Chapter 37 Configuring EtherChannels and Link-State Tracking
Configuring EtherChannels
Beginning in privileged EXEC mode, follow these steps to create a port-channel interface for a Layer 3
EtherChannel. This procedure is required.
To remove the port-channel, use the
no interface port-channel
port-channel-number
global
configuration command.
This example shows how to create the logical port channel 5 and assign 172.10.20.10 as its IP address:
Switch#
configure terminal
Switch(config)#
interface port-channel 5
Switch(config-if)#
no switchport
Switch(config-if)#
ip address 172.10.20.10 255.255.255.0
Switch(config-if)#
end
Configuring the Physical Interfaces
Beginning in privileged EXEC mode, follow these steps to assign an Ethernet port to a Layer 3
EtherChannel. This procedure is required.
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
interface port-channel
port-channel-number
Specify the port-channel logical interface, and enter interface
configuration mode.
For
port-channel-number
, the
range is 1 to 64.
Step 3
no switchport
Put the interface into Layer 3 mode.
Step 4
ip address
ip-address mask
Assign an IP address and subnet mask to the EtherChannel.
Step 5
end
Return to privileged EXEC mode.
Step 6
show etherchannel
channel-group-number
detail
Verify your entries.
Step 7
copy running-config startup-config
(Optional) Save your entries in the configuration file.
Step 8
Assign an Ethernet port to the Layer 3 EtherChannel. For
more information, see the
Interfaces” section on page 37-15
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
interface
interface-id
Specify a physical port, and enter interface configuration mode.
Valid interfaces include physical ports.
For a PAgP EtherChannel, you can configure up to eight ports of
the same type and speed for the same group.
For a LACP EtherChannel, you can configure up to 16 Ethernet
ports of the same type. Up to eight ports can be active, and up to
eight ports can be in standby mode.
Step 3
no ip address
Ensure that there is no IP address assigned to the physical port.
Step 4
no switchport
Put the port into Layer 3 mode.
