I think I configured LAG correctly on my Dell powerconnect 5448 after going over the manual carefully with 6 ports to another Dell 5448. But the LEDs on the LAG ports blinks separately. I remember that the LEDs blink together if the ports are in LAG configuration. How do I verify the LAG is configured and working properly?
Also, if 6 ports are in LAG, when frame is sent, does LAG do load balancing or bundling the bandwidth so that frame is divided and is sent in multiple paths(I don't know how it can do, but...). If it's load balancing, what's the difference between just hooking up 6 ports between the two switches without LAG? switch finds any empty path to send to next switch, doesn't it?
