specified bootfile. If the unicast attempts fail, or if a TFTP server address was not provided, 
Auto Install process stops. No Broadcast attempts are made.
Note:  
The bootfile is required to have a file type of *.cfg. The bootfile 
cannot have the following names: fastpath.cfg, startup-config, and 
hpc_broad.cfg. These names are reserved
Default Network Configuration File
If the specified bootfile or the bootfile name from the DHCP server cannot be found, the 
switch tries to download the default network configuration file (fp-net.cfg). The switch issues 
TFTP requests for a network configuration file in the same manner as it attempts to download 
a host-specific configuration file.
The default network configuration file should have IP address to host-name mappings using 
the command ip host <hostname> <address>. If the default network configuration file does 
not contain the switch IP address, the switch uses DNS to attempt to resolve its host name.
A sample fp-net.cfg file follows:
config
...
ip host switch_to_setup 192.168.1.10
ip host another_switch 192.168.1.11
... <other hostname definitions>
exit
Once a host name has been determined, the switch then issues a TFTP request for a file 
named <hostname>.cfg file, where <hostname> is the first eight characters of the switch’s 
host name.
If the switch is unable to map its IP address to a host name, Auto Install sends TFTP requests 
for the default configuration file host.cfg.
The following table summarizes the config files that can be downloaded, and the order in 
which they are sought.
