What is the max ethernet frame size on a trunk link using ISL frame
encapsulation?

I was under the impression it was 1518, but i'm getting different feedback

thanks ppl

1518 bytes is the max. size of ethernet frames. When you use ISL, it
adds 30 bytes to that number (26 bytes header, 4 bytes tail to
encapsulate the frame).

So it's 1548 bytes (giant baby frame)
