It binds two or more interfaces togetgher and sends/receives packets round-robin (well on Sun
there are different polices that gorven this behavior, round-rboin is just but one) between the
two. It provides instant failover as well as bandwidth consolidation. I have sun systems that have
4-gb bandwidth accross a single 'interface' using 4 copper gigabit cards.

The downfall is that your switch also has to support port aggregation. (any decent enterprise
quality switch surely will)

It offers a very clean and robust solution for protecting against NIC failure and also provides
added performance.

Hope this helps...
