Hi,
I have configured the trunk interface and LACP on CMTS. The both interfaces are up, but I notice that bandwidth is not balanced.
On gige 0 port is whole download traffic, on gige 1 is just upload traffic.
On gige 0 is approx 800 Mibt/s and I don't know why is not balanced between both of them.
Does anybody have some experiences?
Thans in advance, 0603
interface trunk 1
gige 0 mode active
gige 1 mode active

interface gige 0

interface gige 1

Try to add lacp port-priority to interface gige0 and gige1:
interface gige 0
lacp port-priority 10
interface gige 1
lacp port-priority 10
and in global config mode:
lacp system priority 60000

Thanks for quick reply. I tried as you suggest and a lot of other combinations with "priority" but don't notice any change.
On gige 0 is still the whole downstream, on gige 1 a half of upstream traffic but no dowstream.

Hi,
for the Downstream (CMTS receiving data) you'll need also a proper LACP configuration on the opposite site of the CMTS NSI interface.
You told that the upstream traffic is now distributed over both interfaces (half per gige interface). So the CMTS is doing its work.
For the Downstream the Router or Switch in front of the CMTS has to do LACP work too.
Thanks Wittmann. You have right.
Because the upload is distributed 50% 50% per interface. Only the download trafic is just on one of both interfaces.
So, you have right...I must check the LACP config on uplink device of the CMTS..in my case the Nokia router.
I will post the solution.
Thanks one more time for pinpoint me to the solution :)
