Embodiment Construction

[0044] In order to make it easier for those skilled in the art to understand and realize the present invention, the embodiments of the present invention are described in conjunction with the accompanying drawings.

[0045] The basis of the present invention is the standard DHCP protocol (RFC1533), so at first a brief introduction is made to the whole process of a dynamic VLAN user going online and offline (that is, the process of a dynamic VLAN user obtaining and releasing an IP address).

[0046]For a VLAN user, its state must be in one of the six state machines of the DHCP protocol at any time, namely initial state (INITIALIZE), selection state (SELECT), request state (REQUEST), binding state (BOUND), re- Bound state (REBIND) and update state (RENEW). Because technology among the present invention is to be used for laboratory test VLAN user's on-line and off-line, so just needn't relate to rebinding state (REBIND) and update state (RENEW) two states, simultaneously SELECT st...

Abstract

The method includes steps: script structures DHCPDISCOVER message; script structures DHCPREQUEST message; broadcasting DHCPDISCOVER message in order to change state into SELECT, and waiting for DHCPOFFER message; based on received DHCPOFFER message, sending DHCPREQUEST message to apply for allocation of IP address in DHCPOFFER. Testing is carried out for multiple devices of supporting VLAN user service by PC through testing script 'under variable definition, flexible structuring' on line message and off line message of dynamic VLAN user. After VLAN user on line, testing can be executed including two way or one way message send receive significance testing under each rate, length of message, one to one, one to many, many to many etc, and each anomaly testing in procedure of VLAN user on line and off line.
