Dynamic virtual local area network connection process

Abstract

Method and apparatus for dynamically connecting a system under test (“SUT”) to and disconnecting an SUT from a private virtual local area network (“VLAN”) in a computer manufacturing environment are described. In a preferred embodiment, each time an SUT disposed in a burn rack boots up, a VLAN-capable switch (hereinafter “CAT”) connected thereto checks the media access control (“MAC”) address of the SUT against a MAC address-to-VLAN correlation table (“MAC-VLAN table”). If the SUT's MAC address is not listed in the MAC-VLAN table, the CAT connects the SUT to a predefined default VLAN; i.e., the manufacturer's main manufacturing network. If the SUT's MAC address is included in the MAC-VLAN table, there is a private VLAN associated with the SUT and the CAT connects the SUT to the associated VLAN in a conventional fashion, at which point custom configuration can be performed as needed on the private VLAN. The MAC-VLAN correlation is performed as follows. When an SUT is moved from the assembly line to the burn rack, it is connected to the CAT and then booted from a configuration and diagnostics disk (hereinafter “step diskette”). The step diskette for each SUT on which custom configuration is to be performed includes two unique commands thereon; namely, a dv_connect command, which initiates connection of the SUT to an associated private VLAN to enable the custom configuration processes to be performed, and a dv_disconnect command, which initiates disconnection of the SUT from the private VLAN once the custom configuration has been completed.
