Chapter 3: Basic Switch Parameters
58 Section I: Basic Operations
The following prompt is displayed:
DHCP/BOOTP/DISABLE: (1-DHCP, 2-BOOTP, 3-DISABLE):
4. Type 1 to enable DHCP, 2 to enable BOOTP, or 3 to disable the
services and press Return. The default is disabled.
Note
If you activated BOOTP or DHCP, the switch immediately begins to
query the network for a BOOTP or DHCP server. The switch
continues to query the network for its IP configuration until it
receives a response.
Any static IP address, subnet mask, or gateway address assigned to
the switch is deleted from the System Configuration menu and
replaced with the value the switch receives from the BOOTP or
DHCP server. If you later disable BOOTP and DHCP, these values
are returned to their default settings.
5. After making changes, type R until you return to the Main Menu. Then
type S to select Save Configuration Changes.
