As mentioned in the zigbee protocol stack that zigbee MAC layer frame composed of MAC header,MAC payload and FCS. The diagram below depicts generic mac frame format adopted in zigbee technology at MAC layer. This part is also referred as MPDU or MAC Protocol Data Unit. This gets embedded into PPDU(physical PDU) frame of zigbee.

Generic MAC layer frame has frame control field of 2 octets. It carries useful information such as frame type, source and destination addressing modes. Frame type specifies whether the frame is beacon frame,data frame, ACK of data, MAC command frame etc. The same is outlined 'Frame type subfield' table below with 3 bits.

As shown below beacon frame carries frame control field and addressing fields along with sequence number. It is broadcasted to obtain PAN ID of nearby zigbee devices.

Once connection is established data frame carry data. The format of data frame is similar to generic mac frame format and is shown in the table below.

Zigbee protocol supports different command frames for difference use case as mentioned below in the table.
