CISCO-IETF-DOT11-QOS-MIB
AI MIB Summary
The CISCO-IETF-DOT11-QOS-MIB enables monitoring and configuration of IEEE 802.11e Quality of Service parameters on Cisco wireless LAN access points and stations, specifically tracking Arbitration Interframe Space (AIFS), Contention Window (CW) persistence factors, and traffic category priorities to manage medium access control and frame transmission scheduling.
This MIB module provides network management support for QoS on wireless LAN devices. All objects defined in this MIB are listed (object names have been modified to adopt Cisco MIB object naming convention) in the IEEE 802.11E November 2001 draft. The original names of the objects in the standard are included in the REFERENCE clauses. The standard is still under development. The standard IEEE 802.11E MIB can replace some of the MIB objects in this MIB once the standard is finalized.
GLOSSARY and ACRONYMS
Access point (AP) Transmitter/receiver (transceiver) device that commonly connects and transports data between a wireless network and a wired network.
AIFS Arbitration Interframe Space. It is one of the five different IFSs defined to provide priority levels for access to the wireless media. It shall be used by QSTAs to transmit data type frames (MPDUs) and management type frames (MMPDUs).
BSS IEEE 802.11 Basic Service Set (Radio Cell). The BSS of an AP comprises of the stations directly associating with the AP.
CW Contention Window. It is the time period between radio signal collisions caused by simultaneous broadcast from multiple wireless stations. The contention window is used to compute the random backoff of the radio broadcast. The IEEE
802.11b does not specify the unit for the time
period.
CWP Factor Contention Window Persistence Factor. It indicates the factor used in computing new CW values on every 15 unsuccessful attempt to transmit an MPDU or an MMPDU of a traffic category. It is a scaling factor in units of 1/16 ths.
IFS Inter-Frame Space is the time interval between frames. A STA shall determine that the medium is idle through the use of the carrier sense function for the interval specified. In other words, the size of the IFS determines the length of the backoff time interval of a device to the medium. In this case, the medium is the radio wave spectrum. The IEEE 802.11b standard does not specify any unit for the time interval.
BSS IEEE 802.11 Basic Service Set (Radio Cell). The MAC Medium Access Control. Layer 2 in the network model.
MPDU MAC protocol data unit. The unit of data exchanged between two peer MAC entities using the services of the physical layer (PHY).
MMPDU Management type MAC protocol data unit.
MSDU MAC service data unit. Information that is delivered as a unit between MAC service access points.
QBSS Quality of service basic service set.
QSTA QoS station.
STA (WSTA) A non-AP IEEE 802.11 wireless station.

between priority 3 and priority 2. The resulting
default ordering is {7,6,5,4,3,0,2,1}. The default
