Etherchannel Load-Balancing issue

Etherchannel Load-Balancing issue

Etherchannel Load-Balancing issue

Hi tek-tip forum,

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 regarding 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.

at this time i'm not allowed to change the load-balancing method (which right now is src-mac)

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 about the troubleshutting scenarios described above, I appreciate your help

Best Regards,
