Abstract

Embodiments of the present invention provide a method and device for switching the communication state of a link aggregation interface, the method including: a user edge CE device determines the link aggregation between the first link aggregation interface of the CE device and the first service edge PE device Whether the link between the interfaces fails; if a link failure occurs, the CE device switches the first link aggregation interface to an inactive state, and connects the CE device to the second PE device. The second link aggregation interface is switched to an active state; the CE device sends a first link aggregation control protocol LACP message to the second PE device through the second link aggregation interface, so that the second PE device according to the The first LACP message switches the link aggregation interface of the second PE to an active state. The link aggregation interface communication state switching method and device provided by the embodiments of the present invention improve the switching speed of inter-device link aggregation.

Description

technical field [0001] The embodiments of the present invention relate to the field of communications, and in particular to a method and device for switching a communication state of a link aggregation interface. Background technique [0002] A customer edge (Customer Edge, CE for short) device is usually a customer end router or switch connected to a service provider. The CE device provides network service access for users by connecting to a service edge (Provider Edge, PE for short) device of a service provider network. A communication link is established between the physical interface of the CE device and the physical interface of the PE device to implement data forwarding. To increase bandwidth and improve communication reliability, the user configures multiple physical interfaces of the CE device and the PE device to be bundled together to form the link aggregation interface of the CE device and the link aggregation interface of the PE device. The CE device and the PE...
