• ip-address - IP address

identifies the host address bits used for routing to specific subnets.
• bootp - Obtains IP address from BOOTP.
• dhcp - Obtains IP address from DHCP.

Command Mode
Interface Configuration (VLAN)
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.
