Retrieving an IP Address from a BOOTP Server  
The standard BOOTP protocol is supported and enables the switch to automatically download its IP host configuration 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. 
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.  
When the device reboot begins, any input at the ASCII terminal or keyboard automatically cancels the BOOTP process 
before completion and the device does not receive an IP address from the BOOTP server. 
The following example illustrates the process: 
DGS3100# 
config dhcp_auto enable
DGS3100# reboot 
This command will reset the whole system and disconnect your current session.Do you 
want to continue (y/n)[n]? 
Enter Y to reboot the switch.******************************************************
