Location Services

Return to Top

Mechanism by which a device can learn its actual physical (“civic”) location through its connection to a Medianet-ready switch. Upon learning its location, the device can then share this information with peers, management servers, and other equipment on its network. The physical location of a DMP is almost always an important factor in which central management server it should trust, which assets it should play, which commands it should run, and which schedule it should follow.

Someone must configure two essential values on your Medianet-enabled switch: “civic-location-id” and “additional-location-information.” These values are encapsulated into a CDP message that endpoints receive.

civic-location-id

This value describes the physical site — including the municipality, street address, floor designation, and so on — where a switch and its attached nodes are deployed.

additional-location-information

This value describes any additional details to inject into the encapsulated CDP message. As this is a data injection, it depends wholly on the presence of a defined civic-location-idvalue. Absent that value, there is no way for this value to reach any endpoint. Later, when you plug a Medianet-ready DMP into a properly configured switch, the Location Services feature of MSI populates the Location URL field automatically in DMPDM.

Note	CDP and LLDP constrain how much location information you can store on a Medianet-enabled switch. Make
	sure that this information never exceeds 255 bytes.
Note	A DMP 4400G cannot receive or use Location Services information over Wi-Fi. Its connection type to your
	Medianet-enabled switch must be Ethernet.

Medianet	End-to-end intelligent architecture for optimized delivery of rich media to a variety of endpoints
	throughout an enterprise. Cisco Medianet is media-aware, endpoint-aware, and network-aware.
MSI	Media Services Interface. Announces services to a DMP or any other Medianet-ready device that you
	connect to a Medianet-enabled switch. MSI tells devices about their neighbors and their civic location.

•Devices send encrypted registration requests to management servers.

•Servers receive such requests, respond to them, and store records in a local database.
