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.
AES
Advanced Encryption Standard
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.
CCX
Cisco Compatible eXtensions
A set of specifications which when implemented
would make a client radio interoperable with a
Cisco WLAN infrastructure and make best use of the
innovations for enhanced security, mobility,
quality of service and network management.
CCMP
Code Mode/CBC Mac Protocol
Client (Client Station)
A wireless device in a wireless network
associated with an access point.
Direct Sequence Spread Sprectrum ( DSSS )
DSSS is a method to send data where the
transmitting and receiving systems operate at
frequencies as wide as 22MHz. The wide channels
help the participating systems to send more
information at higher data rates than the FSSS
systems.
EAP
Extensible Authentication Protocol
EAP-TLS
Extensible Authentication Protocol-Transport
Layer Security
Frequency Hopping Spread Spectrum ( FSSS )
FSSS systems hop from one frequency to another in
the allowed band of frequencies during the data
transmission. 83 MHz is specified as the allowed
band of frequencies in the 2.4 GHz spectrum.
IEEE 802.11
Standard to encourage interoperability among
wireless networking equipment.
IEEE 802.11b
The IEEE 802.11b standard describes DSSS systems
that operate in the 2.4 GHz ISM band at data
rates of 1, 2, 5,5 and 11 Mbps.
IEEE 802.11a
The IEEE 802.11a standard describes wireless LAN
operation in the 5 GHz UNII band at data rates
of 6, 9, 12, 18, 24, 36, 48 and 54 Mbps.
IEEE 802.11g
This standard specifies operation in 2.4 GHz ISM
band at data rates of 6, 9, 12, 18. 24, 36, 48 and
54 Mbps.
Industrial, Scientific and Medical band (ISM)
A license-free band specified by the Federal
Communications Commission for use by the wireless
LAN systems. The ISM bands are located starting
at 902 MHz, 2.4GHz and 5.8 GHz.
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.
PCI
Peripheral Component Interconnect
A local bus standard developed by Intel
Corporation. Most modern PCs include a PCI bus.
PCI is a 64-bit bus, though it is usually
implemented as a 32-bit bus. It can run at clock
speeds of 33 or 66 MHz. At 32 bits and 33 MHz, it
yields a throughput rate of 133 MBps.
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.
TKIP
WPA Temporal Key encryption.
Unlicensed National Information Infrastucture (UNII)
The UNII bands are in the 5 GHz range and are 100
MHz wide. These bands are used by 802.11a-compliant
devices.
WEP
Wired Equivalent Privacy. 'WEP' is generally used
to refer to 802.11 encryption.
WPA
WiFi Protected Access
Work Group Bridges (WGB)
See bridge host.
