Network Taps, in addition to being available for copper or fiber media, can be purchased in a fixed configuration, typically called “duplex Taps” – or as “Aggregation Taps.” The latter category offers options for how the data copies are distributed among the monitor ports. This article will clarify the differences between the two Tap types, as well as exploring the rationale for different Tap configurations, and examples of their applications.
In my previous articles we reviewed the overall topic of management interfaces to Taps and NPBs and took a deeper dive into Fault Management. In this chapter we will focus on the areas of configuration and provisioning management topics. Subsequent chapters will cover other management topics including software management, accounting, performance monitoring, security and remote access.
Security scanning of critical devices should be standard practice on networks, but what about other devices such as TAPs, Network Packet Brokers (NPB) and Bypass switches?
This article is the second in a multi-part series on the management of Taps and Network Packet Brokers. This chapter focuses on Fault Management including Detection, Correlation/Aggregation, Diagnosis/Isolation, Restoration, and Resolution.
