Link aggregation group cable length

[Mark R]

Do the cables in a LAG have to be the same length? (Just for interest really, not for a project).

E.g. if I have 2 10G ports and aggregate them under 802.3ad, each running LR, what would happen if 1 of the links had a length of 3 miles, and the other link 5 miles (let's say that it was taking a redundant route)?

Would it work? Would the latency discrepancy be an issue?

1ms of latency is over 100miles of fiber. So in the scope you used, no there would be no issue.

.82ms per 100miles of fiber is the typical rough estimate.
