Chapter 35      Configuring EtherChannels and Link-State Tracking
Configuring EtherChannels
single-MAC-address device, source-based forwarding on the switch EtherChannel ensures that the 
switch uses all available bandwidth to the router. The router is configured for destination-based 
forwarding because the large number of workstations ensures that the traffic is evenly distributed from 
the router EtherChannel.
Use the option that provides the greatest variety in your configuration. For example, if the traffic on a 
channel is only going to a single MAC address, using the destination-MAC address always chooses the 
same link in the channel. Using source addresses or IP addresses might result in better load balancing.
