Visibility into network traffic has traditionally been important for network operations, compliance, and security. Traditionally, network traffic monitoring has been performed using test access points (TAPs) and Cisco® Switched Port Analyzer (SPAN) along with a purpose-built matrix switch to replicate and forward the traffic to different monitoring tools. This approach has become more challenging as network and application traffic volume has increased and as traffic has shifted to an east-west pattern. This shift in traffic pattern requires customers to move their monitoring domains from the aggregation layer to the access layer or the top of the rack for better visibility.
Cisco Nexus® Data Broker offers a cost-effective alternative to traditional TAP and SPAN aggregation solutions for network traffic monitoring. This simple and scalable solution offers several flexible implementation options that can appeal to a wide variety of customers.
