FULL NETWORK VISIBILITY WITH EXPANDED MONITORING SOLUTIONS Expand an existing SPAN (Port Mirror) or Tap port monitoring capability with the USR® 10/100/1000 Variable 4 Port Aggregator and Regenerator. Dual purpose hardware provides the option to share identical copies of data made by Tap or SPAN ports to multiple tools for security, storage or recording purposes - or combine Tap and SPAN port data into one combined stream for complete visibility into network traffic. The 3:1 mode faultlessly combines and processes up to three streams of data into a single data stream allowing a single monitoring tool access to a larger portion of the network. The 1:3 mode replicates up to 3 copies of data, and when used with an Aggregation Tap like the USR4503 can increase visibility to four monitor ports, sending identical copies to separate network tools (analyzer, IDS, probe) for simultaneous monitoring and analyzing. Eliminate SPAN port contention, oversubscription, and configuration errors with this easy to install and port saving device. Ideal for security applications or anywhere you need dedicated access to your network links for advanced or consolidated monitoring.
