NETGEAR Managed Switches Software Administration Manual, Release 8.0 Obtaining a Config File After obtaining IP addresses for both the switch and the TFTP server, the Auto Install process attempts to download a configuration file. A host-specific configuration file is downloaded, if possible. Otherwise, a network configuration file is used as a bridge to get the final configuration. The methods are described below. Host-Specific Configuration File The switch attempts to download a host-specific configuration file if a bootfile name was specified by the DHCP or BOOTP server. 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. A TFTP broadcast request is a simple TFTP request with broadcast destination MAC address (ff:ff:ff:ff:ff:ff) and destination IP address (255.255.255.255). Note: The bootfile is required to have a file type of *.cfg. Default Network Configuration File Attempts are made to download a default network configuration file with the name fp-net.cfg if the specified bootfile cannot be found, a failure occurs in the download or the switch was not provided a specific bootfile name by the DHCP server. The switch unicasts or broadcasts 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 hostname mappings using the command ip host . If the default network configuration file does not contain the switch IP address, the switch uses DNS to attempt to resolve its hostname. 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 ... exit Once a hostname has been determined, the switch then issues a TFTP request for a file named .cfg file, where is the first eight characters of the switch's hostname.
