LACP load balancing algorithm

L0 Member

Hello Team,


Where I can find information about how traffic balance between physical interfaces in case when LACP used?

Can I choose balancing method in configuration (source/destination, MAC/IP Addr, L4 Ports)?


I found information about traffic distribution mechanism in LAG for early versions of software (prior 6.1😞
But there is no info in case when LACP using.




Hi @VPenkivskyi ,

LACP support was introduced in verion 6.1 and haven't change since (at least from what I know). So this document is still valid.

Which means if all interfaces in the group have equal priority firewall will use the last three bits from the session ID and use it as hash value.  I think this comment gives more details -
