This MIB is used for managing location information
of end point devices(Telepresence, IP Camera, Digital media 
player etc) connected to switches/routers.

This location information is then carried from the switch/router
to the end point via Cisco Discovery protocol (CDP) or 
Link Layer Discovery protocol (LLDP).

The location information can be used by applications such as 
Cisco Video Surveillance Manager, digital media manager.

Civic location information as described in RFC 4676, identifies
the exact location information like state, city, building, 
floor that helps identify the exact location of the devices.

Definitions:
============
LocationTarget: This is identified by a target type 
(interface, IP session) and target identifier 
(ifIndex, IP address). 

MIB Table Overview:
===================
This MIB consists of five tables:

   1) cdlLocationTable
   2) cdlCivicAddrLocationTable
   3) cdlCustomLocationTable
   4) cdlGeoLocationTable
   5) cdlLocationPreferWeightTable

The cdlLocationTable provides information about 
location information of LocationTarget.

cdlCivicAddrLocationTable provides the 
details about the civic address types like state, 
county, city for a given LocationTarget.

cdlCustomLocationTable provides the ability to
associate arbitrary name/value pairs with a
LocationTarget.  This allows for specification of
information which is not currently included into the
standard definition of Civic address types.

cdlGeoLocationTable provides Geolocation (GPS)
coordinate information for a LocationType.

cdlLocationPreferWeightTable provides information about,
and a method for configuring, the order in which
the system makes use of location information which is
provided by different sources.

The following provides a sample view of 
the contents of the table and the relationship 
between them.
