Filters
Filters allows gathering statistics according to the programmed filters.
Filters provide the capability to analyze a specific stream’s behavior in
order to monitor a single protocol’s behavior, perform SLA verification, or
precisely troubleshoot unwanted behavior. Up to 10 filters having up to four
operands each can be defined and enabled.
Note: Not available with: eCPRI dual port topology; multiple link interface.
From the test menu, tap Functions, and the Filters tab.
<Port #> button, when available, allows selecting the port to be
displayed. For Dual Port topology both ports are available. For the
Through Mode test application, filters apply only to the Primary Port.
Filter allows the selection of the filter number (1 to 10). The filter
criteria, if defined, will be displayed. A filter used (enabled) for data
capture will not be configurable and the message Filter in use for
data capture is displayed.
Enable check box when selected enables the currently selected filter.
The filter has to be configured first before enabling it. If the filter
configuration contains errors, it will not be possible to enable it. A filter
can be enabled or disabled even when the test is running. It is not
possible to modify or disable a filter that is already in use for capture
until either another filter or Interface (see Capture Source on
page 724) is assigned to capture.
Enabled Time indicates the time during which the filter is enabled.
Assign to Capture assigns the selected filter for packet capture (see
Packet Capture on page 724).
Filter Configuration
The filter configuration section allows configuring the filter criteria for the
selected filter. The configuration is only possible when the Enable check
box is cleared. Refer to Filter Configuration on page 971.
