7.2.4.1.5.2 Example Filtered VERSAstream
The Aggregation Configuration tab modifies the routes used by the Filtered
VERSAstream™ and Network input port can be routed to multiple Monitor Ports if
desired. Additionally, traffic from multiple Network input ports can be routed to
a single Monitor Port if desired. The
Readback button shows the current
Aggregation Configuration. After making changes, click the Apply button for the
changes to take affect.
Non-Aggregation Example:
Reduce the chance of oversubscribing
the throughput capacity of a
monitoring tool. 100BaseT and
1000BaseT monitoring tools are rarely
capable of accepting sustained input
at full line rate. Sending the separate
data streams from multiple SPAN ports
or aggregation taps, to different
Filtered product Monitor ports and
thereby to different NIC's on a
multiple port monitoring tool is a useful strategy for overcoming the inherent
shortcomings of monitoring tool throughput.
Direct the copies of Inbound and Outbound network traffic coming from non-
aggregating taps or SPAN ports (assuming one has different SPAN ports - one
set up to forward Inbound traffic on certain network switch ports and the other
forwarding copies of Outbound traffic) to different NIC's on a monitoring tool
that does analysis of Conversation Flows. Tools of this type require the Inbound
and Outbound traffic copies to be received on separate NIC's.
The flow of network traffic in the diagram
above, can be replicated by the
Aggregation Configuration shown below.
Data received on Network Port 1 is sent
to Monitor Port 5. Data received on
Network Port 2 is sent to Monitor Port 6.
Monitoring devices connected to Monitor
Ports 5 and 6 receive different data
streams.
