This MIB module provides objects to view the features
and services that are licensed to run on a system (usually
a network entity), and an inventory of the licenses for
these features and services. The inventory of the licenses
is kept in a license pool which is a repository of
the installed licenses.

This MIB does not provide any object to facilitate the 
installation or addition of licenses in the license pool.

The licenses are used to perform specific services, and
are used by, but not limited to, the physical entities. 
The meaningful entities which can use licenses to perform
specific services include: module(9), or chassis(3) as 
defined in RFC 2737.

As an example, some of the services/features that can be 
licensed include (but not limited to) the following :

    - Single Service. Only one of: ATM, FR, or CES
      (Circuit Emulation Service).
    - Multi Service.  More than one of: ATM, FR, or CES. 
    - IMA (Inverse Multiplexing over ATM).
    - MFR (Multilink Frame Relay).
    - Channelization.

As an example of implementation, all licenses can be kept in
the license pool owned by a chassis, while licenseable
services are performed by service modules plugged into that 
chassis. In order to provide licenseable services/features, 
the service modules use/consume appropriate licenses from the 
license pool owned by the chassis.
