The following message might appear if you delete a network that was previously configured in the switch thru Mist Portal.

- Cosmetic issue, will not affect switch functionality.

We have to identify and do the proper changes at API level, please find the steps below.

1-) Go to Mist portal> Access the switch in question> Right click anywhere on the page> click inspect (or just press F12 once you access the switch)

2-) A new window will be display, please look for the Network option and select that.

4-) Then you have to refresh the page so we can load the API's, you can press F5 or click on the refresh bottom of your browser.

5-) In the search bar you need to put 0000 in order to narrow down at API level.

6-) Select the API, then you have to check under "Response Headers" that the "Allow:" field has the "PUT" option so we can actually make changes on that API.

7-) Inside the API you need to locate the network name that Mist is reporting in the warning message. In this case we can assume that the network "test-l3" is the one Mist is warning us about, so we have to take this network out the API and push the change thru the same. Delete what is highlighted and click PUT.

Should look like this:

The warning message should be gone by now.

***Note: If the warning message still there, then check the API and make sure that the network name does not appear in the API code. Sometimes the network in question can be under "other_ip_configuration" section of the API code, so that needs to be fully taken out.
