Good morning guys,
A very quick question. If I have an LCAP etherchannel consisting of 2 physical 1Gb/s interfaces. Does the channel get aggregated to 2Gb/s throughput?
My understanding was that whilst theoretical throughput would be 2Gb/s, actual throughput would not achieve higher than 1Gb/s? Is this correct or is 2Gb/s achievable?
Regards.

Hi,
for the same "flow" which defined by port-channel load balance algorithm you will have maximum of 1 GB. Etherchannel cant provide load sharing (sharing traffic of the same flow between different physical interfaces). But in general you may have 2GB traffic in total as a result of different flow traffic.

Thank you.
So from device A to device B, you would have a maximum of 1Gb/s over the channel. However, device C and device D may have a separate flow running concurrently at 1Gb/s which would bring the channel utilisation up to 2Gb/s.

True, but if port-channel defines different physical links based on hashing algorithms. :)
