Filter default name is the system assigned name for a filter entry. These names are displayed in various locations in the NTO Control Panel, including in bold letters on the diagram view. The default name for dynamic filters is assigned by the system when the filter is created. A dynamic filter's default name begins with the letter 'F' followed by the first unused number starting with 1. The first dynamic filter created in the system is F1, followed by F2. If F1 is deleted the next dynamic filter that is created will have default name F1. The default name for port filters is platform dependent. All licensed ports are assigned a default name which corresponds to the default port name displayed in the NTO Control Panel. Port filters which are members of bidirectional port groups will have two filter rows with the same default name - one for the network port filter and one for the tool port filter. For port filters, the value of anueFilterDefaultName maps to the ifMIB ifXTable ifName field. The default name for port group filters is assigned by the system when the port group is created. A Port group's default name begins with the letters 'PG' followed by the first unused number starting with 1. The first port group created in the system is PG1, followed by PG2. If PG1 is deleted the next port group that is created will have default name PG1. Port group filters which are configured as bidirectional will have two filter rows with the same default name - one for the network port group filter and one for the tool port group filter. For port group filters, the value of anueFilterDefaultName maps to the ifMIB ifXTable ifName field.
