NIC of a monitoring device, random packet loss may occur, depending on
utilization levels of the tapped links. Random packet loss may lead to
inconsistent network monitoring results. Traffic from monitoring devices can
be routed back to Network Ports in some cases (for example, if TCP reset
commands are sent). In this case, the Network Port > Monitor Port traffic
takes precedence over the Monitor Port > Network Port traffic.
7.2.5 Filter Configuration
The Filter Configuration element of FLOW control ™ provides the user with the
ability to view and apply filters to the various hardware filters available in one
of the filtered products.
The screen is split into two sections.
On the left side is a list of the filters configured in the Filter Management
element of FLOW
control ™. The filters are grouped by type. PASS-ALL and
PASS-NONE filters are always available, even if no other filters have been
created in the Filter Management element of FLOW control ™.
On the right side, the specific hardware filters that can be configured are listed
by port.
In order to apply a defined filter to a port specific filter, select the filter to which
the definition is to be applied, then double click on the port name in the left
hand pane of the Filter Configuration screen. Alternatively, selection of said port
filters in the right hand pane can be made, then the filter selected in the left
hand pane and the
Apply button pressed.
The Readback button performs an inquiry from the connected hardware and
displays the names of the filters that are currently applied to a given port's
filters.
