Location Services
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.
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 DMP4400G cannot receive or use Location Services information over Wi-Fi. Its connection type to your
Medianet-enabled switch must be Ethernet.
Tip Is the Location ID value blank in DMPDM? If so, make sure that a civic-location-id value is defined correctly on your
switch. (CSCti85043).

Medianet
End-to-end intelligent architecture for optimized delivery of rich media to a variety of endpoints
throughout an enterprise. CiscoMedianet 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.
MSI registration
service
Medianet feature by which:
•
Devices send encrypted registration requests to management servers.
•
Servers receive such requests, respond to them, and store records in a local database.
MSI service
discovery
Mechanism that applies DHCP option125 packets to advertise —and poll for— the availability of
particular services in a network. Service discovery also notes which hosts provide these services.
