DELL CONFIDENTIAL – PRELIMINARY 8/9/16 - FOR PROOF ONLY
Triggering the Auto Update of Configuration/Image File Process
When the Auto-Update feature is enabled (in the Auto Update of
Configuration/Image File
page), the device automatically attempts to
download a new image or configuration file (under certain circumstances)
using one of the following processes:
•
The Auto-Update process is triggered from the USB drive if a USB key in
the USB drive is found.
• The Auto-Configuration process
is triggered from the USB drive after the
Auto-Update process completed and the device was rebooted (if a new
image file was loaded), and if the following conditions are fulfilled:
– There is a USB key in the USB drive.
– Force Configuration Download at Next Startup has been enabled in
the Auto-Update page or the Startup Configuration file is empty.
See Performing Auto-Update from a USB Drive.
• The Auto-Update from a TFTP server is triggered if the following
conditions are fulfilled:
– An IP address of a TFTP server is received from a DHCP server.
– A file name is received from DHCP server.
• The Auto-Configuration from a TFTP server is triggered if the following
conditions are fulfilled:
– The switch as DHCP client received a configuration file name or a
TFTP URL.
– Force Configuration Download at Next Startup is enabled in the
Auto-Update page.
– The Startup Configuration file is empty.
See Preparations for Using Auto Configuration from a TFTP Server .
NOTES:
• DHCP client never triggers the Auto-Update process from a TFTP server
after attempting (whether successfully or not) to auto-update/configure
configuration/image file from the USB drive.
• If the auto process involved setting the IP address of the device from the
setup file, the auto process from the TFTP server can be triggered.
