XS748T - LAG question
I have 2 Link Aggregations set on my switch. One is 2 10Gpbs ports and another is 4. The first connects to a Freenas box and the second to a Linux box. Both boxes have a LAG set up of 2 or 4 ports...
“This is equivalent to having one interface with 3 GBPS speed.”
The above statement is false. Setting up a LAG may increase the bandwidth of a link, but ‘bandwidth’ is not the same as ‘speed’. And, it just may to some degree. It all depends on the load balancing algorithm being employed and the usage of the environment.
Often, only the load balancing algorithm based on the source and destination MAC addresses is employed when selecting the network interface for a transmission. If those addresses do not change, one and the same interface is always used. That’s what happens when you run just a single iperf session. If you set up two parallel iperf sessions using two different PCs communicating with the same server, each session most likely will run at the speed close to 10 Gb/s. Without a LAG, each session would run with the speed close to 500 Mb/s.
