Example 17-12
Layer 3 EtherChannel Configuration on Switch SW1
interface GigabitEthernet1/0/13
no switchport
no ip address
channel-group 12 mode on
!
interface GigabitEthernet1/0/14
no switchport
no ip address
channel-group 12 mode on
!
interface Port-channel12
no switchport
ip address 10.1.12.1 255.255.255.0
Of particular importance, note that although the physical interfaces and PortChannel interface 
are all routed ports, the IP address should be placed on the PortChannel interface only. In fact, 
when the 
no switchport
command is configured on an interface, IOS adds the 
no ip address
command to the interface. Then configure the IP address on the PortChannel interface only.
Once configured, the PortChannel interface appears in several commands, as shown in 
Example 17-13. The commands that list IP addresses and routes refer to the PortChannel 
interface. Also, note that the 
show interfaces status
command lists the fact that the physical 
ports and the port-channel 12 interface are all routed ports.
