See the following fields: - The host name of the TFTP server (option 66 or sname). Either the TFTP address or name is specified, not both, in most network configurations. If a TFTP host name is given, a DNS server is required to translate the name to an IP address. - The IP address of the TFTP server (option 150). - The address of the TFTP server (siaddr) to be used for Auto Install requests. You can also enter this information manually. No DHCP configuration is saved in the startup-config file.
