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.
The AT-8024 and AT-8024GB Fast Ethernet Switches support these
protocols and can obtain their IP configuration information from a
BOOTP or DHCP server on your network. If you activate this feature, the
switch will seek 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 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 5 to select System Config Menu.
