Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] The method provided by the present invention can troubleshoot faults in the VXLAN through remote mirroring.

[0035] see figure 1 , figure 1 The flow chart of the method provided by the present invention. Such as figure 1 As shown, the process may include the following steps:

[0036] In step 101, the VXLAN access device receives data packets through a local user access port.

[0037] In this application, a user access port refers to a port for accessing a user such as a server or a virtual machine.

[0038] In step 102, the VXLAN access device determines whether there is a local mirroring policy matching the user access port.

[0039] In this application, as an embodiment, when it is necessary to perform mirroring processing on the d...

Abstract

The invention provides a fault analysis method and device applied to a VXLAN (Virtual eXtensible LAN). By setting a VXLAN mirroring dedicated tunnel, data messages which are received by VXLAN access equipment and need mirroring can be conveniently and uniformly mirrored to VXLAN core equipment, and the data messages are finally forwarded to traffic monitoring equipment for fault analysis by the VXLAN core equipment, so that the fault in the VXLAN can be simply and effectively checked.

Description

technical field [0001] The present application relates to network communication technology, and in particular to a fault analysis method and device applied in a scalable virtual local area network (VXLAN: VirtualeXtensible LAN). Background technique [0002] VXLAN is a Layer 2 VPN technology based on IP network and adopts "MAC in UDP" encapsulation. Based on the existing service provider or enterprise IP network, VXLAN provides Layer 2 interconnection for dispersed physical sites and provides service isolation for different tenants. VXLAN is mainly used in data center networks. [0003] The VXLAN network model includes at least VXLAN access devices and VXLAN core devices. VXLAN access devices and VXLAN core devices are interconnected, and data streams are transmitted between VXLAN access devices and VXLAN core devices through VXLAN tunnels. [0004] In VXLAN, there is no way to troubleshoot VXLAN faults. Contents of the invention [0005] The present application provid...
