Finding the Inactive Partition

A switch can store up to two core images: an active and inactive. When downloading a new image, you must select on which partition to install the new image. You must install the software image to the inactive partition, and must specify that partition while downloading the image to the switch.

To find the inactive partition:

From the CLI, enter the command show switch (or show slot detail on SummitStack).

# show switch
