-
After rebooting the device when stateless DHCPv6 client is enabled.
•
When the DHCPv6 server packets contain the configuration filename
option.
•
The Auto Image Update process is triggered when an indirect image file
name is provided by the DHCP server or a backup indirect image file name
has been configured. Indirect means that this is not the image itself, but
rather a file that holds the path name to the image.
Auto Configuration Image Update in a Stack
The current master of a stack is responsible for the Auto Configuration/Image
Update of the whole stack.
For auto configuration, the new configuration file is downloaded to the master unit
and synchronized to backup before reload.
For auto image update, the new image is copied and saved to the inactive-image
of the master unit. As the part of the copy process the master unit synchronizes
the image to all the units in the stack before the reload.
A configuration file that is placed on the TFTP/SCP server must match the form
and format requirements of the supported configuration file. The form and format
of the file are checked, but the validity of the configuration
parameters
is not
checked prior to loading it to the Startup Configuration.
