I think I did:
(ArubaMaster) #show airgroup active-domains
AirGroup Active-Domains
-----------------------
Domain Name Status
----------- ------
ProdControllers-Airgroup_Domain Excluded
Num active-domains:1
From Running Config:
airgroup domain "ProdControllers-Airgroup_Domain"
ip-address "172.30.0.74"
ip-address "172.30.0.72"
ip-address "172.30.0.71"
ip-address "172.30.0.73"
!
airgroup active-domain "ProdControllers-Airgroup_Domain"
!
In any case, don't I need a domain in a Master-Local topology in order to allow mDNS to traverse local controllers? Wouldn't the local controller recive an mDNS packet from a connected client, then convert to unicast and send to Airgroup clients that the Local controller knows about (but not other local controllers)? Or am I not getting that right?
