Advanced Network Packet Broker

The EX484-3 series Network Packet Broker is a cost-effective solution for high port density 10/40G networks and offers expanded features over the previous Packetmasters such as packet slicing and user-defined filters.

The EX484-3 features 48 x 1 or 10G SFP+ and 6 x 40G QSFP interfaces offering exceptional port density and features in a device that is sure to maximize your ROI. The 6 x 40G QSFP ports also support breakout cables to individual 4 x 1/10G connections bringing the 1/10G link capacity up to a possible 72 x 1/10G interfaces.

The EX484-3 is ideal in environments where tools need access to 1G, 10G, or even 40G links. Multiple 40G ports also offer the possibility to create a high-bandwidth backbone between Packet Brokers or backhaul to and from remote sites. The high port density, session-aware load balancing, and tens of thousands of filtering rules at the user’s disposal combine to make the EX484-3 a device that can support large amounts of monitoring and security appliances or grow with an organization as they transition into 40G infrastructure.

Main Features of EX484-3

  • Filters and load-balances traffic from a 10 Gbps or 40 Gbps link to multiple 1 Gbps monitoring tools
  • Aggregates multiple 1 Gbps links to 10 or 40 Gbps monitoring tools
  • 48 x 1/10 Gbps (SFP/SFP+) and 6 x 40 Gbps (QSFP)
  • Supports traffic modifications up to layer 4 as well as changing, removing and adding VLAN, MPLS, VXLAN,
    NVGRE, GRE, GENEVE tags/ tunnels
  • IPv6 support
  • No additional port licensing fees or software feature licensing. All features and applications included in the unit price.
  • 2-year warranty period

Functions & Benefits of EX484-3

  • Finite Rule Life: Rules can be set with a timeout period where the rule will be removed automatically after a set period of time or a set period without traffic activity. Rules can be dynamically created via the REST API.
  • Generate sFLOWS CDRs: The EX484-3 is able to generate standard-conform sFlow information of the incoming
  • Easy to configure: Via Web GUI (HTTPS supported)
  • GRE / VXLAN Tunnel support: The Packetmaster EX484-3, like all Packetmaster Series NPBs, can function as a GRE / VXLAN tunnel endpoint.
  • Load balancing: L2 / L3 / L4 hash-based, session aware load balancing, up to 15 load balancing groups
  • Cubro Vitrum Management Suite: EX484-3 is fully compatible with Cubro Vitrum, a centralized management platform for all Cubro network visibility solutions.

Extended Functions

The management host controller of every Packetmaster EX unit runs a minimal Debian Linux OS as the operating system. This Linux OS natively supports core Unix shell commands and utilites, shell scripting, Python 2.7, and the VI text editor.

This allows the user to create and run custom scripts and command sets to extend the functionality of the Packetmaster EX for their environment. Cubro can also create custom application for the customers specific needs as well.


  • A Perl script collects counters and writes these counters in an external SQL Database for later analysis.
  • A Python script reads files from a server and creates filters based on this data.
  • A Python script dynamically changes filters based on link load data collected from another Packetmaster.
  • A shell script pings different devices and changes filter rules based on ping response.

Traffic aggregation from many input ports to one or many output ports. This also works with different link speeds of up to 40 Gbps.

4500 flow rules (filters) can be set in the unit. The fields marked with a red dot can be used as a match for a packet, stand-alone, combined or with wild cards. For IP Src and IP Dst supernets are supported.

Available actions after a positive match include:

  • Output: Forward the traffic to one or more ports (even the input port)
  • Drop: Drop (discard) the traffic
  • Modify: Modify header information such as VLAN tag, MPLS label, source MAC, destination MAC, source IP, destination IP, source Port, and destination Port.
  • Add VLAN tag: The Packetmaster EX units can add or append VLAN tags to the filtered traffic to separate or identify it after aggregation/output. (Up to six VLAN tags are possible).
  • Strip VLAN: Remove VLAN tag(s) (Q in Q support).
  • Add MPLS: Add an MPLS Tag to a matched packet
  • Strip MPLS: Remove an MPLS Tag from a matched packet
  • Rule Priority/Rule Stacking: The ability to prioritize filtering rules allows for very complex filtering possibilities.
