You can use multiple taps/spans against one monitor.
Relevant to all versions.
Yes. A Network Monitor can monitor either:
In general, a Tap will present 2 ports of traffic, while a SPAN will present a single port of traffic.
There are 2 types of traffic load to be concerned with: unfiltered and filtered traffic (the traffic actually being monitored). The limits on NICS/Ports/Endace cards are as follows:
* An Endace installation can handle more than 700 Mbps of unfiltered traffic.
* A non-Endace installation can handle up to 80 Mpbs.
* In each case, this amount of traffic is the total traffic presented to all monitored ports.
* In either case, the filtered traffic should be less than 20 Mbps of traffic (2 x 3 Ghz system) to 40 Mbps (4 x 3Ghz system)
These limits were determined by running tests with a lot of traffic (unfiltered) and a small amount of filtered traffic and validating accuracy on the filtered traffic.
