Configuring EtherChannel
To configure Layer 2 Ethernet interfaces as Layer 2 EtherChannels, perform this task for each interface:
Command
Step 1
Switch(config)# interface {fastethernet | gigabitethernet
| tengigabitethernet} slot / port
Step 2
Switch(config-if)# channel-group port_channel_number mode
{active | on | auto | passive | desirable}
Step 3
Switch(config-if)# end
Step 4
Switch# show running-config interface {fastethernet |
gigabitethernet} slot / port
Switch# show interface {fastethernet | gigabitethernet |
tengigabitethernet} slot / port etherchannel
This example shows how to configure Fast Ethernet interfaces 5/6 and 5/7 into port-channel 2 with PAgP
mode desirable:
Switch# configure terminal
Switch(config)# interface range fastethernet 5/6 - 7 (Note: Space is mandatory.)
Switch(config-if-range)# channel-group 2 mode desirable
Switch(config-if-range)# end
Note See the
keyword.
This example shows how to verify the configuration of port-channel interface 2:
Switch# show running-config interface port-channel 2
Building configuration...
Current configuration:
!
interface Port-channel2
switchport access vlan 10
switchport mode access
end
Switch#
The following two examples show how to verify the configuration of Fast Ethernet interface 5/6:
Switch# show running-config interface fastethernet 5/6
Building configuration...
Current configuration:
!
interface FastEthernet5/6
switchport access vlan 10
switchport mode access
channel-group 2 mode desirable
end

Purpose
Selects a physical interface to configure.
Configures the interface in a port-channel and
specify the PAgP or LACP mode.
If you use PAgP, select the keywords active
and desirable.
If you use LACP, select the keywords active
and passive.
Exits configuration mode.
Verifies the configuration.
