I have conneccted a server with LACP on Nexus extender. I am starting different file copy from diffferent sources to this server, it does not load balance.
source addresse: 192.168.30.3 / 192.168.30.1
destination: 192.168.30.2
10 Po10(SU) Eth LACP Eth111/1/1(P) Eth111/1/2(P)
interface port-channel10
switchport
switchport access vlan 10
flowcontrol send on
interface Ethernet111/1/1
switchport
switchport access vlan 10
channel-group 10 mode active
no shutdown
interface Ethernet111/1/2
switchport
switchport access vlan 10
channel-group 10 mode active
no shutdown
This output says it is goinfg to different ports but NOT... 111/1/1 has no outgoing traffic..

Hello Muhammed,
load balancing should be based on EXOR of last significant bit of IP source address and last significant bit of IP destination address as in other Cisco platforms. (for a two links bundle)
You have tried file transfer starting from 192.168.130.1 and 192.168.130.3 both have less significant bit = 1, while the destination is always the same.
Try to start the File transfer using an even address so that less significant bit is 0 instead of 1, as for example using 192.168.130.250.
It should use the other member link as showed in the show command
Hope to help

sorry, i have typed it wrong..
i have tried this:
source addresse: 192.168.30.250 / 192.168.30.1
destination: 192.168.30.2
and
output shows different ports.. but not working.
