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.
• An interface can have only one primary IP address, but can have many
secondary IP addresses. In other words, you will need to specify
secondary addresses if more than one IP subnet can be accessed via this
interface.
• 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 client command, or by rebooting the router.
Notes: 1. Each VLAN group can be assigned its own IP interface address.
Therefore, if routing is enabled, you can manage the router via
any of these IP addresses.
2. Before you can change the primary IP address on an interface,
you must first clear the current address with the no form of this
command.
Example
In the following example, the device is assigned an address in VLAN 1.
