You cannot add the following types of ports into an aggregation group: mirroring
port, port with static MAC address configured, port with static ARP configured, port
with 802.1x enabled.
z
When an aggregation group contains only one port, you cannot remove the port
unless you remove the whole aggregation group.

If you add more than four ports to an aggregation group, load sharing is
implemented on the four ports with smaller port numbers, and the rest ports serve
as link backups.

GigabitEthernet1/0/3, so that incoming/outgoing load can be shared among the
member ports.
