IPv4 Interface

â—† If bootp or dhcp options are selected, the system will immediately
start broadcasting service requests for all VLANs configured to obtain
address assignments through BOOTP or DHCP. IP is enabled but will not
function until a BOOTP or DHCP reply has been received. Requests are
broadcast periodically by the router in an effort to learn its IP address.
(BOOTP and DHCP values can include the IP address, default gateway,
and subnet mask). If the DHCP/BOOTP server is slow to respond, you
may need to use the ip dhcp restart client command to re-start
broadcasting service requests, or reboot the switch.
EXAMPLE
In the following example, the device is assigned an address in VLAN 1.
Console(config)#interface vlan 1
Console(config-if)#ip address 192.168.1.5 255.255.255.0
Console(config-if)#
