DHCP Service
Note:
If this section is grayed out, or you are unable to change any settings, you don't have Net3 Services
installed on your desk. Net3 Services are installed by the installer for ETC's Gateway Configuration
Editor (GCE) software. GCE is available for download from the ETC website.
Eos can provide a DHCP (Dynamic Host Configuration Protocol) address server. DHCP is a TCP/IP pro-
tocol that dynamically assigns an IP address to a network device when it requests one.
This is a small and simple DHCP server that is intended to be used on non-routed networks. It will not
serve IP addresses across a router.
CAUTION:
start more than one DHCP server on a single network (nothing is built-in to DHCP servers to
prevent this from happening). If this occurs, it will result in unstable conditions and possibly
result in network communications failures.
Clicking in the enable box will start the DHCP server in the Eos desk. It will use the settings below to
determine which IP addresses it gives out.
First IP Address- This sets the starting IP address of the range of IP addresses the DHCP server
will give out.
Number of Addresses - This sets how many IP addresses the DHCP server will give out. A set-
ting of 500 means it will give out IP addresses to the first 500 devices that ask for an IP
address.
Subnet Mask - This sets the logical network size vs. the device address. ETC's default is
255.255.000.000 (class B). This is the subnet mask that the DHCP server will give to network
devices.
Routed - If checked, you can use the default gateway box, below, to specify the gateway you
would like DHCP devices to use. If unchecked, the DHCP server will serve the same value for
both the devices IP address and gateway, which is a suitable configuration for non-routed net-
works.
Default Gateway- This specifies the IP address of a router if one is present on your network.
This is the gateway IP address that the DHCP server will send to network devices to use.
If you are on a flat or non-routed network, the Gateway IP address should match the IP
address of the device. In order to configure this DHCP server to send out matching gateway IP
addresses, configure this gateway IP address to match the IP Address Pool field. Then the
DHCP server will give out a gateway IP address that matches the IP address.

All settings in this section require a reboot of the desk before they will take effect.
There should only be a single DHCP server active on a network. It is possible to
