    Hi,

    Which flash does a 3810 boot from when powered up (ie not from a cli boot command)? Its primary by default, but if we use 'boot set-default flash secondary' will it then boot from secondary image when it powers up? Or, will it ALWAYS cold boot from primary and only boot from secondary when the boot command is issued?

    And, is the config file synchronised by default between primary & secondary flash? So, if we are running on primary flash and save configs, is that config saved to both primary AND secondary flash?

    there is one config file. The same file is being used for the primary and secondary boot image.

    The command boot set-default flash will change the default flash. This isn't just for one boot. It will then always boot from the secondary flash
