·
item received by the unit that is part of a group
·
ungrouped ICMP packet
· un-handled IP packet
·
broadcast packet
For each item in the tree two extra columns indicate the source and destination IP address. Where
relevant, the port number is appended to the IP address (e.g. for UDP and TCP packets). Some parts of
an IP address are in a special form: any part of an IP address ending on a series of .255 will be displayed
as .all. For example, 192.168.0.255 will be displayed as 192.168.0.all and 192.168.255.255 will be shown
as 192.168.all. Also the IP address 0.0.0.0 is a special case and is displayed as 'none'. In some cases the
source and destination may have the symbols 'R<-' or 'R->' prepended to them. This indicates that a
packet is sent to or from a unit using a different IP number than the IP number the unit has (which the
analyzer assumes to be the IP number used in ARP requests of replies sent by the unit).
16.1.2.3. Details Pane
The middle part of the Protocol View shows the details of the item that is selected in the 'relations' pane.
An example that shows the details of an 'UDP broadcast' item follows:
We will describe the different parts below:
Offset
This box displays the address (offset) of the start of the selected item.
Length
The 'Length' box shows the size of the selected item in bytes.
Num. Trans.
This box shows the number of transactions that corresponds to the selected item. For IP4 this will always
be 1.
