Command Usage

• You must assign an IP address to this device to gain management

access over the network or to connect the switch to existing IP

subnets. You can manually configure a specific IP address, or direct

the device to obtain an address from a BOOTP or DHCP server.

Valid IP addresses consist of four numbers, 0 to 255, separated by

periods. Anything outside this format will not be accepted by the

configuration program.

• If you select the bootp or dhcp option, IP is enabled but will not

function until a BOOTP or DHCP reply has been received. Requests

will be broadcast periodically by this device in an effort to learn its IP

address. (BOOTP and DHCP values can include the IP address,

default gateway, and subnet mask).

• You can start broadcasting BOOTP or DHCP requests by entering an

ip dhcp restart command, or by rebooting the switch.

Note: Before you can change the IP address, you must first clear the

current address with the no form of this command.
