The Protected Frame field is 1 bit in length. The Protected Frame field is set to 1 if the Frame Body field contains information that has been processed by a cryptographic encapsulation algorithm. The Protected Frame field is set to 1 only within data frames and within management frames of subtype Authentication, and individually addressed robust management frames. The Protected Frame field is set to 0 in all other frames. When the Protected Frame field is equal to 1, the Frame Body field is protected utilizing the cryptographic encapsulation algorithm and expanded as defined in Clause 11. The Protected Frame field is set to 0 in Data frames of subtype Null Function, CF-ACK (no data), CF-Poll (no data), CF-ACK+CF-Poll (no data), QoS Null (no data), QoS CF-Poll (no data), and QoS CF-ACK+CF-Poll (no data) (see, for example, 126.96.36.199 and 188.8.131.52 that show that the frame body needs to be 1 octet or longer to apply the encapsulation).
The More Data field is 1 bit in length and is used to indicate to a STA in PS mode that more BUs are buffered for that STA at the AP. The More Data field is valid in individually addressed data or management type frames transmitted by an AP to a STA in PS mode. A value of 1 indicates that at least one additional buffered BU is present for the same STA.
The More Data field is optionally set to 1 in individually addressed data type frames transmitted by a CF- Pollable STA to the PC in response to a CF-Poll to indicate that the STA has at least one additional buffered MSDU available for transmission in response to a subsequent CF-Poll.
For a STA with TDLS peer PSM enabled and the More Data Ack subfield equal to 1 in the QoS Capability element of its transmitted TDLS Setup Request frame or TDLS Setup Response frame, a TDLS peer STA optionally sets the More Data field to 1 in ACK frames to this STA to indicate that it has a pending transmission for the STA.
The More Data field is 1 in individually addressed frames transmitted by a mesh STA to a peer mesh STA that is either in light sleep mode or in deep sleep mode for the corresponding mesh peering, when additional BUs remain to be transmitted to this peer mesh STA.
The More Data field is set to 1 in group addressed frames transmitted by the AP when additional group addressed bufferable units (BUs) remain to be transmitted by the AP during this beacon interval. The More Data field is set to 0 in group addressed frames transmitted by the AP when no more group addressed BUs remain to be transmitted by the AP during this beacon interval and in all group addressed frames transmitted by non-AP STAs.
The More Data field is 1 in group addressed frames transmitted by a mesh STA when additional group addressed BUs remain to be transmitted. The More Data field is 0 in group addressed frames transmitted by a mesh STA when no more group addressed BUs remain to be transmitted.
A value of 0 in group addressed frames, in management frames transmitted to nonpeer STAs, and in Probe Response frames indicates that the mesh STA will be in active mode towards all neighbor mesh STAs. A value of 1 in group addressed frames, in management frames transmitted to nonpeer STAs, and in Probe Response frames indicates that the mesh STA will be in deep sleep mode towards all nonpeer mesh power STAs.
A value of 0 in individually addressed frames transmitted to a peer mesh STA indicates that the mesh STA will be in active mode towards this peer mesh STA A value of 1 in individually addressed frames transmitted to a peer mesh STA, except Probe Response frames, indicates that the mesh STA will be in either light sleep mode or deep sleep mode towards this peer mesh STA. When the QoS Control field is present in the frame, the Mesh Power Save Level subfield in the QoS Control field indicates whether the mesh STA will be in light sleep mode or in deep sleep mode for the recipient mesh STA as specified in 184.108.40.206.11.
(e) This is not a Re-Transmission - This field is used to indicate if a frame is a retransmission. This flag is probably the most viewed flag in the mac header. Many things can cause a frame to be retransmitted. High retransmission rates cause poor WiFi performance.
The Duration/ID field is 16 bits in length. The contents of this field vary with frame type and subtype, with whether the frame is transmitted during the CFP, and with the QoS capabilities of the sending STA. The contents of the field are defined as follows:
There are four address fields in the MAC frame format. These fields are used to indicate the basic service set identifier (BSSID), source address (SA), destination address (DA), transmitting STA address (TA), and receiving STA address (RA). Certain frames may not contain some of the address fields.
The SA field contains an IEEE MAC individual address that identifies the MAC entity from which the transfer of the MSDU (or fragment thereof) or A-MSDU, as defined in 220.127.116.11, contained in the frame body field was initiated. The individual/group bit is always transmitted as a 0 in the source address.
The TA field contains an IEEE MAC individual address that identifies the STA that has transmitted, onto the WM, the MPDU contained in the frame body field. The Individual/Group bit is always transmitted as a 0 in the transmitter address.
The Sequence Number field is a 12-bit field indicating the sequence number of an MSDU, A-MSDU, or MMPDU. Each MSDU, A-MSDU, or MMPDU transmitted by a STA is assigned a sequence number. Sequence numbers are not assigned to control frames, as the Sequence Control field is not present.
The frame header contains information about the where the frame is going, the data rate, cipher suite used to encrypt data frames, and more! It is important to understand each field in the header. The four address fields are source, destination, transmitter, and receiver. The header contents are different for each frame type; the image below shows that some fields may be 0 bytes when not in use or X bytes. For example, the header of an acknowledgement (ACK) frame only uses one of four address fields, the receiver address (RA). The other values found in the frame control field of the header that are frequently referenced include:
APs send beacons at a regular interval called the target beacon transmit time (TBTT) to advertise the SSIDs they service. Beacons contain the configuration of the WLAN including whether it supports standards such as 802.11k, 802.11r, the required cipher suites and authentication key management (AKM) methods, whether protection mechanisms are required, etc. The presence of certain information elements (IE) indicate whether the related configuration is present. The figure below shows which fields are mandatory in a beacon frame. Note that this information is in the body of the management frame.
Action frames are management frames that trigger an action to happen. The list of management frame subtypes had become exhausted, so instead of creating new management frames as new technologies required them, the action frame can be used. Action frames do not expect an ACK. They were first introduced in the 802.11h-2003 standard which also introduced transmit power control (TPC) and dynamic frequency selection (DFS). The 802.11-2016 standard includes action frames for many categories such as spectrum management, QoS, HT, VHT, radio measurements, and many more. The table below from 18.104.22.168 of the 802.11-2016 standard shows the spectrum management action frames.
Frame sent by an AP in response to an RTS frame sent by a station. CTS messages are sent at the lowest mandatory data rate, allowing them to reach all stations in the BSS. They only use the receiver address (RA) field in the header. The station in the receiver address field is the one that will be transmitting frames.
ACK frames create a delivery verification method; they are expected after the transmission of data frames to confirm receipt of the frame. If the CRC check fails, the receiver will not send an ACK. If the sender does not receive an ACK, it will retransmit the frame.
This is caused by each of the listed Edge models using the Intel Ethernet Controller i350, which has a limitation that when autonegotiation is not used on both sides of the link, it is not able to dynamically detect the appropriate wires to transmit and receive on (auto-MDIX). If both sides of the connection are transmitting and receiving on the same wires, the link will not be detected. If the peer side also does not support auto-MDIX without autonegotiation, and the link does not come up with a straight cable, then a crossover Ethernet cable will be needed to bring the link up.
The issue is the result of a misconfiguration of the Wi-Fi access point MAC address being set to a value called 'selfMacAddress' and the access point IP address being always configured for 22.214.171.124 in the ENI page. The fix will derive the MAC address from the Wi-Fi interface wlan0, and the analytics interface's IP address.
If a VMware SD-WAN Edge detects loss for the traffic received from the Gateway, it sends a negative-acknowledgement (NACK) message to the Gateway to retransmit the lost packets. The Gateway checks the retransmission slots to retransmit the packets. Ideally the Gateway should stop retransmission once all the slots are checked, but the Gateway checks the retransmission slots repeatedly until it reaches the sequence number in the NACK message, and this can cause the monitor thread in the Gateway to detect this as a hung thread and restart the gateway.
As the result the bursts of packet will be transmitted with specificdelays between the packets within the burst and specific delay betweenthe bursts. The rte_eth_read_clock() must be supported by the device(s)and is supposed to be engaged to get the current device clock valueand provide the reference for the timestamps. If there is no supportedrte_eth_read_clock() there will be no send scheduling provided on the port. 2b1af7f3a8
