Starting and Configuring the Device 55NOTE: It is not necessary to delete the device configuration to retrieve an IP address from the DHCPserver.NOTE: When copying configuration files, avoid using a configuration file that contains an instruction toenable DHCP on an interface that connects to the same DHCP server, or to one with an identicalconfiguration. In this instance, the device retrieves the new configuration file and boots from it. Thedevice then enables DHCP as instructed in the new configuration file, and the DHCP instructs it to reloadthe same file again.Receiving an IP Address From a BOOTP ServerThe standard BOOTP protocol is supported and enables the device to automatically download itsIP host configuration from any standard BOOTP server in the network. In this case, the device actsas 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 retrievethe IP address.2 At the system prompt, enter the delete startup configuration command to delete the StartupConfiguration from flash.The device reboots with no configuration and in 60 seconds starts sending BOOTP requests.The device receives the IP address automatically.NOTE: When the device reboot begins, any input at the ASCII terminal or keyboard automaticallycancels the BOOTP process before completion and the device does not recieve an IP address from theBOOTP server.The following example illustrates the process:console> enableConsole# show ip interfaceGateway IP Address Activity status--------------------- ------------------10.7.1.1 ActiveIP address Interface Type------------------- ------------ ------------10.7.1.192/24 VLAN 1 Static10.7.2.192/24 VLAN 2 DHCP
