16.1.2.1. Toolbar
At the top of the Protocol View you will find a toolbar with a few buttons:
In front of the name 'Protocol View' a star '*' will be displayed if the protocol analysis settings have been
modified.
Protocol Settings
When clicking this button, the 'Protocol Settings' dialog will be displayed. It shows information used by the
protocol analyzers. It initially shows information that was found automatically and you will be able to
change or add information. See 'IP4-Protocol Settings' below for more information.
Go to next item with warning(s)
When clicking this button, the next item that contains one or more warnings will be selected.
Go to next item with error(s)
When clicking this button, the next item that contains one or more errors will be selected.
Show Transactions and Packets
This button toggles the display of the right pane at the right side of the Protocol View.
Export IP4 packets
Clicking this button will open an export to file dialog that can be used to export all packets found by the
IP4 analyzer. Use this dialog to select the location and name of a file. After pressing OK the packet data
will be written to this file using the LibPCap file format (UNIX standard Library Packet Capture format).
Since there's no option currently in this file format for 1394 packets, the Ethernet format is abused: the
source and destination mac address in the dump are used to hold the specification id's of the 1394 nodes.
An Ethernet mac address is 6 bytes wide, so the first 2 bytes are set to all zeros. The timing information
for each packet is added to a start date of 15 January 1970. Because the file format used is essentially for
Ethernet packets, ARP requests using the 1394 format can't be stored in the file and are ignored.
An export file can be used to further analyze the data using an external application, for example
Wireshark, a free application that can be used to record and view IP4 packets (
www.wireshark.org).
Within Wireshark, select File > Open, and select the exported data file.
Triple Analyzer
For triple Analyzers, the Toolbar looks as follows:
It contains the following additional control:
Analyzer node select control
With this control you are able to select the protocol analysis result of each supported Analyzer node.
16.1.2.2. Relations Pane
This pane shows all transactions and packets found, grouped into items and displayed in a tree. The tree
structure indicates the relation between the items. The items are not necessarily recorded in the same
order as displayed in this tree. However, all items inside the same item of the tree (at the same level) are
listed in the same order as the first corresponding packet of each item was recorded. To find out the order
