Cristina,
When you have more than one port connect to another switch, spanning tree
will disable all but one of the port. If that port (live) connection is
cut, spanning tree will enable one of the other port to transfer data. This
process waste ports that's disable. When you use Fast EtherChannel, the
switch will use all the ports to move data. Better use of ports. When you
set up the EtherChannel, the switch will decide that these MAC address will
use this port and these MAC address will use that port (I don't know the
math for this). If one of the port goes down, it will automatically use the
other port(s) to forward the data. This is the same as using two routers to
load balance and backup.

Subject: FastEtherChannel!
All,
Fast Ether Channel is a trunking technology based on grouping together up to
4 full duplex 802.3 Fast Ethernets to provide fault-tolerant high-speed
links between switches, routers, and servers...My questions to you are:
How does it work? Which channel out of the four(2) channels is the default
one? Does it look at the MAC address in order to foward packets!!!!!!
Thank you all.
Cristina
