Hi
I have 2 1Gb ethernet ports in LACP/802.3ad to an Ubuntu server. The Ubuntu server has LACP/802.3ad configured and is able to transmit outbound at ~1.8Gb/s successfully, but, after trying many options, it can only receive at 1Gb/s.
After reading through many posts on this forum, I can tell that my server is only receiving data on one of the interfaces (whichever one the 7750 sets as primary).
Does anyone know how you change the hashing mechanism so that the SR will send on both interfaces?
Thanks
LACP load balancing
Re: LACP load balancing
It depends the nature of your traffic but if you haven't enabled it, you might like to try
configure system l4-load-balancing
Take a look at the section "LAG and ECMP Hashing" in the SR OS Interface Configuration Guide for how the hashing works for various types of traffic and the various options available.

Re: LACP load balancing
Hello guys,
I have different problem. when I use LAG with configuration like this
The lag utilization is unbalanced, when the one port is high until 100%, and other port still ~0.00%. I use ostinato to generate traffic and then I inject the traffic using access port (SAP) from VPLS.
I using command lsr-load-balancing lbl-ip but it's not effect with lag.
When I Use command, l4-load-balancing, it's also can't give effect to lag
Any advice from this event, Hope you can help me guys.
Thanks

Re: LACP load balancing
Hi!
Few questions:
On the drawing I see ports 4/2/11 and 4/2/12, but your LAG is 4/2/11 and 4/2/13. Where is typo?
How many IP flows do you send?
I also see that you send traffic in one direction. Better to send a small stream with reverted mac addresses to be sure that you traffic is treated as unicast, otherwise it will be broadcasted via multipoint queue.

Re: LACP load balancing
Hi jeniver,
the port from pict is typo. I'm sorry.
Additional information. I stream 2 IP flow. this the update from my activity. Each stream I using 1000 pps. Each stream I using pair of MAC, so the traffic treated as unicast traffic as you said jen.
This is the result's capture, LAG still unbalanced

Re: LACP load balancing
Hello!
If you send one flow in each direction how do you expect to see a balancing? Internal hashing/balancing works on a flow basis. To make balancing statistically meaningful you have to send 100s of flows in one direction.
