This read-create INTEGER (closed, open, or unknown) specifies the reachability status of an IP protocol or port advertised in the connection capability table. Client devices use it to decide, before connecting, whether an application they need (such as VoIP over a particular port) will actually work on this network. For example, a venue that blocks outbound SIP traffic would set cLHotspotConnectionCapabilityStatus to closed for the corresponding port entry so VoIP-dependent clients know not to expect that service.
