VLAN Filter Settings

The VLAN Filter Settings page inside the Settings dialog:

The VLAN ID Filter page has almost the same layout as the address filter pages, though it has only a single filter list as data packets always belong to one VLAN. As sender and receiver must be in the same VLAN, there is no need for a source and destination filter.

The VLAN ID list contains all known VLAN IDs. It has three columns as the address filter dialogs, though the Raw and System name for VLAN IDs are currently identical. To edit a description, select a VLAN ID name in the first column, then click it a second time or press F2 or Insert on the keyboard. To accept the changes click outside the edit box or press Enter on the keyboard. To cancel editing press Esc on the keyboard. VLAN IDs are added to the address database automatically while packets are collected or by using the edit box below the list (see 4).

The 'No VLAN' entry is a default name for packets that do not belong to a VLAN (normal LAN packets). You can use this value in the filter to include or exclude the normal network traffic without VLAN ID. If you like, you can change this name as any other VLAN ID name.

You cannot delete VLAN IDs from this list while the application is running. But you can specify whether VLAN ID information will be saved or not when the application is closed. The current state is revealed by the disk icons on the left of the VLAN ID names. A strikethrough disk symbol refers to VLAN ID entries that will be discarded, while entries marked by a dark disk will be saved on disk. To toggle the persistence state, click the disk symbol or press the space bar on the keyboard while one or more entries are selected.

Note: Changes to the VLAN ID descriptions, colors, and persistence states are applied immediately and won't be undone if you click the Cancel button.

These buttons add or remove VLAN IDs to / from the filter list. The right arrow button will add all selected entries from the address list to the filter. To add a single VLAN ID to the list, you can also double-click it. The left arrow button removes all selected entries in the filter list. If none is selected, it will remove all entries from the list. To remove a single VLAN ID from the filter list you can also double-click it.

The Filter list with Include / Exclude selector buttons. If Off is selected, all packets will pass the filter ignoring the contents of the filter address list as if this filter does not exist at all. If the filter list is empty, the filter is implicitly switched off.

If Incl is selected, only packets that belong to a VLAN in the filter list will pass the filter. And if Excl is selected, only packets that do not contain a VLAN ID from the list will pass the filter. Use the 'No VLAN' entry to filter packets that do not belong to a VLAN at all (normal LAN traffic).

This is an edit box to add a new VLAN ID to the address database. Enter a number between 1 and 4095 and click the + button to add it to the list. See also Address Name Formats.

These are a color selector button and an address group combo box. Click the color selector button to open a color selection dialog to change the color of the VLAN ID in the Packet List View and Statistics View. You can choose Default in this dialog to remove the color information from the VLAN ID entry. Use the address group combo box to assign the selected VLAN IDs to an address group. You can create new address groups on the Address Groups page of the Settings dialog.
