Fabric SSID address pool

KevinR99 — Tue, 30 May 2023 15:56:18 GMT

I am trying to create a fabric enabled SSID in my SDA fabric. I've created the SSID and made it fabric enabled. However I cannot see how to associate an address pool with the SSID. As I understand the client will join an address pool at the Edge switch and be treated like any wired client. When I go to Fabric sites in DNAC and select SSIDs I can see my SSID but with no Address pool or SGT assigned. However, when I choose the drop down list under Address pool (and Security group) I don't get offered any address pools. I expected to be offered the same address pools that are available in the Port Assignment area for wired clients.

Can anyone shed any light on where I may be going wrong here?

Thanks, Kev.

I believe this video can help you. The answer you are looking for is the wireless profile.

Have you configured the fabric IP Pool under the virtual network as wireless pool?

Unfortunately this video doesn't explain how to attach a pool to the SSID.

Thanks, I found that section, ticked the wireless box and the pool is now available under my fabric site wireless settings.

One more question. I'm sure when I was playing around with this before I managed to create 2 SSIDs with the same name. I can do that manually on the WLC by creating 2 SSIDs with the same name but different profile names. When I try to do this in DNAC, at the point where I define the new SSID under Design - Network settings - Wireless it insists on a unique SSID name. The reason I want the same name is I initially have the WLC managing fabric and non-fabric APs while I migrate my access switches to fabric edge ones. So the SSID will initially be a standard OTT one. As I add Edge switches I then want to change the SSID to fabric in that area with the same name. I know I could migrate all my access switches to fabric edge ones then change the SSID across the campus from OTT to fabric but I want to do a gradual change as I deploy Edge switches.

You can achieve that by creating a single SSID and modifying its type by using network profiles.

The main thing is to have fabric APs in a site scope (ex: fabric site) and the rest of APs in a different site (any other site).
The WLC will manage both sites (fabric and site X), meaning that it will be the primary controller for these.

1. Your fabric might have a wireless profile already assigned, in that wireless profile, the SSID is marked as fabric SSID.
2. Create a second wireless profile and assign it to site X, there you will configure the SSID as not-fabric/Centralized
3. Provision the WLC and configure it to manage both fabric site and site X.
4. Provision the APs in site X

This way the WLC will maintain a single SSID, create two wireless policies (one for central and one for fabric) and create a policy-tag for the fabric side (matching ssid to fabric policy) and another for non fabric side (matching ssid to central). Binding APs to the corresponding tag.
