3:1 SPAN/TAP Port Traffic Aggregation or 1:3 SPAN/TAP Port Traffic Duplication

• Provides aggregation or regeneration options
• Combine up to 3 TAP or SPAN/mirror port network links into one stream
• Share up to 3 identical copies of data from a TAP or SPAN/Mirror port to multiple tools
• Separation of Duty – use switch for switching traffic, a TAP for initial aggregation and the USR4504 for multiple monitoring applications
• Decrease reliance on switch resources for increased network management visibility

Product Description

The USR4504 10/100/1000 Variable 4 Port Aggregator and Regenerator expands existing SPAN (Port Mirror) or TAP (Test Access Point) port monitoring capability. 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 the USR4504. Ideal for security applications or anywhere you need dedicated access to your network links for advanced or consolidated monitoring.

USR4504 Features


    View entire full duplex conversations using single interface monitoring tools
    Improve visibility into the network – including VLAN tags
    Decrease reliance on switch resources for network management visibility
    Eliminate SPAN port contention, oversubscription, and configuration errors
    Easily share monitor ports for improved monitoring without maintenance windows
    Ideal for Intrusion Detection System (IDS) applications


    Duplicate traffic from a single TAP or SPAN port to up to 3 monitoring tools
    Access to the same links for system redundancy, testing and advanced monitoring applications
    Expand access to data across company assets and provide a wider variety of data to each department
    Improve overall switch performance by removing port mirror degradation while freeing valuable ports


    Combine multiple network links or channels from TAP, SPAN, or mirror ports into one stream
    Monitor network traffic from up to three different sources through a single-interface monitoring tool
    Visibility into complete network conversations, including full-duplex conversations
    Provide security or analysis to a larger part of the network by allowing single port device access to traffic from multiple points in the network


    No MAC or IP settings on the traffic ports makes the device invisible to the network
    Unidirectional passive traffic makes it impossible to access or infiltrate connected monitoring and analysis tools
    Redundant power supply option ensures seamless monitoring even if the main power source is unavailable*
