Packet Sources

Home > Reference > Dialogs > Settings Dialog > Packet Sources

The Packet Sources page is part of the Settings dialog for capture filters. It is not present in the corresponding dialog for view filters.

The Packet Sources list contains all active network interface cards found on the system. The left column contains the MAC address of each card, the right column gives a short description. If more than one NIC is installed, you can choose from which cards to collect packets by checking or unchecking the entries. At least one entry must be checked. You can distinguish the packet sources of the collected packets in the Packet List View by means of the text color of the Time/Length information. The color can be changed in the Packet Source View.

The Info text box displays additional information for each network interface card in the list above.

The Buffer Settings edit box allows to change the buffer size of the packet store. If you open this page for an existing document, this box will be read only.

Please notice that you set the net size of the buffer. The actual demand of memory will be about 50% higher. This is due to internal memory management and address cache requirements.

Therefore the sum of the buffer sizes of all open documents should not exceed about one third to one half of your system's memory.
