Configuration 2: One external DHCP server for
two VLANs
Figure 18: VLAN Configuration 2
To configure the SX-200 ICP system to use an external DHCP server (for
example, Windows NT server or Windows 2000 server) through the
Layer 2 switch port, you must use Form 47 to disable the controller’s
built-in DHCP server. The local phones and PCs on the SX-200 ICP LAN
will then be able to receive IP addresses from the external server.
