Configuration File Download Details
The switch will attempt to download a host-specific configuration file first. If not
possible, it will download configuration file <hostname>.cfg if Default Network
Configuration Mode is enabled.
Host-specific Configuration File
The switch attempts to download the host specific configuration file whose name
is specified as the bootfile name in the reply from a DHCP/BOOTP server, or is
configured as the Backup Configuration File for DHCP Auto Configuration. The
switch makes three unicast TFTP requests for the specified bootfile. If the unicast
attempts fail, or if a TFTP server address was not provided, the switch makes
three broadcast requests to any available TFTP server for the specified bootfile.
When the switch gets the configuration file, the configuration is validated for
errors. If the validation is successful, the switch copies the configuration to the
Startup Configuration file type, stores the configuration file name in non-volatile
memory, and reboots the unit.
The switch requires the bootfile name to be *.cfg.
Default Network Configuration File
If Default Network Configuration Mode is enabled, the switch will download the
configuration file <hostname>.cfg when any one of the following conditions
occurs:
•
A host specific configuration file is not specified or configured.
•
A host specific configuration file does not exist on the TFTP server.
•
A failure occurs during the download.
To resolve the hostname in the configuration file, the switch first downloads
fp-net.cfg from the TFTP server. The fp-net.cfg file is referred as the default
network configuration file and contains one or more IP-address-to-host-name
mappings. The switch determines the hostname from the mappings with its IP
address. If there is no mapping, the switch uses reverse DNS lookup to discover
the hostname.
The following is a sample fp-net.cfg file.

ip host switch_to_setup 192.168.1.10
ip host another_switch 192.168.1.11
... <other hostname definitions>
