Obtaining an IPv4 Address

If you select the “bootp” or “dhcp” option, IP will be enabled but will not function until a BOOTP or DHCP reply has been received. You therefore need to use the “ip dhcp restart” command to start broadcasting service requests. Requests will be sent periodically in an effort to obtain IP configuration information. (BOOTP and DHCP values can include the IP address, subnet mask, and default gateway.)

If the “bootp” or “dhcp” option is saved to the startup-config file (step 6), then the switch will start broadcasting service requests as soon as it is powered on.

To automatically configure the switch by communicating with BOOTP or DHCP address allocation servers on the network, complete the following steps:

1.From the Global Configuration mode prompt, type “interface vlan 1” to access the interface-configuration mode. Press <Enter>.

2.At the interface-configuration mode prompt, use one of the following commands:

•To obtain IP settings via DHCP, type “ip address dhcp” and press <Enter>.

•To obtain IP settings via BOOTP, type “ip address bootp” and press <Enter>.

3.Type “end” to return to the Privileged Exec mode. Press <Enter>.

4.Type “ip dhcp restart” to begin broadcasting service requests. Press <Enter>.

5.Wait a few minutes, and then check the IP configuration settings by typing the “show ip interface” command. Press <Enter>.

6.Then save your configuration changes by typing “copy running-config startup-config.” Enter the startup file name and press <Enter>.
