Protocol Settings

This tab is used to manage default protocols and user-defined protocols.

Note that you cannot make any changes to the protocols or create a new one when there is a capture running (You need to stop all captures and go back to the Start Page). In a capture, you can only view the existing protocols.

Protocol List

You can click any of the column headers to rearrange the protocols in descending order or in ascending order.

You can double-click a protocol item to edit it. You are not allowed to modify the color of the pre-specified protocols.

Display Filter

There are two protocol filters on the top for you to locate a certain type of protocol.

• Select protocol: Displays the selected type of protocol in the list and hide the rest, e.g. Ethernet II, IP, TCP and UDP.
• Filter display: Displays the protocols by their status, e.g. All Protocols, built-in Protocols, Customized Protocols and Modified Protocols.

Buttons

• Add: Creates a new rule to identify a new protocol.
• Edit: Edits a highlighted protocol item.
• Delete: Deletes a highlighted protocol item.
• Import: Reads the protocol list from a .cscpro file.
• Export: Saves the protocol list to a .cscpro file.
• Default: Resets the protocol list. All user-defined protocols will be deleted and built-in protocols will be reset. You should be careful of clicking this button.

You cannot delete any built-in protocols and when you are running a capture, the buttons above will be disabled. You need to stop all the captures and go back to the Start Page, and then the buttons will be enabled again.

Adding protocols

To add a protocol, click Add to open the Add Protocol dialog box in which you can specify the protocol name, the alias, and the port number for the protocol. You can add up to forty protocols.

The Add Protocol dialog box appears as below.
