Configuring EtherChannel
Command
Step 1
Switch(config)# interface {fastethernet |
gigabitethernet | tengigabitethernet} slot/port
Step 2
Switch(config-if)# no switchport
Step 3
Switch(config-if)# no ip address
Step 4
Switch(config-if)# channel-group port_channel_number
mode {active | on | auto | passive | desirable}
Step 5
Switch(config-if)# end
Step 6
Switch# show running-config interface port-channel
port_channel_number
Switch# show running-config interface {fastethernet
| gigabitethernet | tengigabitethernet} slot/port
Switch# show interfaces {fastethernet |
gigabitethernet | tengigabitethernet} slot/port
etherchannel
Switch# show etherchannel 1 port-channel
This example shows how to configure Fast Ethernet interfaces 5/4 and 5/5 into port channel 1 with PAgP
mode desirable:
Switch# configure terminal
Switch(config)# interface range fastethernet 5/4 - 5 (Note: Space is mandatory.)
Switch(config-if)# no switchport
Switch(config-if)# no ip address
Switch(config-if)# channel-group 1 mode desirable
Switch(config-if)# end
See the
Note
keyword.
The following two examples show how to verify the configuration of Fast Ethernet interface 5/4:
Switch# show running-config interface fastethernet 5/4
Building configuration...
Current configuration:
!
interface FastEthernet5/4
no ip address
no switchport
no ip directed-broadcast
channel-group 1 mode desirable
end
Switch# show interfaces fastethernet 5/4 etherchannel

Purpose
Selects a physical interface to configure.
Makes this a Layer 3 routed port.
Ensures that no IP address is assigned to the physical
interface.
Configures the interface in a port channel and
specifies the PAgP or LACP mode.
If you use PAgP, enter the keywords auto or
desirable.
If you use LACP, enter the keywords active or
passive.
Exits configuration mode.
Verifies the configuration.
