Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] In the embodiment of the present invention, when all the links between the PE device and the CB device fail and / or the handshake with the global main control board fails, the PE device is not restarted immediately, but enters the delayed start state . In the delayed start state, restart the PE device with a delay, and continue to detect the link status between the PE device and the CE device and the handshake status with the global main control board. If both of them exit the delayed start state normally, and restart the PE device, avoid frequent restarts of the PE device, thereby improving service availability.

[0032] Moreover, in the embodiment of the present invention, the PE device supports Layer 2 and Layer 3 local forwarding. When the PE device is...

Abstract

An embodiment of the invention provides a method and a device for rebooting a PE (port extender). The method comprises the following steps: the PE is in a delay start state when abnormal communication with a CB (core backbone) device is determined according to a detection mechanism, and whether the communication with the CB device returns to normal is determined according to the detection mechanism; when the condition that the communication with the CB device returns to normal is determined, the PE quits from the delay start state and is rebooted.

Description

technical field [0001] The embodiments of the present invention belong to the technical field of network communication, in particular to a method and device for restarting a port extender (Port Extender, PE) device. Background technique [0002] It is an important development trend of current data center technology to realize functions such as single management domain, network layer reduction and management flattening through virtualized access network. In order to meet the requirements of the data center, a two-level stacked core backbone (Core Backbone, CB)-PE networking solution has emerged. [0003] In the CB-PE networking of the prior art, if all links between the PE device and the CB device fail, the PE device is restarted immediately. Moreover, if the global main control board detects that the handshake with the board where the PE device is located has timed out, it will also restart the PE device immediately. [0004] After the PE restarts, if the link failure betw...
