Problems solved by technology

The seemingly convenient ZTP function is often challenged in practical applications. If the ZTP server fails, all switches cannot be configured normally. Some patents use two ZTP servers to back up each other, but this method is still Unable to prevent network connection error between ZTP server and switch

Embodiment Construction

[0035] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention will be further described in detail below with reference to the specific embodiments and the accompanying drawings.

[0036] Based on the above purpose, in the first aspect of the embodiments of the present invention, an embodiment of a method for ZTP backup is proposed. figure 1 Shown is a schematic flow diagram of the method.

[0037] like figure 1 As shown in, the method may include the following steps:

[0038] S1 divides the switches connected to the ZTP server into several groups and saves the group information in the DHCP server, so that the switches in each group are connected to each other and communicate with each other. Generally, there are multiple switches connected to the ZTP server, and these switches are divided into several Group, the number of switches in each group can be the same or different...

Abstract

The present invention provides a method and equipment for ZTP backup. The method comprises the following steps: dividing switches connected to ZTP servers into several groups and storing the group information in the DHCP server, so that the switches in each group are connected to each other and Communication; in response to the request that the switch sends an invitation DHCP packet to DHCP, the DHCP server sends the DHCP packet and group information to the switch; in response to the timeout of the request that the switch sends an invitation ZTP packet to the ZTP server, the switch sends the group information to the group where the switch is located based on the group information. The other switch of the switch sends a request to invite the ZTP packet; in response to the switch receiving the ZTP packet of the switch sent by the other switch, the switch performs switch configuration based on the ZTP packet of the switch. By using the solution of the present invention, the problem that the switch cannot successfully obtain the configuration file when the ZTP server fails or the network connected to the ZTP fails can be avoided, and the product performance can be made more stable and reliable.

Description

technical field [0001] The art relates to the computer field, and more particularly to a ZTP backup method and device. Background technique [0002] ZTP (Zero touch provisioning zero-touch provisioning) is a management function in the field of switches, which enables switches to automatically configure or install images after power-on, without the need for administrators to intervene. It is especially important during deployment. The main principle is that after the device is powered on, it obtains the IP address of the ZTP server through DHCP (Dynamic Host Configuration Protocol), so that the device can automatically obtain the configuration file from the ZTP server and update the configuration independently. LLDP (Link Layer Discovery Protocol) is a link layer protocol, which organizes the information of the local device into TLV (type, length, value) and encapsulates it in LLDPDU (Link Layer Discovery Protocol Data Unit, link layer discovery). The protocol data unit) is ...
