Problems solved by technology

[0008] However, for a network divided into virtual LANs, because the virtual LAN isolates the broadcast domain of the broadcast message, the newly deployed client does not know the virtual local area network where the DHCP server is located, and cannot obtain the IP information of the management interface from the DHCP server. Limitations of Technology Application in Virtual Local Area Network Environment

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] For such as figure 2 or as image 3 In the shown local area network, the physical network is divided into three (for example only, there may be one or more) virtual local area networks, VLAN1-VLAN3. Assume that VLAN1 is the management virtual local area network, VLAN2 is the broadband virtual local area network, and VLAN3 is the voice virtual local area network. The DHCP server 20 that allocates the device management interface IP is deployed in the virtua...

Abstract

The present invention discloses a method, device and system for service configuration. The provided method includes: configuring the Virtual Local Area Network Identity (VLAN ID) of the transfer device port connected to a client according to configuration information; After a DHCP request message from the client is received by means of the transfer device, acquiring the Media Access Control (MAC)address in the DHCP request message and acquiring the Internet Protocol (IP) address corresponding to the MAC address from the configuration information; sending the response message containing the IP address and the VLAN ID to the client by means of the transfer device, to enable the client to set the local virtual local area network identity as the VLAN ID and set the local IP address as the IPaddress after receiving the response message.

Description

technical field [0001] The present invention relates to the communication field, in particular to a service configuration method, device and system. Background technique [0002] At present, the access network shows a trend of deploying equipment to the user side. The equipment deployed at the user end is networked with the central office equipment through various technologies. One technology adopted by the industry is Ethernet technology. The IEEE802.1Q standard defines a virtual local area network technology. By dividing a physical network into multiple virtual local area networks, it is possible to limit message broadcasting and differentiate service bandwidth. When deploying a new device, it is necessary to configure the VLAN (Virtual Local Area Network, Virtual Local Area Network) identifier carried by different service packets of the device, so that different service packets can be correctly forwarded to the corresponding virtual local area network. In addition to pro...
