| ciscoLwappDot11ClientTsMIB | 1.3.6.1.4.1.9.9.622 | | | This MIB is intended to be implemented on all those
devices operating as Central controllers, that
terminate the Light Weight Access Point Protocol
tunnel from Cisco Light-weight LWAPP Access Points.
This MIB provides information about troubleshooting 802.11
clients during their association with the controller.
The clients that need to be monitored are added by the
controller to a watchlist. Once added the controller
will start storing the messages related to that client.
These messages are useful to troubleshoot the reasons
for failures during assoication.
The relationship between CC and the LWAPP APs
can be depicted as follows:

The LWAPP tunnel exists between the controller and
the APs. The MNs communicate with the APs through
the protocol defined by the 802.11 standard.
LWAPP APs, upon bootup, discover and join one of the
controllers and the controller pushes the configuration,
that includes the WLAN parameters, to the LWAPP APs.
The APs then encapsulate all the 802.11 frames from
wireless clients inside LWAPP frames and forward
the LWAPP frames to the controller.
GLOSSARY
Access Point ( AP )
An entity that contains an 802.11 medium access
control ( MAC ) and physical layer ( PHY ) interface
and provides access to the distribution services via
the wireless medium for associated clients.
LWAPP APs encapsulate all the 802.11 frames in
LWAPP frames and sends them to the controller to which
it is logically connected.
Central Controller ( CC )
The central entity that terminates the LWAPP protocol
tunnel from the LWAPP APs. Throughout this MIB,
this entity also referred to as 'controller'.
Cisco Compatible eXtensions (CCX)
Wireless LAN Access Points (APs) manufactured by Cisco
Systems have features and capabilities beyond those in
related standards (e.g., IEEE 802.11 suite of
standards, Wi-Fi recommendations by WECA, 802.1X
security suite, etc). A number of features provide
higher performance. For example, Cisco AP transmits a
specific Information Element, which the clients adapt
to for enhanced performance. Similarly, a number of
features are implemented by means of proprietary
Information Elements, which Cisco clients use in
specific ways to carry out tasks above and beyond the
standard. Other examples of feature categories are
roaming and power saving.
Light Weight Access Point Protocol ( LWAPP )
This is a generic protocol that defines the
communication between the Access Points and the
Central Controller.
Mobile Node ( MN )
A roaming 802.11 wireless device in a wireless
network associated with an access point. The terms
'Mobile node' and 'client' are used interchangeably.
Radio Management (RM)
This term refers to managing the 802.11 radio
environment to provide the best quality service to
to the 802.11 wireless clients.
Service Set Identifier ( SSID )
SSID is a unique identifier that APs and clients
use to identify with each other. SSID is a simple
means of access control and is not for security.
The SSID can be any alphanumeric entry up to 32
characters.

informational message or an error message.
This object holds good only if the corresponding
cldctClientInfoLevel object has a value of

| cldctWatchListTable | 1.3.6.1.4.1.9.9.622.1.2.1 | | not-accessible | This table represents the clients which are being monitored by
the controller during association.
The types of clients that can be monitored are CCX, non-CCX
and WGB clients.
Entries are created by explicit management action by the
user.
A row is created by specifying the cldctWatchListModuleList,
cldctWatchListTimeRemaining and cldcClientMacAddress with the
'RowStatus' changed to createAndGo.
This indicates that the request is made to start storing the
the messages on the controller for the client identified by
cldcClientMacAddress.
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 cldctWatchListTimeRemaining has elapsed since
the addtion of the client to the watchlist, it proceeds to
delete the row automatically, if the row exists at that point
of time.
The messages stored on the controller can be obtained
from cldctClientInfoTable. |
