DNA Center without internet connection

[taytibob]

What are the limitation of using DNA Center without access to the cloud (no internet access) ?

Can i still make the updates to DNA center manually ?

I have not done that.

However DNAC does not need internet access, it only need access to specific Cisco resources for upgrade that's all, so you can block entire internet except these 5-6 URLs

See table 7 in link below.

I believe that you can make upgrades with no Internet connectivity. To do so, however, you will need to contact TAC so that they can provide you with a link for the software download.

HTH,

Ah, I see what you are talking about.

I have done that using USB, formatted using etcher tool (image was provided by TAC), this was initially when I got new DNAC which came with older version, it was more like an fresh install of a new higher version than an upgrade with all existing configurations restored.

Please post your experience after your upgrade.
