AutoInstall
The AutoInstall feature enables the configuration of a switch automatically when the device is turned on
and, during the boot process, no configuration file is found in device storage. By communicating with a
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 in 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—not both—is
specified 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
