<p> You can customize your Packet Tracer experience by setting your own
preferences. From the <strong>Menu Bar</strong>, select <strong>Options/Cisco Packet Tracer(Mac)</strong>
<strong>Preferences</strong> (or simply press <strong>Ctrl + R/Cmd + R(Mac)</strong>)
to view the program settings.</p>
<p>Under the <strong>Interface</strong> panel, you can toggle the <strong>Animation</strong>,
<strong>Sound</strong>, and <strong>Show Link Lights</strong> settings to
suit the performance of your system and your preferences. You can also
manage information clutter with the <strong>Show Device Labels</strong>,
<strong>Always Show Port Labels</strong>, and <strong>Show Port Labels
When Mouse Over</strong> settings. Also, you can also toggle <strong>Show
QoS Stamps on Packets</strong> shown in Simulation Mode and <strong>Enable
Cable Length Effects</strong>. The <strong>Disable Auto Cable</strong>
option allows you to toggle the Automatic Connection when connecting
devices. The <strong>Show Device Dialog Taskbar</strong> option allows
you to toggle the taskbar that is displayed at the bottom of the workspace
which organizes currently opened device dialogs. The <strong>Logging</strong>
feature allows the program to capture all Cisco IOS commands that you
enter and export them to a text file (refer to the "Configuring Devices"
page for more information). You can also change the base language
of the program by choosing from the <strong>Languages</strong> list and
then pressing the <strong>Change Language</strong> button. Lastly, you can personalize your Packet Tracer appearance by select different color scheme.</p>

<p>Under the <strong>Administrative</strong> panel, you can disable access
to a particular interface such as the <strong>Interface tab </strong>and
the <strong>Multiuser menu</strong> using the <strong>Interface Locking</strong>
feature. <strong>Packet Tracer Skills Assessments</strong> will display to you
the currently associated Cisco Packet Tracer installation used for online Packet
Tracer Skills Assessments (PTSA). If the Register button is enabled, then this
installation is not the default install for the assessments. Use the Register
button to make this installation to be used for online skills assessments.
Administrative privileges may be required, start Cisco Packet Tracer as an
administrator if necessary. In order for the settings and configurations to
apply globally for every user on the machine, you need to click on the
<strong>Write</strong> button to save the PT.conf file to the Packet Tracer
installation folder. Optionally, you may change the <strong>User Folder</strong> to a
different location which is where your own settings, configurations, save
files, and device templates are stored. Additionally, you can set a <strong>Password</strong>
to prevent others from tampering with these preferences. Note that the
password is case-sensitive.</p>

The Auto File Backup Interval controls how often Packet Tracer will backup your
current file. This can be turned off or changed in 5 minute increments. When this
feature is turned on, your existing work will be saved to a new file with the
extension .bak alongside the file that the current work is opened from. If the
current work is not opened from a file, it will save to User Folder with the name
unnamed.bak in the Administrative tab. This feature will overwrite any existing files with the
same name as the backup file, including older backup files, or files that happen
to have the same name. You may notice momentary pauses in Packet Tracer when
an auto backup is happening. Disable this feature if it is interfering with your work.
The <strong>Simulation - Buffer Full Action</strong> feature allows you
to set the preferred action that Packet Tracer will perform. You can set
the action to <strong>Prompt</strong> if you want to be prompted when the
Simulation buffer is full. At the prompt, you can either <strong>Clear
Event List</strong> or <strong>View Previous Events</strong>.
Alternatively, you can set the action to either <strong>Auto Clear Event
List</strong> to allow Packet Tracer to automatically clear the Event
List when the buffer is full or you can set the action to <strong>Auto
View Previous Events</strong> to automatically view the previous events.
<strong>Show Device Dialog Taskbar</strong> will enable a taskbar inside the Packet Tracer workspace to navigate between opened device dialog windows. <strong>Enable External Network Access from Device Scripts</strong> will allow script modules to create and open connections to your physical network. It opens up a new realm of possibility to integrate between real world networks your scripts. <strong>Proxy Settings</strong>: The proxy settings here will apply to all network connections, except the multiuser feature. Select the appropriate setting for your proxy. The default behavior of Packet Tracer will attempt to use your system proxy settings to connect to the network. If the system proxy settings are incorrect, changing the settings here will override any system setting going forward. Make sure to click Apply Proxy to save the configuration.</span>

<p><strong>Image Cleanup</strong> panel shows all custom graphics images
used by current user network. These files usually come from custom device
icons, container backgrounds or custom IoT device graphics. These images
are saved inside user network files. Often times, when a user goes through
several authoring cycles for the same network file, these custom images
accumulate. In this case the panel at hand allows users to view the list
of custom images presently saved in the file and delete those that the
user believes are no longer used for anything in the current network file.
A note of caution needs to be voiced here that once these files are
removed from the file they may not be recoverable, unless there is an
external copy saved outside Packet Tracer. Removing a file that is still
being used by one of the components of the current user network would
result in the <em> placeholder image </em> <img src="images/gFileNotFound.png"
width="3%" alt="File Not Found Image"> being used in place of the deleted one.</p>

<p>CBAC <strong>Half-Open Session Multiplier</strong>: If the number of
half-open CBAC sessions multiplied by this number exceeds the configured
max half-open session count, new sessions would not be opened.</p>
<p>TCP <strong>Maximum Number of Connections</strong>: If the number of
connections in SYN-RECEIVED state exceeds this number, any new connections
would be rejected.</p>
<p>TCP <strong>Maximum Number of Opened Sessions</strong>: If the number of
connections exceeds this number, any new connections would be rejected.</p>
<p>TCP <strong>Maximum Retransmission Timeout in Milliseconds </strong>:
If a TCP connection does not receive an acknowledgment to a segment it
transmitted in this number, it would retransmit the segment.</p>
<p>Switching <strong>Storm Control Multiplier</strong>: If the bandwidth
percentage of broadcast frames used multiplied by this number exceeds the
configured threshold, the broadcast frame would be dropped.</p>
