Abstract

The invention discloses method and client for acquiring VLAN (Virtual Local Area Network) IDs (Identifiers) and network protocol addresses. The method comprises the following steps of: determining that a message sent by a client needs to carry a VLAN ID by the client in the VLAN; sending a plurality of dynamic host configuration protocol (DHCP) DISCOVER messages carrying the VLAN ID to a DHCP server in the VLAN by the client, wherein each DHCP DISCOVER message corresponds to a VLAN ID; and within a first preset time, if the client receives DHCP response messages corresponding to the DHCP DISCOVER messages from the server, acquiring the VLAN IDs and IP addresses. Through the invention, the network configuration efficiency and accuracy are improved.

Description

technical field

[0001] The present invention relates to the field of communications, and in particular, to a method and a client for obtaining a virtual local area network (Virtual Local Area Network, referred to as VLAN) identifier and an Internet Protocol (Internet Protocol, referred to as IP) address. Background technique

[0002] A virtual local area network is a technology that divides a physical network into multiple logical local area networks (Local Area Networks, referred to as LANs for short), and each VLAN has a virtual local area network identifier (VLAN ID). Using VLAN technology, network managers can logically divide users in the same physical local area network into different broadcast domains (each broadcast domain is a VLAN) according to actual application needs, so that users with the same needs are in the same broadcast domain and have different needs. users are in different broadcast domains. Each VLAN is logically like a separate local area network and ...
