Zorluk: ZorCisco DNA Center Enabled Device Management

A network administrator is executing an automated software upgrade for a cluster of Cisco Catalyst access switches using Cisco DNA Center Software Image Management (SWIM). What is the correct sequence of steps required to complete the complete end-to-end SWIM deployment workflow?

  1. 1Upload the target Cisco IOS XE software image file into the Cisco DNA Center Image Repository.
  2. 2Designate the imported software image as 'Golden' for the specific Catalyst switch model family.
  3. 3Initiate the Image Distribution job to copy the binary file from Cisco DNA Center to the switch flash storage.
  4. 4Run the Pre-checks validation to verify flash memory space, hardware compatibility, and system readiness.
  5. 5Execute the Image Activation job to set new boot variables, reboot the switch into the new software version, and run Post-checks.

Cevap

The correct operational order for the Cisco DNA Center Software Image Management (SWIM) workflow is: 1) Upload the software image file into the Cisco DNA Center Image Repository, 2) Designate the software image as Golden for the specific Catalyst switch model family, 3) Initiate the Image Distribution job to copy the binary file to switch flash storage, 4) Run Pre-checks validation to verify system readiness, and 5) Execute the Image Activation job to set boot variables, reboot the device, and run Post-checks.
The Cisco DNA Center SWIM lifecycle follows a strict logical process. First, the installation file is uploaded into the central repository. Next, administrators tag the image as 'Golden' for the targeted switch family to establish compliance baseline. Then, distribution transfers the binary onto the managed switch's local storage. Pre-checks validate storage capacity and configuration state prior to disruption. Finally, activation updates boot parameters, reloads the node into the new release, and executes post-checks to confirm full network recovery.

Adım Adım Çözüm

1
Add the installation binary to the system repository
The target Cisco IOS XE image is stored in Cisco DNA Center Image Repository
Cisco DNA Center cannot manage, evaluate compliance for, or deploy an image that has not been imported into its local repository.
2
Set the Golden Image compliance standard
The image is marked as Golden for the selected device family
Marking an image as Golden defines the standardized baseline operating system version for all devices assigned to that family/role.
3
Distribute the software image to target switches
The image binary file is transferred to local flash memory on the switches
Distribution moves the image onto the device storage in advance so that activation can take place swiftly during a designated maintenance window.
4
Run Pre-upgrade check validations
System checks confirm sufficient disk space, configuration compatibility, and stack stability
Pre-checks prevent failed upgrades by identifying potential issues (such as insufficient flash storage or corrupt configuration statements) before the reboot sequence starts.
5
Activate the image and run Post-checks
Boot configuration is modified, device reboots, and Post-checks confirm healthy status
Activation updates the startup system boot statements and reboots the switch to complete the upgrade, followed by post-check verification to validate operational health.
