Understanding Port-Channel Interfaces
When you create an EtherChannel for Layer 2 interfaces, a logical interface is dynamically created. You
then manually assign an interface to the EtherChannel by using the channel-group interface
configuration command as shown in Figure 10-2.
Each EtherChannel has a logical port-channel interface numbered from 1 to 6.
