I would like to implement LACP on the infiniband switch Mellanox MLNX-OS MSB7800 as it is explained on: https://enterprise-support.nvidia.com/s/article/howto-configure-lacp-on-mellanox-switches but the os command: “LACP” doesn’t exist in the switch. Could you tell me if it is possible? and how to implement it?
The current firmware on the swith is: X86_64 3.9.2400 2021-03-24 14:34:04 x86_64
Thank you in advance for your reply.
No LACP for Infiniband. You are looking at an Ethernet related post.
HI @dwaxman , thank you for your reply. However here is explained how to implement bonding with infiniband networks: https://enterprise-support.nvidia.com/s/article/howto-create-linux-bond–lag–interface-over-infiniband-network. Is that possible just from the server side? thank you in advance.
Yes – this is IPoIB bond that is done for high availability.
It doesn’t allow for active/active configuration that’ll work using LACP towards the switch etc.
Thank you @dwaxman for your reply.
We just have an additional question for you: Is there any bonding policy that we should use to implement it?
If you mean to use LACP in IB – it is not possible to do that.
As stated in the doc you referred to, IPoIB bond mode is only for active/backup (bonding mode number 1, or “active-backup”) – hence not requiring anything on the switch configuration.
