554 DHCP and USB Auto-Configuration
If the switch is unable to map its IP address to a hostname, or no
configuration file has been downloaded, Auto Configuration sends up to
three TFTP requests for the default host-specific configuration file
host.cfg.
Table 15-1 summarizes the config files that may be downloaded and the order
in which they are sought.
Table 15-2 displays the determining factors for issuing unicast or broadcast
TFTP requests.
