Hello, if the question relates to an SD-Access Fabric, then you're correct, you need to delete the old subnet and create a new one. During the creation process you can nominate the VLAN name and number to match the deleted ones, if you wish. In SD-Access UI, under the question mark menu in the top right corner, there is a "Make a Wish" button, which you can use to provide feedback to the product owners. You could use that to suggest/request SD-Access different capabilities if you like. Regards, Jerome
