SD Access Switch Upgrades

[benolyndav]

Hi

So we are running FiAB with eWLC installed, I want to upgrade the IOS-XE image on our 9300/9500 Swithches,  

1. IOS-XE and eWLC image versions must mach ?

2.In DNAC Image repository I see the different image es but dont see any eWLC images downloaded, I have to manually download this and once Switch upgraded then manually upgrade eWLC ???

3.I have added two images, the ios-xe image in image repository has an addon tab it says Addon 4 and also a sub-package which is the eWLC Image for this IOS-XE version 17.12.0.4SPA.bin, does this mean if I upgraded the Switches to this IOS-XE version the eWLC would also be upgraded because of the sub-package or would I still need to maually upgrade the eWLC image?????

Thanks

So in the Addons section I see the eWLC and bug fixes if I select the download I then see verified once download finished, if I the upgrade a Switch running eWLC, does DNAC automatically upgrade both images 9300 and eWLC ??

Thanks

Does the image contain the AP software. ?? whats the order of operation is it the below?

1.9300 IOS-XE image gets upgrade to the selected image

2.eWLC Image gets upgraded automatically 

3.APs get new image pushed from new eWLC image.

Thanks

APSP is separate pack downloadable from CCO repo. but it's only available for WLCs not eWLC

What does that mean please I dont understand.??

Thanks

"3.APs get new image pushed from new eWLC image." is something included in (e)WLC image but there r a lot of cases when update for arbitrary AP's HW new image gets updated via ASPS like it was in AIR-OS case via APs-update packages.

@andy!doesnt!like!uucp 
Is there a way to check if the new image has AP pack included ??

Thanks

that is good Q i'd also like to have n explicit statements from Cisco.

so far i guess it should be as per Recommended Cisco IOS XE Releases for Catalyst 9800 Wireless LAN Controllers - Cisco

FiAB Upgrade with eWLC:
Compatibility: Yes, IOS-XE and eWLC versions must be compatible for FiAB functionality.
Separate Images: DNAC may not always show eWLC images. You might need to download them manually from Cisco.com. However, it's generally recommended to upgrade both together for consistency.
Sub-package: The "Addon 4" with eWLC sub-package simplifies things. Upgrading to this IOS-XE version will automatically upgrade the eWLC to the included version (17.12.0.4SPA.bin).
TL;DR: Upgrade the IOS-XE image with the sub-package. It handles eWLC upgrade automatically.

@nnemrmaika What if there is no Add ons to download (Add on N/A) for the image in DNAC would this mean that the eWLC would need upgrading manually or is the eWLC built into the image as I have used this image on an Edge node and I do see in flash the eWLC files .??

eWLC is supplied as sub-pack. if it's not show in the corresponding section import it manually to dnac
