Brocade Switch: Adding Sflow To A LAG On An ICX Switch

I like the capabilities of sflow.  I needed to add sflow to a LACP LAG that was set up.  You have to name the primary port.  Here is my LAG config before adding sflow:
lag "LAG_1" dynamic id 1
 ports ethernet 1/1/8 to 1/1/12
 primary-port 1/1/8
 deploy

Here is the config to add sflow:
SSH@Core(config-if-e1000-1/1/8)#lag "LAG_1" dynamic id 1
SSH@Core(config-lag-LAG_1)#sflow forward eth 1/1/8
SSH@Core(config-lag-LAG_1)#

Here is the config after I added sflow:
lag "LAG_1" dynamic id 1
 ports ethernet 1/1/8 to 1/1/12
 primary-port 1/1/8
 deploy
 sflow forwarding ethernet 1/1/8
 port-name ***_5G_To_Server_Room_*** ethernet 1/1/8
 sflow forwarding ethernet 1/1/9
 sflow forwarding ethernet 1/1/10
 sflow forwarding ethernet 1/1/11
 sflow forwarding ethernet 1/1/12
