EtherChannel has been a part of the Cisco IOS for many years, so you should find that all your switches support it with proper configuration. Do not be afraid to enable it on a pair of ports and try it. When setting up an EtherChannel connection, remember the following points; they can help you avoid problems during the configuration process:. You can configure up to eight ports, and all of these ports should be the same type Fast Ethernet, Gigabit Ethernet. Ensure that all ports are enabled and that none have been configured using the shutdown command. Switchport settings from the first port in EtherChannel are copied to all other ports in the EtherChannel when the ports are added to the channel group.

EtherChannel allows multiple physical Fast Ethernet or Gigabit Ethernet links to be combined into one logical channel. When adding a VLAN, be sure to do it only for the port channel.

Cisco Switch EtherChannel Configuration – LACP – PAgP
Assume we have a Data Room switch providing access to servers. This switch is connected to a Distribution switch which aggregates traffic from several user access switches. If we connect the two switches together with a single 1Gbps interface, then it could potentially be a bottleneck to traffic from users to servers especially for high-volume applications. With Etherchannel, we can bundle together up to 8 interfaces to form a single logical link Port-Channel and traffic is load-balanced between all interfaces.
