This example shows how to configure EtherChannel to use source and destination IP addresses:
Router# configure terminal
Router(config)# port-channel load-balance src-dst-ip
Router(config)# end
Router(config)#
This example shows how to verify the configuration:
Router# show etherchannel load-balance
Source XOR Destination IP address

Configuring the EtherChannel Min-Links Feature

The EtherChannel Min-Links feature is supported on
configure the minimum number of member ports that must be in the link-up state and bundled in the
EtherChannel for the port channel interface to transition to the link-up state. You can use the
EtherChannel Min-Links feature to prevent low-bandwidth LACP EtherChannels from becoming active.
This feature also causes LACP EtherChannels to become inactive if they have too few active member
ports to supply your required minimum bandwidth.
To configure the EtherChannel Min-Links feature, perform this task:
Command
Step 1
Router(config)# interface port-channel number
Step 2
Router(config-if)# port-channel min-links number
Router(config-if)# no port-channel min-links
Step 3
Router(config-if)# end
Step 4
Router# show running-config interface type
slot/port
Router# show interfaces type
etherchannel
Note Although the EtherChannel Min-Links feature works correctly when configured only on one end of an
EtherChannel, for best results, configure the same number of minimum links on both ends of the
EtherChannel.
