1)  Be mindful of the number of component-links you can put into a
single LAG.  This varies by platform.  In general, for higher-end
routers/switches the minimum number of component-links in a single
LAG is 16.

Some older equipment will unequally prefer certain links over others, depending on the number of members in the LAG. I.e. a 2-member LAG might load balance equally under ideal conditions, but a 3-member LAG might naturally load balance 2:2:1. This is particularly a problem if you have, say an 8-member LAG and you lose a single member, which could drop your overall throughput to the total of 4 members.
