Step 6

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

Current configuration:
!

no switchport
no ip directed-broadcast
channel-group 1 mode desirable
end
Switch# show interfaces fastethernet 5/4 etherchannel

Chapter 24 Configuring EtherChannel and Link State Tracking
Purpose
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.

C - Device is in Consistent state.
P - Device learns on physical port.
