That configuration would be applied to the e0 port of ALL APs that have this profile in the AP-Group. Note that in your example, you have the "default" profile. Because this is used in ALL AP Groups, changing e0 could have disasterous results on the network.
I would recommend using the "save as" button and then saving everything to a non-default profile that would only be applied to this AP group
A bigger question remains on why you are required to do this? With Aruba, we are a pure overlay on the LAN. You shouldn't need to trunk VLANs to the APs if all user traffic is terminating at the 6000
