This reports the access type of this VLAN group request - for example whether the requesting policy wants read/trunk access versus some other access mode. This distinguishes a request that simply wants to trunk the group's VLANs down to a server from other, more restrictive access modes, which matters when an admin is deciding whether a given template's request will actually deliver full VLAN connectivity or something more limited. A vNIC template that needs to trunk all VLANs in the group would show a read-access type consistent with normal trunking, versus a more restrictive access mode used elsewhere.
