console(config)#
console(config-if)#
console(config-if)#
console(config)#
The interface receives the IP address automatically.
1.
To verify the IP address, enter the show ip interface command at the system prompt as shown in the following
example.

Notes: 1. The device configuration does not have to be deleted to retrieve an IP address for the DHCP server.
2. When copying configuration files, avoid using a configuration file that contains an instruction to enable
DHCP on an interface that connects to the same DHCP server, or to one with an identical
configuration. In this instance, the switch retrieves the new configuration file and boots from it. The
device then enables DHCP as instructed in the new configuration file, and the DHCP instructs it to
reload the same file again.
Receiving an IP Address From a BOOTP Server
The standard BOOTP protocol is supported and enables the switch to automatically download its IP host configu-
ration from any standard BOOTP server in the network. In this case, the device acts as a BOOTP client.
To retrieve an IP address from a BOOTP server:
1.
Select and connect any port to a BOOTP server or subnet containing such a server, to retrieve the IP
address.
2.
At the system prompt, enter the delete startup configuration command to delete the startup configuration from
flash. The device reboots with no configuration and in 60 seconds starts sending BOOTP requests. The
device receives the IP address automatically.
