z/VM Virtual Networking Link Aggregation - Cisco 6509 with LACP

The following commands will configure the 6509 to run an etherchannel with two physical ports that are setup to run LACP mode. This would be used to configure for connection to a VSWITCH port group with 2 OSA port connections when the VSWITCH port group is configured with LACP Active.

To configure more ports, just increase the interface range in the second command (you can also configured a single interface with the command "interface gigabitEthernet 2/23"). Note also that if you need to configure two non-consecutive interfaces, you will need to do them both separately. For instance in the command sequences show below you would have to configure commands 2-5 below twice, once for, say, "interface gigabitEthernet 2/20" and once for "interface gigabitEthernet 2/23".

vm6509#configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.
 
vm6509(config)#interface range gigabitEthernet 2/23 -24

vm6509(config-if-range)#channel-protocol lacp
 
vm6509(config-if-range)#channel-group 10 mode active
