This table is used to initiate linktests between
an AP and one of its associated clients.  CCX 
linktests are done on clients that support CCX.  For
all non-CCX clients, ping test is done.  Note that
ping test is also done when the CCX linktests fail.
                   
With CCX LinkTest support, the controller can test
the link quality in downstream (direction of
traffic from AP to client) direction by issuing 
LinkTest requests towards the client and let client 
record in the response packet the RF parameters 
like received signal strength, signal-to-noise
etc., of the received request packet. 
          
With ping test only those RF parameters that are
seen by the AP are measured.
          
User initiates one run of linktest by adding a
row to this table through explicit management 
action from the network manager.  A row is created
by specifying cLLtClientLtIndex,
cLLtClientLtMacAddress and setting the RowStatus
object to 'createAndGo'.  This indicates the
the request made to start the linktest on the
client identified by cLLtClientLtMacAddress.
cLLtClientLtIndex identifies the particular
instance of the test.  
          
The added row is deleted by setting the corresponding
instance of the RowStatus object to 'destroy'.  In
case if the agent finds that the time duration
represented by cLLtTestPurgeTime has elapsed since
the completion of the linktest, it proceeds to
delete the row automatically, if the row exists at
that point of time.
          
The results of the linktest identified by
cLLtClientLtIndex can be obtained from the
queries to cLLtClientLtResultsTable.

cLLtClientLinkTestEntry row .1.3.6.1.4.1.9.9.516.1.2.1.1

Each entry in this table represents one instance
of the linktest initiated by the user through
a network manager.

cLLtClientLtIndex

Column Syntax OID

cLLtClientLtIndex

This object uniquely identifies one particular
run of the linktest initiated between the client
identified by cLLtClientLtMacAddress and the AP it
is currently associated with.

Constraints:
range: 1-32

.1.3.6.1.4.1.9.9.516.1.2.1.1.1

cLLtClientLtMacAddress

This object represents the mac address of the client
involved in the particular run of linktest. This
object must be set to a valid value when setting
cLLtClientRowStatus to 'createAndGo' to initiate a
run of linktest.

Description:

Represents an 802 MAC address represented in the
`canonical' order defined by IEEE 802.1a, i.e., as if it
were transmitted least significant bit first, even though
802.5 (in contrast to other 802.x protocols) requires M…

cLLtClientLtRowStatus

This object is the status column used for creating
and deleting instances of the columnar objects in
this table.

SNMPv2-TCRowStatusr/w

Type Values:

1	active
2	notInService

4	createAndGo
5	createAndWait
6	destroy

Description:

The RowStatus textual convention is used to manage the
creation and deletion of conceptual rows, and is used as the
value of the SYNTAX clause for the status column of a
conceptual row (as described in Section 7.7.1 of …

This table populates the results of the linktests
initiated by the user through the 
cLLtClientLinkTestTable.  
          
This table has a sparse dependent relationship
with cLLtClientLinkTestTable.  There exists a
row in this table corresponding to the row for 
each row in cLLtClientLinkTestTable identified
by cLLtClientLtIndex.  A row is added to this
table when user, through the network manager, adds
a row to cLLtClientLinkTestTable and initiates
one run of linktest.  A row is deleted by the agent
when the corresponding row of cLLtClientLinkTestTable
is deleted.
          
The manager is expected to poll cLLtClientLtStatus
to check the status of the linktest.  Depending
on the status read through this object
cLLtClientLtStatus, the appropriate columns for
CCX or ping tests are read and linktest statistics
are gathered.

cLLtClientLTResultsEntry row .1.3.6.1.4.1.9.9.516.1.2.2.1
