Vlan Poll > Domain > AAEP - Policys

AAEPs (attachable access entity profiles) will be consumed by policy-group and define which
encapsulations will be allowed to be used by those policy-groups. One AAEP can be reused
for multiple interfaces; in fact, all ports that serve the same purpose should use the same
AAEP.
