EtherChannel Configuration Example
For information on other configuration tasks for the EtherChannel, ref er to the
Cisco IOS Configuration Fundamentals Configuration Guide.
To assign Ethernet interfaces to the EtherChannel, perform the following procedure, beginning i n global
configuration mode:
EtherChannel Configuration Example
Figure 10-1 shows an example of EtherChannel. The associat ed commands are provided in
Example 10-1 (Switch A) and Example 10-2 (Switch B).

Command Purpose
Step 1 Router(config)# interface fastethernet
number
or
Router(config)# interface gigabitethernet
number
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 Ethernet
interface on the system to the EtherChannel, but
both interfaces must be either FEC or GEC.
Step 2 Router(config-if)# channel-group
channel-number
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.
Step 3 Router(config-if)# end Exits to privileged EXEC mode.
Step 4 Router# copy running-config startup-config (Optional) Saves configuration changes to
NVRAM.
