I'm concerned that I'm misunderstanding how aggregators work in the scenario below:
I have a project where I need 40 Gbps links between switches. My plan was to have my three switches use all four of the 10Gb uplink ports to a fourth "aggregator switch" so that I'd have the necessary bandwidth for a total of 12 10Gb links to the aggregator.
Does link aggregation truly work as if you have an aggregated link? Is this how I want to achieve the 40Gb uplink between switches?
According to IEEE 802.1ad specification, it strikes me as being more about failsafe/failover than about using multiple links to achieve a larger pipe.
If this is not the correct approach can someone suggest a better and more common approach?
