Auto Install Configuration
Auto Install is a software feature that provides for the configuration of a switch automatically 
when the device is initialized and no configuration file is found on the switch. The downloaded 
configuration file is not distributed across a stack. When an administrator saves configuration, 
the config file is distributed across a stack.
The Auto Install process requires you to enable DHCP. The downloaded config file is not 
automatically saved to startup-config. An administrator must explicitly issue a save request to 
save the configuration. The Auto Install process depends on the configuration of other devices in 
the network, including a DHCP or BOOTP server, a TFTP server and, if necessary, a DNS 
server.
There are three phases to Auto Install:
1. 
Configuration or assignment of an IP address for the device.
2. 
Assignment of a TFTP server.
3. 
Obtaining a configuration file for the device from the TFTP server.
Switch IP Address Assignment
If BOOTP or DHCP is enabled on the switch and an IP address has not been assigned, the 
switch issues requests for an IP address assignment. The behavior of BOOTP or DHCP with 
respect to IP address assignment is unchanged by the addition of the Auto Install feature. 
That is, the following information returned from the server is recognized.
•     
The IP address (yiaddr) and subnet mask (option 1) to be assigned to the switch
•     
The IP address of a default gateway (option 3), if needed for IP communication. Some 
network configurations require the specification of a default gateway through which some 
IP communication can occur. Option 3 of a BOOTP or DHCP response specifies the 
default gateway.
After an IP address is assigned to the switch, if a host name is not already assigned, then 
Auto Install issues a DNS request for the corresponding host name. This host name is also 
displayed as the CLI prompt the same as if the hostname command was used.
