Chapter 24 Configuring EtherChannel and Link State Tracking
Configuring EtherChannel
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
Note See the “Configuring a Range of Interfaces” section on page 7-4 for information about the range
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
Port state = EC-Enbld Up In-Bndl Usr-Config
Channel group = 1 Mode = Desirable Gcchange = 0
Port-channel = Po1 GC = 0x00010001 Pseudo-port-channel = Po1
Port indx = 0 Load = 0x55
Flags: S - Device is sending Slow hello. C - Device is in Consistent state.
A - Device is in Auto mode. P - Device learns on physical port.
Step 3
Switch(config-if)# no ip address
Ensures that no IP address is assigned to the physical
interface.
Step 4
Switch(config-if)# channel-group port_channel_number
mode {active | on | auto | passive | desirable}
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.
Step 5
Switch(config-if)# end
Exits configuration mode.
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
Verifies the configuration.
