Activating the BOOTP and DHCP Services
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-8300 Series switch supports these protocols and can obtain its IP
configuration information from a BOOTP or DHCP server on your
network. If you activate this feature, a stack 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.
Naturally, 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 Master switch’s MAC address.
BOOTP and DHCP services typically 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 BOOTP and DHCP option is disabled by default on the switch.
To activate or deactivate the BOOTP and DHCP protocols on the switch,
perform the following procedure:
1. From the Main Menu, type 4 to select Administration Menu.
The Administration Menu in Figure 10 on page 43 is displayed.
2. Type 7 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 the Enter key. The default is disabled.
