Activating the BOOTP and DHCP Client Software
The BOOTP and DHCP application protocols were developed to simplify
network management. They are used to automatically assign IP
configuration information to the devices on your network, such as an IP
address, subnet mask, and a default gateway address.
An AT-8000 Series switch contains the client software of these protocols
and can obtain IP configuration information from a BOOTP or DHCP
server on your network. If you activate this feature, the switch seeks its IP
address and other IP configuration information from a BOOTP or DHCP
server on your network whenever you reset or power ON the device.
For this to work there must be a BOOTP or DHCP server residing on your
network and you must configure the service by entering in the switch’s
MAC address and other appropriate information.
BOOTP and DHCP application protocols allow you to specify how the IP
address is to be assigned to the switch. Choices are static and dynamic. If
you choose static, the server will always assign the same IP address to
the switch when the switch is reset or powered ON. This is the preferred
configuration. Since the BOOTP and DHCP services always assigns the
same IP address to a switch, you will always know which IP address to
use when you need to remotely manage a particular switch.
If you choose dynamic, the server will assign any unused IP address that
it has not already assigned to another device. This means that a switch
might have a different IP address each time you reset or power cycle the
device, making it difficult for you to remotely manage the unit.
Note
The default setting for the BOOTP and DHCP client software is
disabled.
To activate or deactivate the BOOTP and DHCP client software on the
switch, perform the following procedure:
1. From the Main Menu, type 4 to select Administration Menu.
The Administration in Figure 3 on page 41 is displayed.
2. Type 8 to select BOOTP/DHCP.
The following prompt is displayed:
BOOTP/DHCP (E-Enabled, D-Disabled):
3. Type E to enable BOOTP and DHCP services on the switch or D to
disable the services and press Return. The default is disabled.
