DESCRIPTION
|
|
"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.
|
|
|
|
Information provided by this MIB is for CCX related
|
|
features as specified in the CCX specifications.
|
|
|
|
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.
