Difficulty: MediumCisco DNA Center Enabled Device Management

A network administrator needs to perform a Software Image Management (SWIM) upgrade on enterprise switches using Cisco DNA Center. What is the correct chronological sequence of steps required to complete this software deployment workflow from start to finish?

  1. 1Import the target software image file into the Cisco DNA Center Image Repository.
  2. 2Mark the imported software image as a Golden Image for the specific switch family.
  3. 3Run pre-checks on target devices to verify storage capacity and operational readiness.
  4. 4Distribute the software image to the target switch local flash memory.
  5. 5Activate the software image to reboot the switch and apply the new software version.

Answer

The correct sequence for a Cisco DNA Center Software Image Management (SWIM) upgrade is: 1) Import the software image into the Image Repository, 2) Mark the image as Golden for the device family, 3) Run pre-checks on target devices, 4) Distribute the software image to the switch storage, and 5) Activate the software image to reboot the switch into the new version.
The correct workflow in Cisco DNA Center Software Image Management (SWIM) begins with importing the software binary into the repository, followed by marking it as a Golden Image for the target device family to set compliance standards. Next, pre-checks are run to ensure devices have sufficient storage space and satisfy health conditions. Once verified, the image is distributed (staged) to the target storage, and finally activated to reboot the switch into the updated software version.

Step-by-Step Solution

1
Import the software image into Cisco DNA Center.
The binary image file is indexed within Cisco DNA Center's Image Repository.
Cisco DNA Center requires image files to reside in its repository before they can be evaluated or assigned.
2
Tag the image as Golden for the target hardware platform.
Devices running older or non-matching code are flagged as non-compliant.
Golden image tagging establishes the compliant baseline version within the network hierarchy.
3
Perform readiness pre-checks on candidate switches.
Flash storage, running configuration integrity, and hardware compatibility are verified.
Pre-checks prevent distribution or activation failures due to insufficient memory or incompatible settings.
4
Initiate image distribution.
The software file is copied across the network onto the switch flash storage.
Staging the file beforehand allows distribution to occur prior to a scheduled maintenance window.
5
Execute image activation.
Boot configuration is updated and the switch reboots using the new software image.
Activation completes the upgrade cycle by rebooting the hardware to run the distributed binary.
