Configuring Your Cayman 3220-H
3-16
To configure your Ethernet settings:
1. Enter the IP address of the Cayman 3220-H's LAN Ethernet
interface in the Local Address field.
The IP address you assign to your Cayman 3220-H'S LAN
interface must not be used by another device on your LAN
network. The IP address you assign the Cayman 3220-H LAN
interface does not correspond to the IP address associated with
any of the device's hub ports.
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
for their subnet mask.
255.255.255.0
If you have turned on Expert Mode on the Cayman 3220-H 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 3220-H as a DHCP server, you should assign
IP addresses outside the DHCP address range to devices requiring
static IP addresses. Before the Cayman 3220-H 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 3220-H
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 3220-H 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 3220-H.
Server – Cayman 3220-H uses DHCP to provide network
configuration information to hosts on the Local Area
Network. Server is the default setting.
