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.
