9800 WLC foreign to AireOS Anchor - WLAN Vlan Assignment

[awatson20]

I have configured a mobility peering between a foreign 9800 controller to an AireOS anchor controller.  The WLAN and policy profile have been created.  Clients connecting to this wlan will receive their IP Address centrally from the anchor controller.  On the 9800 foreign controller, I am not sure what vlan to specify under the policy profile access policy since this is an anchored wlan.  In the old AireOS days, we would specify a bogus vlan and IP address.  What is the config standard for 9800's?  Do we use the WLC management vlan, or specify nothing since this is anchored?

you can create any BLACKHOLE VLAN

Configuration --> Layer 2--> VLAN and use that in profile

       Always validate configurations on the 9800 platform with the CLI command show tech wireless , feed the output into
