Difficulty: MediumCisco DNA Center Enabled Device Management

A network administrator is using Software Image Management (SWIM) within Cisco DNA Center to upgrade a Catalyst switch. Place the steps of the standard SWIM deployment workflow in the correct operational sequence from first to last.

  1. 1Import or discover the target software image into the Cisco DNA Center image repository.
  2. 2Designate the software image as the 'Golden Image' for the corresponding device family and role.
  3. 3Perform pre-upgrade readiness checks to verify storage capacity, hardware compatibility, and device health.
  4. 4Distribute the software image file from Cisco DNA Center to the local storage of the target device.
  5. 5Activate the software image on the device and initiate a system reboot to complete the upgrade.

Answer

The correct operational sequence for Software Image Management (SWIM) in Cisco DNA Center is: 1) Import or discover the target software image into the Cisco DNA Center image repository, 2) Designate the software image as the 'Golden Image' for the corresponding device family and role, 3) Perform pre-upgrade readiness checks to verify storage capacity, hardware compatibility, and device health, 4) Distribute the software image file from Cisco DNA Center to the local storage of the target device, and 5) Activate the software image on the device and initiate a system reboot to complete the upgrade.
The Cisco DNA Center Software Image Management (SWIM) process follows a logical zero-downtime staging sequence: ingesting the image file into the central controller, tagging it as the Golden Image standard for device role compliance, running automated pre-upgrade checks to validate disk space and device health, distributing the image file to local device flash storage, and finally activating the software image through a boot configuration change and system restart.

Step-by-Step Solution

1
Import the target software image into the Cisco DNA Center repository.
The operating system image binary is ingested and stored centrally.
Cisco DNA Center cannot manage, verify, or push image files until they exist in its software image repository.
2
Designate the imported software image as a Golden Image.
Cisco DNA Center marks device models lacking this software version as non-compliant.
Establishing a Golden Image defines the software standard for a specific physical device model and site function.
3
Run pre-upgrade readiness checks on the target device.
Flash storage capacity, hardware platform compatibility, and network stability are confirmed.
Pre-checks prevent distribution failures caused by missing prerequisites or insufficient disk space.
4
Distribute the image file to the network device.
The image file is staged in the target switch's flash memory.
Transferring the image staged in device flash separates file transfer from the maintenance window reboot.
5
Activate the image and initiate a device reboot.
The device modifies its boot statement and reboots into the new operating system.
Activation finalizes the software upgrade process by applying the newly staged image to operational memory upon reboot.
