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—such as an IP address, subnet mask, and a
default gateway address—to the devices on your network.
An AT-8400 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, 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 cycle the switch.
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. The MAC address is located on a sticker on the
power supply cover (on the front of the chassis).
BootP and DHCP services typically allow you to specify how the IP
address is assigned to the switch. The choices are static and dynamic. If
you choose static, the server always assigns the same IP address to the
switch when the switch is reset or powered ON. This is the preferred
configuration. Because the BootP and DHCP services always assigns the
same IP address to a switch, you know which IP address to use when you
need to remotely manage a particular switch.
If you specify the IP address as dynamic, the server assigns the switch
any unused IP address. As a result, 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
By default, the BootP and DHCP option is disabled 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 is displayed in Figure 4 on page 48.
2. From the Administration Menu, 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. Then press Return. The default is disabled.
