Page 381 highlights
receipt of option 125, the switch downloads the text file from the TFTP server, reads the name of the image file, and downloads the image file from the TFTP server. After the switch successfully downloads and installs the new image, it automatically reboots. The download or installation might fail for one of the following reasons: • The path or filename of the image on the TFTP server does not match the information specified in DHCP option 125. • The downloaded image is the same as the current image. • The validation checks, such as valid CRC Checksum, fails. If the download or installation was unsuccessful, a message is logged. NOTE: In stack of switches, the downloaded image is pushed to all members attached to the stack at the time of download. For members who join the stack after the download, the Stack Firmware Synchronization feature will push the latest image to all members. Obtaining the Configuration File If the DHCP OFFER identifies a configuration file, either as option 67 or in the file field of the DHCP header, the switch attempts to download the configuration file. NOTE: The configuration file is required to have a file type of *.cfg. The TFTP client makes three unicast requests. If the unicast attempts fail, or if the DHCP OFFER did not specify a TFTP server address, the TFTP client makes three broadcast requests. If the DHCP server does not specify a configuration file or download of the configuration file fails, the Auto Configuration process attempts to download a configuration file with the name dell-net.cfg. 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 consists of a set of IP address-tohostname mappings, using the command ip host hostname address. The switch finds its own IP address, as learned from the DHCP server, in the Auto Image and Configuration Update 381
