Hardware-based Filtering allows the user to determine what type of traffic is copied from the network ports to the monitor ports based on Layer 2-7 criteria such as:
|
- MAC (source, destination)
- IP (source, destination, range)
- UDP/TCP/ICMP (port, range)
|
- VLAN, QoS, IP Service Type
- Even /Odd Ports for RTP/RTCP
- Custom offset / masking filter
|
|
The benefits of filtering include improved aggregation, reduced traffic load to each monitor interface, more efficient operation of each monitor tool (as it receives only relevant traffic / traffic of interest), and greater monitor tool ROI.
Since the filtering, at layer 2 up to 7, is performed in hardware, it is able to be performed at full line rate, on all streams, continuously.
Hardware-based Filtering is available on select models of traditional taps, and is available on all models of Distributed traffic Capture Systems™ (DTCS).
