Lösungen - Two 10G Link Aggregators in One

The 10G/1G Link Aggregator (LA-1400) collects traffic together from as many as ten network links and sends it all to four monitoring tools. But even if you have ten links to monitor, sometimes you don't want to aggregate all of them at once. For example:

• If the aggregated traffic exeeds your monitoring tool's capacity
• If you want to keep certain traffic separate, for example, outgoing and incoming traffic
• If you want to take advantage of two NICs on your monitoring tool

If you want to aggregate two separate traffic groups, then the new 10G/1G Dual Link Aggregator (LA-1450) is what you need. Like the LA-1400, the LA-1450 has 14 SFP+ ports in a 1U chassis.

However, the LA-1450 ports are partitioned into two separate link aggregators. Each one aggregates traffic from five network links and sends it to two monitor ports.


In this architecture, the fiber tap devices tap the transmit and receive data of the four network links. The transmit and receive data are physically separated and connected to the 10G/1G Dual Link Aggregator in the assigned ports. The transmit data connects to network ports 1, 2, 3, and 4, and the receive data connects to network ports 6, 7, 8, and 9. Network ports 5 and 10 are spare in this application.
The data from network ports 1 through 5 (all of the transmit data) is aggregated and sent to monitor ports 1 and 2, while the data from ports 6 through 10 (all of the receive data) is aggregated separately and sent to monitor ports 3 and 4. If the network links are 1 Gigabit speed, the maximum possible traffic through any monitor port to the transaction latency measurement tool is 4 Gigabits.
