Fixed In Version:	nmstate-2.2.1-1.el9	Doc Type:	Enhancement
Doc Text:	.The `balance-slb` bonding mode is now supported The new `balance-slb` bonding mode Source load balancing requires no switch configuration. The `balance-slb` divides traffic on the source Ethernet address using `xmit_hash_policy`=`vlan+srcmac`, and NetworkManager adds necessary `nftables` rules for traffic filtering. As a result, you can now create bond profiles with the `balance-slb` option enabled by using NetworkManager.	Story Points:	---

Comment 1 Gris Ge 2022-11-03 06:34:32 UTC

Patch send to upstream: https://github.com/nmstate/nmstate/pull/2082

Example yaml:

```yml
---
interfaces:
- name: bond99
  type: bond
  state: up
  link-aggregation:
    mode: balance-xor
    options:
      xmit_hash_policy: "vlan+srcmac"
      balance-slb: 1
```



This is userspace bond option. You need updated NetworkManager, nftables and kernel. Nmstate only set `balanace-slb=1` to NM connection, not verifying its functionality. `nmcli c show` might indicate connection failed to activate due to errors of use space tools.

To test, checking output of `nmcli --fields bond.options c show <bond_conntion_id>` is enough.
