Service configuration method, device and system

摘要

The present invention discloses a service configuration method, apparatus and system. The provided method includes steps as follows: configuring a VLAN ID of a port on an intermediate device according to preset configuration information, where the port is connected to a client; after a DHCP request message which is from the client through the intermediate device is received, obtaining a MAC address in the DHCP request message, and obtaining an IP address corresponding to the MAC address from the configuration information; and sending a response message carrying the IP address and the VLAN ID to the client through the intermediate device, so that the client sets a local virtual local area network identifier to the VLAN ID and sets a local IP address to the IP address after receiving the response message.

1. A local area network system, comprising:
a dynamic host configuration protocol (DHCP) server, an intermediate device and a client, wherein the client is connected to the DHCP server through the intermediate device; the DHCP server is configured to configure a virtual local area network identifier (VLAN ID) of a port on the intermediate device according to preset configuration information, wherein the port is connected to the client, receive a DHCP request message from the intermediate device, wherein the DHCP request message carries the VLAN ID, obtain a media access control (MAC) address from the DHCP request message, obtain an IP address corresponding to the MAC address from the configuration information, and send a response message to the intermediate device, wherein the response message carries the IP address and the VLAN ID; the intermediate device is configured to modify the DHCP request message by including the VLAN ID and send the modified DHCP request message to the DHCP server, wherein the DHCP request message is from the client; and send the response message to the client; and the client is configured to send the DHCP request message to the port on the intermediate device, receive the response message, set a local virtual local area network identifier to the VLAN ID and set a local IP address to the IP address.
