2. Enter the subnet mask for the network connected to the
LAN Ethernet interface in the
Net Mask
field.
The subnet mask specifies which bits of the 32-bit binary IP
address represent network information. Most sites should use
255.255.255.0 for their subnet mask.
If you have turned on Expert Mode on the Cayman 2E-W Home
window, you will see a set of DHCP fields on the Ethernet Port
Configuration (LAN) window. If you did not turn on Expert Mode,
you can skip to Step 8, below.
If you use the Cayman 2E-W as a DHCP server, you should
assign IP addresses outside the DHCP address range to
devices requiring static IP addresses. Before the Cayman
2E-W assigns an IP address to a DHCP client, it verifies that
no other device is using that address. However, network
conflicts can result when the Cayman 2E-W assigns an
address in its DHCP range to one device and then another
device configured to use that address is turned on.
3. Use the DHCP Mode buttons to specify whether you want
your Cayman 2E-W to act as a DHCP server or DHCP relay
agent for other devices on your local area network.
Options are:
Off
– Disable DHCP server functions in the Cayman 2E-W.
Server
– Cayman 2E-W uses DHCP to provide network
configuration information to hosts on the Local Area
Network.
Server
is the default setting.
Relay-agent
– Cayman 2E-W forwards DHCP requests to a
remote DHCP server and sends responses back to hosts
asking for configuration information.
4. If you chose
Server
in Step 3, enter the first IP address the
Cayman 2E-W should assign for Dynamic Host Control
Protocol clients in the
Start Address field.
5. If you chose Server in Step 3, enter the last IP address the
Cayman 2E-W should assign for Dynamic Host Control
Protocol clients in the
End Address
field.
