Overview 13


3 Overview

VS-2024-F — Data Filtering — Instead of tools attempting to keep up with high-speedaggregated traffic streams, the VS-2024-F (with data filtering) provides the option of applying filtersto the data to increase tool efficiency and eliminate port over subscription. Line-rate hardwarefiltering on each port allows you to customize and streamline the amount and type of data eachconnected monitoring tool receives. Because they are receiving only traffic of interest, tools runfaster, data is easier to work with, and issues are resolved quicker. Filters include IP and MACranges, VLAN, frame, port number, protocol type, even customizable offsets in the packet header.

Reliable and Easy to Use — Every unit comes with dual redundant power supplies to ensuremonitoring uptime.

6. Users can drag ports from section 4 when they are under the ports tab to this section. This willbe the input port where traffic comes in.

7. Users can drag rules/filters from section 4 when they are under the filters tab to this section. Thisis the rule which will determine whether the type of traffic that is allowed to flow through to theoutput port or deny all traffic.

8. Users can drag ports and port groups from section 4 when they are under the ports or groupstab. This will be the output port(s).*

*If no port groups are created and user wishes to create a port group, users can drag ports on topof each other. A new window will pop up allowing the user to create a port group or virtual trunk forload balancing purposes.
