Zimablade LACP with PCIe to 4-Port 2.5G Ethernet Adapter Realtek RTL8125B Chipset

Insight & Feedback

Hello,

I’m purchase zimablade with PCIe to 4-Port 2.5G Ethernet Adapter Realtek RTL8125B Chipset.
The current os use ZimaOS v1.5.3

How can i bundle two (2) port to become LACP ?

ZimaOS does not currently expose NIC bonding/LACP in the UI, and the OS is largely read-only. While your Realtek RTL8125B ports work as individual interfaces, bonding them via CLI is not supported, not persistent, and not recommended.

Key points:

  • Switch-side LACP alone will not work without OS-level bonding.
  • Each NIC can be used separately for services or isolation.
  • Advanced networking (bonding, VLANs, SMB multichannel) is not yet available.

I believe proper LACP needs native support in the ZimaOS network stack/UI.
If LACP is required now, I suggest handling bonding at the Proxmox/hypervisor level or using a single faster NIC (10G).

Thanks for the answer.
It is possible to do LACP if i revert back to CasaOS since its Debian based linux.

Short answer: Yes, it’s possible on CasaOS, but with caveats.

CasaOS is Debian-based, so Linux bonding (LACP 802.3ad) can be configured via CLI. However:

CasaOS does not officially support or manage LACP in its UI.

Configuration is manual, and updates or network changes can break or reset it.

You must also configure LACP on the switch.

I believe LACP is workable on CasaOS if you’re comfortable with Linux networking and accept the risk.
I suggest backing up first and treating it as an advanced, unsupported setup.

In contrast, ZimaOS currently does not support LACP at all, regardless of hardware.

Thanks for the feedback.
really appreciate it.

It’s nice if we can have LACP configuration for zimaos in future.
Hopefully Zima Team can make it.
