Hi CSC,
I have configured a etherchannel and lacp and looks fine
Port-channel1 is up, line protocol is up (connected)
Hardware is EtherChannel, address is 1833.9def.3601 (bia 1833.9def.3601)
Description: INSIDE-MASTER
MTU 1500 bytes, BW 8000000 Kbit, DLY 10 usec,
reliability 255/255, txload 33/255, rxload 28/255
Members in this channel: Gi1/0/1 Gi1/0/2 Gi2/0/1 Gi2/0/2 Gi3/0/1 Gi3/0/2 Gi4/0/1 Gi4/0/2
but there is an issue at the load-balancing, interface Gi1/0/2 is prefered over the other interfaces, load-balancing method is src-mac address
GigabitEthernet1/0/1 reliability 255/255, txload 10/255, rxload 31/255
GigabitEthernet1/0/2 reliability 255/255, txload 233/255, rxload 30/255
GigabitEthernet2/0/1 reliability 255/255, txload 1/255, rxload 32/255
GigabitEthernet2/0/2 reliability 255/255, txload 11/255, rxload 30/255
GigabitEthernet3/0/1 reliability 255/255, txload 1/255, rxload 28/255
GigabitEthernet3/0/2 reliability 255/255, txload 1/255, rxload 31/255
GigabitEthernet4/0/1 reliability 255/255, txload 11/255, rxload 30/255
GigabitEthernet4/0/2 reliability 255/255, txload 1/255, rxload 33/255
there are 5 mac address at the end do of the portchannel as a sorce mac address, but after xor'ing them i found (sort of) that 2 of the macaddress should be taking the GigabitEthernet4/0/1 path.
I been thinking about some troubleshooting scenarios:
1. shutdown GigabitEthernet1/0/2
2. shu / no shu po1
3. reboot switch
Please let me know your experience and recomendations, I appreciate your help
Best Regards,
Eleazar

Does the traffic on the channel go primarily to the same MAC? If so try switching up the load balance to dest-mac, src-dest-mac, dest ip, src-i
It really depends on the traffic patterns

Thanks for the help.
Change the load-balancing method is one good option but Possibly the only options that can choose rigth now are
>1. shutdown GigabitEthernet1/0/2
>2. shu / no shu po1
>3. reboot switch
If there is recomendations or comments about doing this at portchannel, I appreciate your help
thanks for your help

I'm not sure the restriction your are running into but:
Conf t
Port-channel load-balance {src-mac | dst-mac | src-dst-mac | src-ip | dst-ip | src-dst-ip | src-port | dst-port | src-dst-port}
