CISCO-DOT11-QOS-MIB file content
The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.
Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

The objects defined in this MIB provide equivalent support as the objects in the IEEE 802.11E Standard draft. The original names of the objects in the standard are included in the REFERENCE clauses. 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 class. It is a scaling factor in units of 1/16ths. 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."
