load balancing lacp

Question

Computer networks

Greetings!

I have two J8773A switches. I set up a lacp of 4 ports between them
. Unfortunately, the traffic is not distributed evenly over the links - if 2 3 4, it didn’t go anywhere else, then the 1st is almost 4 times higher than the others.

I think that the problem is in load balancing - I once had a similar problem on cisco, I solved it there by setting the balancing.

But I can't find how to configure it in this series of switches

# show version
L.11.24

There is also this

# show trunks
Load Balancing

Port | name type | Group Type
- + - --------- + - -----

In one of the articles in Google, I found the output of this command as follows:

# show trunks
Load Balancing Method: L3-based (Default), L2-based if non-IP traffic

Knowledgeable people please help

Answer 1

Please provide your configuration of the op part of the interface and VLAN settings.

Answer 2

I believe that you do not have enough IP-source IP-destination pairs to fully load all the links. One IP source and one IP destination, in one TCP session, most likely will not use more than one physical link in the etherchannel (trunk).

Answer 3

Most likely in this switch it is impossible to configure the balancing algorithm. I also faced such a problem, the only solution is to change the switches.

Answer 4

What happens if you disable the first link? What if there is such a crazy hashing method that the load on the rest of the links will even out?
