CISCO-LICENSE-MIB Table View

This table keeps track of the license installation history.
Each time licenses are installed, a record is made in one of
the entries in this table.
          
When licensed features are applicable to physical entities, 
this table contains entries showing various licenseable 
vendor-specific hardware entities represented by the object
celLicenseEntityVendorType, the corresponding license
serial numbers (if any), and license update time-stamp, and 
license update sequence numbers.
          
When licensed features are not applicable to a physical 
entity, the object celLicenseEntityVendorType is set to NULL.
          
Each time a new entry is made in this table, the total
number of installed licenses is updated in the table 
celPoolLicenseTable in the appropriate entry. If the 
necessary entry in the table celPoolLicenseTable does not 
exist, it is created.
          
The implementations may choose to implement the table in 
circular fashion by limiting the number of entries in the 
table. In this case the oldest entry is overwritten by the
latest. The object celLicenseConfigHistoryIndex always
increase monotonically and indicates how many times the
licenses have been installed.

For each entry in the table celLicenseConfigHistoryTable,
this table expands the information showing the installed type 
of license, and the number of licenses. There may be more
than one entries corresponding to a single entry in the table
celLicenseConfigHistoryTable
          
One of the indicies of this table is celLicenseConfigIndex 
which is the index into the table celLicenseConfigHistoryTable.

This table contains the inventory of installed licenses and 
completely defines the license pool owned by the SNMP agent 
implementing this table.
          
These licenses can be used by the appropriate entities
(physical or otherwise) to which these licenses are applicable.

This table contains entries showing the entities (physical
or otherwise) that are using up licenses, and the number 
and type of licenses in use.
          
For example, if a service module is consuming certain type
of licenses from the license pool, an entry corresponding to 
that module will exist in this table and will show the number
and type licenses being used.
          
An entry in this table is automatically created as soon
as an appropriate entity starts using one or more 
licenses of the type celInUseLicenseType.
          
The object celInUseLicenses can increase or decrease any 
time the number of in-use licenses changes. As soon as the 
value of the object celInUseLicenses reduces to the 
value 0, the corresponding entry is deleted automatically.

This table contains entries for those physical entities into
which licenses have been physically programmed. Depending 
upon the implementation, this may involve programming the 
licenses into the non-volatile ram (NVRAM) of a physical
entity, such as a service module. 
          
An entry in this table is automatically created for those 
entities which contain such licenses. This table exists 
independently of all previous tables described in this MIB.
          
The following example illustrates the use of this table for
a specific implementation:
          
For a module, if the object celPhysicallyProgLicenseStatus has
the value 'hasInstallableLic', it means that this module has 
never had its programmed licenses installed (or transferred)
into any chassis, and therefore its license can be installed
(or transferred) if needed. If installation (or transferring)
of licenses (programmed on the entity) takes place, it
results in incrementing the number of licenses in the 
license pool (object celPoolLicensesInstalled) for the 
vendor-specific hardware type corresponding to this module.
Once the licenses from the module have been installed (or
transferred) into the chassis, the value of the object 
celPhysicallyProgLicenseStatus changes to 'alreadyInstalled'.
This prevents any re-installation or re-use of licenses. This
example shows the usage of the module as a vehicle for 
installing (or transporting) licenses into the license pool.
