Cisco Packet Tracer利用手引き(5)

      Physical Workspace では、ケーブルは物理レイアウトのように編集することができます。

ケーブルは直線ではなく曲げたり、グルーピングしたり、色をつけて判別しやすくしたりできます。

 

ケーブルを曲げるための関節ポイントの作成

ケーブルをクリックして Create Bend Point / Color Cable メニューを選択します。

Create BendPoint を選択すると赤いドットがケーブル上に現れます。 この赤いドットをドラッグして

関節としたい箇所にもっていきます。

 

Cable Length でケーブル間の長さを表現でき、 Total Cable Lengthで2つのデバイス間の長さを調整できます。

 

 

ケーブル上のGroupPointの作成

GroupPoint をケーブルで作るために、ケーブル上にBendPoint がある必要があります。

To create GroupPoints in cables, there must already be BendPoints located in the cables. The process to create a GroupPoint is drag one BendPoint over the top of a second BendPoint. When this is done the Red Dots turn into a single yellow square.

If you create two GroupPoints on a cable and then click between those two GroupPoints, you can create a new GroupPoint. When a GroupPoint is moved all of the cables in the group are moved as if they are a single cable.

Color Coding Cables

To change the color of a cable, click on the cable and then select Color Cable. When the Select Color dialog pops up, select the desired color and then click on the OK button.

Notice that the cable is colored at both ends of the GroupPoints. Cable groups color is always black, it can’t be changed. To reset a color you have selected, follow the same process as assigning a color but click the Cancel button instead of the OK button in the Select Color dialog.

 

Removing GroupPoints and BendPoints

Removing a GroupPoint is actually done as an ungroup. All of the BendPoints that were dragged together to create the group are still on the cables, they just return to the red dots and are now separate again.

To remove the GroupPoint, first click on the Delete tool in the Common Tools Bar or press the Delete key on your keyboard. The Delete tool will now be selected. Point the cursor directly over the GroupPoint that is to be removed (the little circle in the center of the cursor should show the color through it) and click on the GroupPoint. A menu will pop up allowing each individual cable or all cables to be removed from the group.

また、Similation ModeでパケットのQoS スタンプ(Show QoS Stamps on Packets)を表示させたり、ケーブルの長さを表示したり(Enable Cable Length Effects)できます。

Disable Auto Cable オプションで Automatically Choose Connection Typeをケーブルから選択できなくできます。 LoggingボックスでCisco IOSコマンドを入力した履歴をテキストでエクスポートできます。

Administrative パネルでは、Interface tabやMultiuser menu特定のインタフェースにInterface Locking機能を使ってアクセスできないようにします。

マシン上の全ユーザに全体的に設定をするために、 WriteボタンをクリックしてPT.conf ファイルをPacket Tracerインストール場所に保存できます。

オプションとして、User Folderの場所を変更したりパスワードをかけたりできます。

 

 

Hideパネルでは、さまざまなPacket Tracer の機能の表示・非表示ができます。

 

Fontパネルでは、DialogsWorkspace/Activity Wizard, General Interfaceでフォントやサイズの変更が可能です。

Size slider controlでApplication フォントサイズが変更可能です。 Application font で一般のアプリケーションユーザインタフェースのフォントを設定できます。Colors categoryで、Router IOS TextRouter IOS BackgroundPC Console Text,PC Console Background のフォントカラーの変更が可能です。

 

Under the Miscellaneous panel, you can change the assortment of settings. The Simulation – Buffer Full Action feature allows you to set the preferred action that Packet Tracer will perform. You can set the action to Prompt if you want to be prompted when the Simulation buffer is full. At the prompt, you can either Clear Event List or View Previous Events. Alternatively, you can set the action to either Auto Clear Event List to allow Packet Tracer to automatically clear the Event List when the buffer is full or you can set the action to Auto View Previous Events to automatically view the previous events. The Enable Screen Reader Support accessibility feature reads out all the titles and descriptions of the visible window that has the focus. Show Device Dialog Taskbar will enable a taskbar inside the Packet Tracer workspace to navigate between opened device dialog windows. Enable External Network Access from Device Scripts 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. Proxy Settings: 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.

 

Image Cleanup 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 placeholder image File Not Found Image being used in place of the deleted one.

 

Setting a User Profile

You can set your user profile for activity assessment and Multiuser identification. From the Menu Bar, select Options > User Profile to view the User Profile dialog. In the User Profile dialog, you can enter your NameE-Mail, and any Additional Info about yourself that you may want to share.

 

Algorithm Settings

The Algorithms Settings dialog allows the user to make configurations that are otherwise not available in IOS. It also allows tweaking of algorithm settings to make visualization of certain algorithm/protocol behaviors more easily viewable.

CBAC Half-Open Session Multiplier: 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.

TCP Maximum Number of Connections: If the number of connections in SYN-RECEIVED state exceeds this number, any new connections would be rejected.

TCP Maximum Number of Opened Sessions: If the number of connections exceeds this number, any new connections would be rejected.

TCP Maximum Retransmission Timeout in Milliseconds : If a TCP connection does not receive an acknowledgment to a segment it transmitted in this number, it would retransmit the segment.

Switching Storm Control Multiplier: If the bandwidth percentage of broadcast frames used multiplied by this number exceeds the configured threshold, the broadcast frame would be dropped.
