Decode reassembled PDU
The PDU is the Protocol Data Unit: the payload of a network application packet. When a web page, for example, is sent over the Internet, the page is broken into convenient sized pieces and transmitted in a series of packets. You can attempt to locate all of the other pieces of this page, decode them, and present the results in a single temporary Packet Decode window.
NOTE: Decode reassembled PDU is not supported from a Capture Engine.
To decode and reassemble a PDU:
• Right-click a packet containing one of the fragments of the web page and choose
An attempt is made to locate all of the other pieces of the page and decode them; the results are presented in a single temporary Packet Decode window. The title bar of the window shows a packet number, followed by (Reassembled PDU). The packet number is the packet identified as the one containing the first part of the PDU.
TIP: You can choose to save or print the decode of the individual Packet Decode window containing the reassembled PDU (choose , or from the menu).
NOTE: The Packet Decode window containing the decoded reassembled PDU is temporary. If you close the window without saving, the information is discarded. In any case, creating a reassembled PDU does not change the contents of any of the packets in the capture window.
