This object models an 802.11 wireless radio on a device (a stackable interface object as described in {{bibref|TR-181i2|Section 4.2}}). If the device can establish more than one connection simultaneously (e.g. a dual radio device), a separate {{object}} instance MUST be used for each physical radio of the device.

This parameter is based on ''dot11MultipleRetryCount'' from {{bibref|802.11-2012}}. This object contains parameters related to WiFi QoS for different 802.11e access categories (priorities). Access categories are: BE, BK, VI, and VO. These parameters can help control and monitor 802.11e Enhanced distributed channel access (EDCA). The size of this table is fixed, with four entries which are identified by the {{param|AccessCategory}} parameter as follows: * BE (Best Effort) * BK (Background) * VI (Video) * VO (Voice) This identifies the access category. Arbitration Inter Frame Spacing (Number). This is the number of time slots in the arbitration interframe space. {{deprecated|2.15|because it is superseded by the WMM Specification}} {{obsoleted|2.17}} {{deleted|2.18}} Exponent of Contention Window (Minimum). This encodes the values of CWMin as an exponent: CWMin = 2^ECWMin^ - 1. For example, if ECWMin is 8, then CWMin is 2^8^ - 1, or 255, (expressed in {{units}}). {{deprecated|2.15|because it is superseded by the WMM Specification}} {{obsoleted|2.17}} {{deleted|2.18}} Exponent of Contention Window (Maximum). This encodes the values of CWMax as an exponent: CWMax = 2^ECWMax^ - 1. For example, if ECWMax is 8, then CWMax is 2^8^ - 1, or 255, (expressed in {{units}}). {{deprecated|2.15|because it is superseded by the WMM Specification}} {{obsoleted|2.17}} {{deleted|2.18}} Maximum transmit opportunity, in multiples of {{units}}. A TXOP time interval of 0 means it is limited to a single MAC protocol data unit (MPDU). {{deprecated|2.15|because it is superseded by the WMM Specification}} {{obsoleted|2.17}} {{deleted|2.18}} Ack Policy, where False="Do Not Acknowledge" and True="Acknowledge" {{list}} Definition of the histogram intervals for counting the transmit queue length in packets. Each value indicates the maximum value of the interval. For example, "0,1,4,8," defines the five intervals: 0 packets in queue, 1 packet in queue, 2 to 4 packets in queue, 5 to 8 packets in queue, and 9 or more packets in queue. (No value after the last comma means no upper bound.) If this parameter is set to {{empty}}, no {{param|Stats.OutQLenHistogram}} stats will be collected. The time between recording samples of the current transmit queue in {{units}}. This object contains statistics for different 802.11e access categories (priorities). Packet counters here count 802.11 WiFi frames. If there are not separate stats for each access category, (e.g., 802.11e is not used and there is only one queue), then only access category 0 = BE applies (e.g., the statistics for the single queue are in access category 0 = BE). The CPE MUST reset the Access Point's Stats parameters (unless otherwise stated in individual object or parameter descriptions) either when the Access Point becomes operationally down due to a previous administrative down (i.e. the Access Point's Status parameter transitions to a Disabled state) or when the Access Point becomes administratively up (i.e. the Access Point's Enable parameter transitions from false to true). Administrative and operational status is discussed in {{bibref|TR-181i2|Section 4.2.2}}. The total number of {{units}} transmitted in this access category, including framing characters. The total number of {{units}} received in this access category, including framing characters. The total number of {{units}} transmitted in this access category. The total number of {{units}} received in this access category. The total number of outbound {{units}} in this access category that could not be transmitted because of errors. These might be due to the number of retransmissions exceeding the retry limit, or from other causes. The total number of inbound {{units}} in this access category that contained errors preventing them from being delivered to a higher-layer protocol. The total number of outbound {{units}} in this access category which were chosen to be discarded even though no errors had been detected to prevent their being transmitted. One possible reason for discarding such a packet could be to free up buffer space. The total number of inbound {{units}} in this access category which were chosen to be discarded even though no errors had been detected to prevent their being delivered. One possible reason for discarding such a packet could be to free up buffer space. The total number of transmitted {{units}} in this access category which were retransmissions. Two retransmissions of the same packet results in this counter incrementing by two. {{list}} Histogram of the total length of the transmit queue of this access category in packets (1 packet, 2 packets, etc.) according to the intervals defined by {{param|#.OutQLenHistogramIntervals}}, with samples taken each {{param|#.OutQLenHistogramSampleInterval}}. Example: "12,5,1,0,2,0,0,1". This object contains the parameters related to RADIUS accounting functionality for the access point. Enables or disables accounting functionality for the access point. The IP Address of the RADIUS accounting server. The IP Address of a secondary RADIUS accounting server. The client can forward requests to the secondary server in the event that the primary server is down or unreachable, or after a number of tries to the primary server fail, or in a round-robin fashion. {{bibref|RFC2866}} The port number of the RADIUS server used for accounting. The default port is 1813 as defined in {{bibref|RFC2866}}. The port number of the secondary RADIUS server used for accounting. The default port is 1813 as defined in {{bibref|RFC2866}}. If this parameter is not implemented, the secondary RADIUS server will use the same port number as the primary RADIUS server. The secret used for handshaking with the RADIUS accounting server {{bibref|RFC2865}}. The secret used for handshaking with the secondary RADIUS accounting server {{bibref|RFC2865}}. If this parameter is not implemented, the secondary RADIUS server will use the same secret as the primary RADIUS server. Specifies the default interim accounting interval in {{units}}, which is used for service accounting when the ''Acct-Interim-Interval'' attribute is not configured. {{bibref|RFC2869|Section 2.1}} The value MUST NOT be smaller than 60. The value SHOULD NOT be smaller than 600, and careful consideration should be given to its impact on network traffic {{bibref|RFC2869|Section 5.16}}. A value of 0 means no interim accounting messages are sent. This object models an 802.11 connection from the perspective of a wireless end point. Each {{object}} entry is associated with a particular {{object|#.SSID}} interface instance via the {{param|SSIDReference}} parameter, and an associated active {{object|Profile}} instance via the {{param|ProfileReference}} parameter. The active profile is responsible for specifying the actual SSID and security settings used by the end point. For enabled table entries, if {{param|SSIDReference}} or {{param|ProfileReference}} is not a valid reference then the table entry is inoperable and the CPE MUST set {{param|Status}} to {{enum|Error_Misconfigured|Status}}. Note: The {{object}} table includes a unique key parameter that is a strong reference. If a strongly referenced object is deleted, the CPE will set the referencing parameter to {{empty}}. However, doing so under these circumstances might cause the updated {{object}} row to then violate the table's unique key constraint; if this occurs, the CPE MUST set {{param|Status}} to {{enum|Error_Misconfigured|Status}} and disable the offending {{object}} row. Enables or disables this end point. Indicates the status of this end point. {{enum}} The {{enum|Error_Misconfigured}} value indicates that a necessary configuration value is undefined or invalid. The {{enum|Error}} value MAY be used by the CPE to indicate a locally defined error condition. {{reference}} This is the currently active profile, which specifies the SSID and security settings to be used by the end point. {{reference}} {{param}} is determined based on the {{param|Profile.{i}.SSID}} within the associated {{param|ProfileReference}}) endpoint profile. {{param}} MUST be {{empty}} if {{param|ProfileReference}} is {{empty}} (i.e. only when an active profile is assigned can the associated SSID interface be determined). {{numentries}} Throughput statistics for this end point. The data transmit rate in {{units}} that was most recently used for transmission from the access point to the end point device. The data transmit rate in {{units}} that was most recently used for transmission from the end point to the access point device. An indicator of radio signal strength of the downlink from the access point to the end point, measured in {{units}}, as an average of the last 100 packets received from the device. The number of {{units}} that had to be re-transmitted, from the last 100 packets sent to the access point. Multiple re-transmissions of the same packet count as one. This object contains security related parameters that apply to a WiFi end point {{bibref|802.11-2007}}. {{list}} Indicates which security modes this {{object|#}} instance is capable of supporting. EndPoint Profile table. Enables or disables this Profile. When there are multiple WiFi EndPoint Profiles, e.g. each instance supports a different SSID and/or different security configuration, this parameter can be used to control which of the instances are currently enabled. Indicates the status of this Profile. {{enum}} The {{enum|Active}} value is reserved for the instance that is actively connected. The {{enum|Available}} value represents an instance that is not currently active, but is also not disabled or in error. The {{enum|Error}} value MAY be used by the CPE to indicate a locally defined error condition. The profile identifier in use by the connection. The SSID is an identifier that is attached to packets sent over the wireless LAN that functions as an ID for joining a particular radio network (BSS). Location of the profile. This value serves as a reminder from the user, describing the location of the profile. For example: "Home", "Office", "Neighbor House", "Airport", etc. An empty string is also valid. The profile Priority defines one of the criteria used by the End Point to automatically select the "best" AP when several APs with known profiles are simultaneously available for association. In this situation, the End Point has to select the AP with the higher priority in its profile. If there are several APs with the same priority, providing different SSID or the same SSID, then the wireless end point has to select the APs according to other criteria like signal quality, SNR, etc. 0 is the highest priority. This object contains security related parameters that apply to a WiFi End Point profile {{bibref|802.11-2007}}. Indicates which security mode is enabled. A WEP key expressed as a hexadecimal string. {{param}} is used only if {{param|ModeEnabled}} is set to {{enum|WEP-64|ModeEnabled}} or {{enum|WEP-128|ModeEnabled}}. A 5 byte {{param}} corresponds to security mode {{enum|WEP-64|ModeEnabled}} and a 13 byte {{param}} corresponds to security mode {{enum|WEP-128|ModeEnabled}}. A literal PreSharedKey (PSK) expressed as a hexadecimal string. {{param}} is only used if {{param|ModeEnabled}} is set to {{enum|WPA-Personal|ModeEnabled}} or {{enum|WPA2-Personal|ModeEnabled}} or {{enum|WPA-WPA2-Personal|ModeEnabled}}. If {{param|KeyPassphrase}} is written, then {{param}} is immediately generated. The Controller SHOULD NOT set both the {{param|KeyPassphrase}} and the {{param}} directly (the result of doing this is undefined). A passphrase from which the {{param|PreSharedKey}} is to be generated, for {{enum|WPA-Personal|ModeEnabled}} or {{enum|WPA2-Personal|ModeEnabled}} or {{enum|WPA-WPA2-Personal|ModeEnabled}} security modes. If {{param}} is written, then {{param|PreSharedKey}} is immediately generated. The Controller SHOULD NOT set both the {{param}} and the {{param|PreSharedKey}} directly (the result of doing this is undefined). The key is generated as specified by WPA, which uses PBKDF2 from PKCS #5: Password-based Cryptography Specification Version 2.0 {{bibref|RFC2898}}. A passphrase for {{enum|WPA3-Personal|ModeEnabled}} or {{enum|WPA3-Personal-Transition|ModeEnabled}} security modes. NOTE: this parameter is for WPA3. WPA2 {{param|PreSharedKey}} is generated from {{param|KeyPassphrase}}. Management Frame Protection configuration applicable when {{param|ModeEnabled}} is set to {{enum|WPA2-Personal|ModeEnabled}}, {{enum|WPA2-Enterprise|ModeEnabled}}, {{enum|WPA3-Personal|ModeEnabled}}, or {{enum|WPA3-Enterprise|ModeEnabled}}. When in WPA3 modes, {{param}} MUST be set to {{enum|Required}}. Enable SAE with group dependant hash usage in WPA3 security modes. This flag enables or disables the use of SAE with group dependant hash instead of simple SAE applicable when {{param|ModeEnabled}} is set to {{enum|WPA3-Personal|ModeEnabled}}, {{enum|WPA3-Personal-Transition|ModeEnabled}}, or {{enum|WPA3-Enterprise|ModeEnabled}}. If {{param}} is set to {{enum|Disabled}}, then only AKM8 shall be used. If it is set to {{enum|Transition}}, then both AKM8 and AKM24 shall be used. Finally, if {{param}} is set to {{enum|Enabled}}, then only AKM24 shall be used. {{enum|Enabled}} is invalid when {{param|ModeEnabled}} is set to {{enum|WPA3-Personal-Transition|ModeEnabled}}.
