Unbalanced load in sharing using algorithm address-based L3_L4 LACP.

[Ambrose_Magee]

Hello,

On an X690-48x-2q-4c with EXOS 22.5.1.7-patch1-2, I have configured these commands.

enable sharing 19 grouping 19-20 algorithm address-based L3_L4 lacp

enable sharing 29 grouping 29-30 algorithm address-based L3_L4 lacp

Although the source and destination of the packets are several IP addresses, there is little load balancing.

30        A       10000    44.36         90.43         59.55          100.00

The Tx load is not balanced.  May I ask for suggestions to fix this, please?

Hi @Ambrose Magee, could you share the link to the KB you’re referencing here? Just in case another community member comes across the same situation you are seeing.

Hello Miguel,

Thank you for your support.  The root cause of the problem is traffic polarisation; there is a KB article on it.

Regards,

Hey,

How did you resolve it then ?
