Delete a Port Assignment
1. Choose
Set Initial Decoder Parameters

2. Click the
TCP
tab (or
UDP
or
IPX
for those protocols).
3. Select (click on and highlight) the port assignment to delete.

The system deletes the port assignment.
Move a Port Assignment
If you need to move an entry to ensure it is processed before or after another entry, select the entry in the list
and then click the
Move Up
or
Move Down
buttons.
Port Assignment Considerations
l
The analyzer traverses an entry if either the source or destination port match.
l
The analyzer processes port number entries in order from top to bottom.
3.2.4 Determining Master and Slave
In
Bluetooth
, the device that initiates the connection is always the master at connection time. You only need to
know the master and slave at connection time when setting up the I/O Settings. Afterward a role switch may
occur, but the analyzer automatically follows the role switch.
Note:
You do not have to identify a Master address if you are using Firmware Version 62 or
newer.
Role Switches
After the connection has been made, a role switch can take place. A good example of why this happens would be
when a mouse connects to the PC. The mouse initiates the connection, so it is the master. After the connection is
made, a role switch occurs so that the PC becomes the master and the mouse becomes a slave. The role switch
takes place because the PC may be working with multiple devices at the same time, and as such, the PC would not
be a slave of more than one device.
Let us say that a link exists between a PC and a keyboard with the PC a master. If the mouse wants to become a
member of the link it initiates the connection. Since the mouse initiated the connection, it is the master of a new
link and the PC is the slave. The PC is still the master of the link between the PC and keyboard. A role switch now
occurs between the PC and the mouse, and the PC is now the master of a link with two slaves: the mouse and
keyboard.
3.3 Conductive Testing
Conductive testing could be used for many reasons, but the most common use is to isolate the Wi-Fi test setup
from the surrounding environment. Interference from radio frequency (RF) sources is the most common reason
for isolating the test from the environment. This is especially important when the environment contains RF
sources using the industrial, scientific, and medical (ISM) radio bands from 2.4 to 2.485 GHz that are the bands
used for Wi-Fi.
“Conductive” in this context means that you are not “air sniffing”, that is, capturing Wi-Fi transmissions on the
Frontline analyzer's antenna. The conductive test setup uses coaxial cable to directly connect the Device Under
