Chapter 9
Configuring Link Aggregation
For information on other configuration tasks for the EtherChannel, refer to the
Cisco IOS Configuration Fundamentals Configuration Guide.
Caution
The EtherChannel interface is the Layer 2/Layer 3 interface. Do not enable Layer 3 addresses on the
physical interfaces. Do not assign bridge groups on the physical interfaces because doing so creates
loops.
To assign Ethernet interfaces to the EtherChannel, perform the following procedure, beginning in global
configuration mode:
Command
Step 1
Router(config)# interface fastethernet
number
or
Router(config)# interface gigabitethernet
number
Step 2
Router(config-if)# channel-group
channel-number
Step 3
Router(config-if)# end
Step 4
Router# copy running-config startup-config

Purpose
Enters one of the interface configuration modes to
configure the Fast Ethernet or Gigabit Ethernet
interface that you want to assign to the
EtherChannel. You can assign any interface on the
system to the EtherChannel, but both interfaces
must be either FEC or GEC.
Assigns the Fast Ethernet or Gigabit Ethernet
interfaces to the EtherChannel. The channel
number must be the same channel number you
assigned to the EtherChannel interface.
Exits to privileged EXEC mode.
(Optional) Saves configuration changes to
NVRAM.
