested, each port needs to be equipped with an optical module, and the cost of the test accessories is high. When the switch has many types of service ports (such as optical ports, electrical ports, etc.), different types of service ports require different cables to connect, which also requires the test instrument to have the same type of test ports, which places high requirements on the test instrument. In addition, configuring multiple flows on the test instrument is both complicated and error-prone.

[0065] In order to overcome the above problems, the present application provides a method for testing switch performance. The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0066] Embodiment 1: This application discloses a method for testing switch performance.

[0067] For details, please refer to Figure 1a A method for testing switch performance disclosed in this embodiment includes the following steps:

[0068] Step 101: Connect a test port T1 of a test instrument to G1, and configure port loopbacks on G2 to Gn.

[0069] In the method described in this embodiment, the switch includes multiple ports G1 to Gn, and only one test port T1 is connected to G1 for connection. Port loopback is configured on G2 to Gn, that is, all other service ports except G1 connected to T1, so that the traffic flowing out of the port flows into the port again. As an optional method, when G2 to Gn are optical ports, optical fiber can be used for physical loopback connection.

[0070] Step 102: Configure VLAN hybrid mode in G1 to Gn.

[0071] VLAN hybrid mode means that when a data frame enters the switch from a hybrid port, the switch will first check whether the data frame has a VLAN tag. If the data frame has a VLAN tag, the switch will search the MAC address table based on the VLAN ID in the tag to determine which port the data frame should be forwarded to. If the data frame has no tag, the switch will mark it with a PVID (Port VLAN ID) and regard it as belonging to the VLAN corresponding to the PVID. Accordingly, when the data frame leaves the switch from the hybrid port, the switch will determine whether the VLAN tag needs to be stripped based on the port configuration and the VLAN ID of the data frame. If the port is configured to allow data frames of the VLAN to leave in untagged mode, the switch will strip the VLAN tag of the data frame. If the port is configured to leave in tagged mode, the data frame will remain tagged.

[0072] In the method described in this embodiment, Figure 1b The schematic diagram of the principle of a method for testing switch performance disclosed in an embodiment of the present application is shown in FIG. Figure 1b As shown, in G1 to Gn, that is, all service ports are configured with VLAN hybrid mode, specifically, the corresponding pvid and untag can be configured. As an optional method, the pvid of G1 is configured as VLAN 1, untag is VLAN n, the pvid of G2 is configured as VLAN 2, untag is VLAN 1, the pvid of G3 is configured as VLAN 3, untag is VLAN 2, ..., the pvid of Gn is configured as VLAN n, untag is VLAN n-1.

[0073] Step 103: Configure traffic at T1, start the test instrument to send the traffic to the switch, and receive return traffic sent back by the switch.

[0074] In the method described in this embodiment, first configure the link protocol of T1 to make the link layer state available. As an optional method, taking the data transmission between T1 and G2 as an example, configure a flow at T1 and send it from T1 to G1. According to the pvid configured for G1, set the label of the flow to vlan 1, and the flow is flooded in vlan 1. The vlan 1 label corresponds to the port untagged as vlan1. Therefore, the flow can be sent from G1 to the port G2 untagged as vlan 1.

[0075] In the method described in this embodiment, according to the port loopback configured by G2, the traffic can flow into G2 again after flowing out from G2. Specifically, after receiving the traffic, G2 strips off the vlan 1 tag of the traffic, and flows the untagged traffic out of G2 and then flows in. Subsequently, according to the pvid configured by G2, the traffic is sent to the port G3 whose untag is vlan 2. The traffic is then looped back according to the port configured by G3, and flows out of G3 and then flows into G3. The transmission of the above traffic is repeated continuously, so that the traffic is transmitted in a serpentine manner until the traffic flows through all service ports according to the vlan forwarding rules and reaches the last service port Gn. According to the pvid configured by Gn, the tag of the traffic is set to vlan n, and the traffic is flooded in vlan n. The traffic is sent from Gn to the port G1 whose untag is vlan n, that is, it flows back into G1 as return traffic, and G1 then outputs the return traffic to T1. At this point, all service ports of the switch have traffic flowing in and out.

[0076] Step 104: Evaluate the performance of the switch according to the return traffic.

[0077] The method described in this embodiment only needs to dock a test port of the test instrument with a service port of the switch to complete the test, which greatly reduces the requirements for the number of test ports of the test instrument. And the type of the test port only needs to be the same as the type of the docked service port, so the requirements for the test port type are also reduced, and the electrical port and optical port of the switch can be tested at the same time. At the same time, only one flow (unicast, multicast, and broadcast) needs to be configured on the test instrument, which simplifies the flow configuration, has no restrictions on the flow type, and reduces the configuration time. In summary, the method described in this embodiment not only reduces the dependence on the number and type of test ports of the test instrument, simplifies the flow configuration, but also reduces the use of accessories such as test wires and optical modules, greatly saves test resources, and reduces the cost of testing. In addition, the port loopback feature of the switch is utilized, that is, the flow sent from the port can be internally looped back and enter from the port without physical connection. At the same time, combined with the vlan tag addition / stripping processing method of the vlan hybrid mode, the flow of any vlan id can be configured to realize vlan tag stripping. Combining the port loopback feature with the vlan hybrid feature can further optimize the test effect.

[0078] Embodiment 2: This application discloses another method for testing switch performance. Figure 2 The method described in this embodiment introduces the traffic transmission process in the switch performance test.

[0079] Step 201: After the test instrument is started, traffic is output from the test port T1 of the test instrument and output to the service port G1 of the switch connected to T1.

[0080] Step 202: According to the pvid (vlan 1) configured by G1, the traffic is labeled with the vlan 1 label.

[0081] Step 203: Traffic is output from G1 and input to service port G2 which is untagged as vlan 1.

[0082] Step 204: According to the port loopback configured on G2, the traffic is stripped of the VLAN 1 label, outputs G2 in an unlabeled form, and re-enters G2.

[0083] Step 205: According to the pvid (vlan 2) configured by G2, the traffic is labeled with the vlan 2 label.

[0084] Step 206: Traffic is output from G2 and input to service port G3 which is untagged as vlan 2.

[0085] Step 207: Repeat the above steps until the traffic is output from Gn and input to G1 with untag vlan n.

[0086] Step 208: According to the untag vlan n configured in G1, the traffic is stripped of the vlan n tag, output from G1 in an untagged form, and input into T1.
