•
Automatically downloading a configuration file from a TFTP server when the switch is booted with
no saved configuration file.
•
Automatically downloading an image from a TFTP server in the following situations:
•
When the switch is booted with no saved configuration found.
•
When the switch is booted with a saved configuration that has AutoInstall enabled.
When the switch boots and no configuration file is found, it attempts to obtain an IP address from a
network DHCP server. The response from the DHCP server includes the IP address of the TFTP server
where the image and configuration flies are located.
After acquiring an IP address and the additional relevant information from the DHCP server, the switch
downloads the image file or configuration file from the TFTP server. A downloaded image is
automatically installed. A downloaded configuration file is saved to non-volatile memory.
Note
AutoInstall from a TFTP server can run on any IP interface, including the network port, service
port, and in-band routing interfaces (if supported). To support AutoInstall, the DHCP client is
enabled operationally on the service port, if it exists, or the network port, if there is no service
port.
