AutoInstall

The AutoInstall feature enables the configuration of a switch automatically whenever the device is turned
on and no configuration file is found in device storage during the boot process. By communicating with a
DHCP server, AutoInstall obtains an IP address for the switch and an IP address for a TFTP server. AutoInstall
attempts to download a configuration file from the TFTP server and install it on the switch.
The DHCP server that the switch communicates with must provide the following information:
• The IP address and subnet mask (option 1) to be assigned to the switch.
• The IP address of a default gateway (option 3), if needed for IP communication.
• The identification of the TFTP server from which to obtain the boot file. This is given by any of the
following fields, in the priority shown (highest to lowest):
• The sname field of the DHCP reply.
• The hostname of the TFTP server (option 66). Either the TFTP address or name is specified – not both
– in most network configurations. If a TFTP hostname 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 supplied in the siaddr field.
• The name of the configuration file (boot file or option 67) to be downloaded from the TFTP server. The
boot file name must have a file type of *.cfg.
• The IP addresses of DNS name servers (option 6). The IP addresses of DNS name servers should be
returned from the DHCP server only if the DNS server is in the same LAN as the switch performing
AutoInstall. A DNS server is needed to resolve the IP address of the TFTP server if only the "sname" or
option 66 values are returned to the switch.
After obtaining IP addresses for both the switch and the TFTP server, the AutoInstall feature attempts to
download a host-specific configuration file using the boot file name specified by the DHCP server. If the
switch fails to obtain the file, it will retry indefinitely.
