Testing with Network Analyzers
Most network analyzers can perform many of the following functions:
Filter traffic that meets certain criteria so that, for example, all traffic to and from a particular device
•
can be captured.
Time-stamp captured data.
•
Present protocol layers in an easily readable form.
•
Generate frames and transmit them onto the network.
•
Incorporate an "expert" system in which the analyzer uses a set of rules, combined with information
•
about the network configuration and operation, to diagnose and solve, or offer potential solutions
to, network problems.
