I was working to establish LAG between two EX4200s. I configured the link speed as 100m on the ae0 & the two participating physical interfaces. Then, I connected two laptops on both switches to check transfer speed via Etherchannel; I got 100 mbps at max. Though, the below output of ae0 interface shows link speed of 200 mbps. Can somebody explain the situation ..... like why I'm not getting double speed?
Laptops are connected over 1G with both switches.
