BOOTP or DHCP server. BOOTP and DHCP values can include the IP address, subnet
mask, and default gateway. 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.
Note that the "ip dhcp restart client" command can also be used to start
broadcasting service requests for all VLANs configured to obtain address
assignments through BOOTP or DHCP. It may be necessary to use this command
when DHCP is configured on a VLAN, and the member ports which were previously
shut down are now enabled.
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.
Wait a few minutes, and then check the IP configuration settings by typing the
"show ip interface" command. Press <Enter>.
5.
Then save your configuration changes by typing "copy running-config startup-
config. " Enter the startup file name and press <Enter>.
Console(config)#interface vlan 1
Console(config-if)#ip address dhcp
Console(config-if)#end
Console#show ip interface
