This is the MAC address of the parent access
point for this device.  The value is zero if this
is a root access point.

An entry represents a currently active device
associated with this device.  These active devices
include: wireless clients, repeaters, and bridges.

Each entry provides association statistics of
various devices interacting with this device on
each of the IEEE 802.11 interfaces.

Each entry is the device specification of a client
of this device on the IEEE 802.11 radio interfaces.
Clients are grouped according to the SSIDs of the
interfaces they use for associations and the MAC
address of their parent devices if the clients are
repeat APs.

Each entry contains statistics about errors,
data transmitting and receiving rates and counts
information of a client.

This is the number of wireless clients
currently associating with this device on this
interface.

This is the number of bridges currently
associating with this device on this interface.

This is the number of repeaters currently
associating with this device on this interface.

This object counts the number of stations
associated with this device on this interface
since device re-started.

This object counts the number of stations
authenticated with this device on this interface
since device re-started.

This object counts the number of stations
roamed from another device to this device on
this interface since device re-started.

This object counts the number of stations
roamed away from this device on this interface
since device re-started.

This object counts the number of stations
deauthenticated with this device on this
interface since device re-started.

This object counts the number of stations
disassociated with this device on this
interface since device re-started.

The MAC address of the client.

The MAC address of the parent of the client if the
client is a repeater AP.  If this client has no parent,
the value is '00000000'h.

The role classification of the client.

The device type of the client.

The radio classification of the client.

When this object is 'true', it indicates that the
WEP key mechanism is used for transmitting frames
of data for this client.  The default value of this
object is 'false'.

When this object is 'true', it indicates that this
client is using WEP key mixing.

When this object is 'true', it indicates that the
MIC is enabled for this client.  The default value of
this object is 'false'.

The power management mode of this client.  The
two possible modes are:
active(1)    - this client is not in power-save
mode and it is actively sending or
receiving data.
powersave(2) - this client is in power-save mode and
it wakes up once a while to check for
pending data.

This is the association identification number of
clients or multicast addresses associating with this
device.  For a multicast address with clients, the
cDot11ClientAid is '0'.  For the uplink association
from this device to its parent access point, the
cDot11ClientAid is always '1'.  For any multicast
address with no client currently known to be
associated with this device, the cDot11ClientAid is
'2008'.

This is the set of data rates at which this client
can transmit and receive data.  Each client can
support up to 126 rates.  Each octet contains an
integer value representing one of these 126 rates.
Each rate shall be within the range from 2 to 127,
corresponding to data rates in increments of 500 kb/s
from 1 Mb/s to 63.5 Mb/s, This value is reported in
transmitted Beacon, Probe Request, Probe Response,
Association Request, Association Response,
Reassociation Request, and Reassociation Response
frames, and is used to determine whether a BSS with
which the client desires to synchronize is suitable.
It is also used when starting a BSS.

This is the Cisco IOS software version if the other
end of the association is a bridge, access point, or
repeater. If it is a wireless client, this is the
firmware version of the client card.

This is the Cisco IOS device hostname if the other
end of the association is a bridge, access point, or
repeater. If it is a wireless client, this is the
configured client name.

This object indicates the state of the authentication
and association process between the two parties:
initial(1)             - association request
received from client,
authenNotAssociated(2) - 802.11 authenticated but
not 802.11 associated,
assocAndAuthenticated(3)  - 802.11 associated and
802.1x authenticated,
assocNotAnuthenticated(4) - 802.11 associated but
802.1x not
authenticated.

This is the IP address type of the
cDot11ClientIpAddress.

This is the static or DHCP assigned IP address of the
client.

This is the set current transmit data rates for
this client.  Each client can transmit data at all
of its configured rates.  There is a maximum of 126
it can configure to transmit.  Each octet contains
an integer value representing one of these 126
rates it is currently transmitting.  Each rate shall
be within the range from 2 to 127, corresponding
to data rates in increments of 500 kb/s from
1 Mb/s to 63.5 Mb/s.  This value is reported in
transmitted Beacon, Probe Request, Probe Response,
Association Request, Association Response,
Reassociation Request, and Reassociation Response
frames.

associated with this device.

This is a device-dependent measure of the signal
strength of the most recently received packet from
this client.  It may be normalized or unnormalized.

This MIB module provides network management
information on IEEE 802.11 wireless device
association management and data packet forwarding
configuration and statistics.  This MIB is an
extension to the IEEE802dot11-MIB and provides
per client based information.
The IEEE802dot11-MIB is defined in the IEEE Std
802.11-Jan 14 1999, Wireless LAN Medium Access
Control and Physical Layer Specifications, by the
LAN MAN Standards Committee of the IEEE Computer
Society.
GLOSSARY and ACRONYMS
Access point (AP)
Transmitter/receiver (transceiver) device
that commonly connects and transports data
between a wireless network and a wired network.
Association
The service used to establish access point
or station mapping and enable STA invocation
of the distribution system serivces.
(Wireless clients attempt to connect to
access points.)
Bridge
Device that connects two or more segments
and reduces traffic by analyzing the
destination address, filtering the frame,
and forwarding the frame to all connected
segments.
Bridge AP
It is an AP that functions as a transparent
bridge between 2 wired LAN segments.
Bridge Host
This is also known as Work Group Bridge.  This
is a non-root bridge that is connected to a
remote LAN segment and will only communicate
with repeaters or root bridges.  It does not
accept association from other wireless devices.
BSS
IEEE 802.11 Basic Service Set (Radio Cell).  The
BSS of an AP comprises of the stations directly
associated with the AP.
Client (Client Station)
A wireless device in a wireless network
associated with an access point.
IEEE 802.11
Standard to encourage interoperability among
wireless networking equipment.
MIC
Message Integrity Check.  A MIC can, optionally,
be added to WEP-encrypted 802.11 frames.
Non-Root Bridge
This wireless bridge does not connect to the main
wired LAN segment.  It connects to a remote wired
LAN segment and can associate to root bridges and
other non-root bridges that accept client
associations.  It also can accept associations
from other non-root bridges, repeater access
points, and client devices.
Repeater
Device that connects multiple segments, listening
to each and repeating signal on one to every other
connected one; regenerates each transmission
so that it can travel farther.
Repeater or Non-root Access Point
The repeater access point is not connected
to the wired LAN.  The Repeater is a wireless
LAN transceiver that transfers data between
a client and another access point, another
repeater, or between two bridges.  The repeater
is placed within radio range of an access point
connected to the wired LAN, another repeater, or
an non-root bridge to extend the range of the
infrastructure.
Root Access Point
This access point connects clients to the main
wired LAN.
Root Wireless Bridge
This wireless bridge is connected to the main
wired LAN.  This wireless bridge can communicate
with non-root wireless bridges, repeater access
points, and client devices but not with another
wireless root bridge.  Only one wireless bridge
in a wireless LAN can be set as the wireless
root bridge.
SSID
Radio Service Set ID.  It is used for identification
during association.
STA (WSTA)
A non-AP 802.11 wireless station.
WEP
Wired Equivalent Privacy.  'WEP' is generally used
to refer to 802.11 encryption.
Work Group Bridges (WGB)
See bridge host.

This is the device association information group.

This is the client configuration information group.
