Getting Started

Learn how to Matrix operates and how it is installed. Then learn how to configure its network settings and set the system time.



Operation of your Matrix is configured in an arrangement called a layout. The layout defines port connections, speeds, and the rules in use. You can also import and export layouts.


Ingress and Egress Ports

A network port is an ingress port that accepts network traffic. A tool port is an egress port that forwards network traffic to analysis tools. The connections must be made between (ingress) network ports and (egress) tool ports before rules can take effect.


Traffic Rules

Rules modify how and what packets are forwarded from network ports to tool ports. Rules contain filters and set options like trailers, load balancing, and packet deduplication, but rules only take effect when connected to ports.


Traffic Filters

Traffic filters function as a part of Viavi and ensure only specific traffic reaches your analysis tools.


User Accounts and User Groups

Mange your users, user groups, and authentication schemes either with the Matrix or a third-party service like Active Directory, LDAP, or others.



When traffic replication is used, a single data stream is copied and forwarded to multiple tool ports. Replication is necessary for providing identical traffic to different tools.


Aggregation and Speed Conversion

When link aggregation is used, traffic from multiple network ports is combined. The combined traffic can be forwarded to monitoring tools as a single stream of traffic. Speed conversion converts the speed and interface of a network link to something compatible with analysis tools.


Load Balancing

When load balancing is active, traffic becomes more evenly distributed to monitoring tools. This ensures the monitoring tools are not overwhelmed, and network visibility can be improved.


Packet Deduplication

Duplicate packets lower the statistical accuracy of analysis, increase network link saturation, and can interfere with tools. Packet deduplication removes duplicate packets and helps you avoid those situations.


Packet Trimming

Packet trimming limits the size of egress packets to no larger than a set value. Packets larger than the set value are reduced in size before being sent to analysis tools.



The latest firmware ensures maximum performance and stability of the Matrix, so you should always be on the latest version.



Your Matrix is pre-licensed. Relicensing the device requires that you request a new license from Viavi and then import a multi-line license string.



Logging captures events that occur in the application, hardware, and its ports. These events may range from informational to critical and can be used when troubleshooting.


Service and Repairs

Learn how to handle sensitive data before and after repairs or how to transfer your settings to another appliance.



Read answers to common questions or unique situations.
