Changing the assigned DHCP IP
address range
Use this procedure to program the layer-2 switch (NET 3)
of the 3100 ICP system to support a different DHCP IP
address range. This procedure changes the default
layer-2 switch IP address (192.168.1.2) to match the
customer’s required LAN subnet addressing. In this
example, the phones and PC’s use the DHCP service on
the 3100 ICP system and all devices are plugged into the
3100 ICP system. The programming must be performed
though the WAN port through a crossover cable.
