Fast EtherChannel Configuration Examples

Figure 10 shows four point-to-point Fast Ethernet interfaces that are aggregated into a single Fast EtherChannel interface.

Figure 10 Fast Ethernet Interfaces Aggregated into a Fast EtherChannel

	FE0/0	Fast EtherChannel 1
	FE0/1	(also called a port channel)
	FE1/0

The following is an example of how to create a Fast EtherChannel (port-channel interface) with four Fast Ethernet interfaces. In this example, ISL is enabled on the Fast EtherChannel and an IP address is assigned to the subinterface.

Router# configure terminal
Router(config)# interface port-channel	1
Router(config-if)# no shutdown
Router(config-if)# exit
Router(config)# interface port-channel	1.1
Router(config-if)# ip address 1.1.1.10	255.255.255.0
Router(config-if)#encapsulation isl 100
Router(config-if)# exit
Router(config)# interface fastethernet	0/0/0
Router(config-if)# no ip address
Router(config-if)# channel-group 1
Fast Ethernet 0/0 added as member-1 to	port-channel1.
Router(config-if)# exit
Router(config)# interface fastethernet	0/1/0
Router(config-if)# no ip address
Router(config-if)# channel-group 1
Fast Ethernet 0/1 added as member-2 to	port-channel1.
Router(config-if)# exit
Router(config)# interface fastethernet	1/0/0
Router(config-if)# no ip address
Router(config-if)# channel-group 1
Fast Ethernet 1/0 added as member-3 to	port-channel1.
Router(config-if)# exit
Router(config)# interface fastethernet	1/1/0
Router(config-if)# no ip address
Router(config-if)# channel-group 1
Fast Ethernet 1/1 added as member-4 to	port-channel1.
Router(config-if)# exit
Router(config)# exit
