Hi Karthik,

The other_config is not supported at interface level yet.

Could you provide expected output of `sudo ovs-vsctl list port`?

Meanwhile, could you provide use case for us to plan this new feature?

Thank you!

The ovs-bond has certain parameters that needs to be configured via other-config [1].

The expected output for ovs-bond would be

[root@dell-r640-oss-14 ~]# sudo ovs-vsctl list port

Also its required for Bridges Table, as we have a need to set the "other_config : mac-table-size" for the bridge.
So IMHO the ovs-db object shall be present at global level, bridge level and port level. The BZ description needs this refinement.

The `other_config` is supported at global level.

This bug will be used for tacking the effort at interface level(OVS bridge and OVS bond).

Patch posted to upstream: https://github.com/nmstate/nmstate/pull/2195

Example on `other_config` of OVS bridge:

```yml
interfaces:
- name: br0
  type: ovs-bridge
  state: up
  ovs-db:
    other_config:
      in-band-queue: '12'
  bridge:
    port:
    - name: eth1
    - name: ovs0
```

Example on `other_config` of OVS Bond:

```yml
- name: br0
  type: ovs-bridge
  state: up
  bridge:
    port:
    - name: bond1
      link-aggregation:
        mode: balance-slb
        ovs-db:
          other_config:
            bond-miimon-interval: "100"
        port:
          - name: eth2
          - name: eth1
```

Example on `other_config` of OVS interface:

```yml
- name: eth1
  type: ethernet
  state: up
  ovs-db:
    other_config:
      emc-insert-inv-prob: 90
```

Can you please also include the example usage for DPDK ports.

Hi Karthik Sundaravel,

Could you show me the output of `sudo ovs-vsctl list port` and `sudo ovs-vsctl list interface` for DPDK `other_config`?

I failed to any any valid `other_config` for DPDK in manpage of `ovs-vswitchd.conf.db`.

A typical use case for DPDK is

ovs-vsctl set interface dpdk-p0 options:n_rxq=4 other_config:pmd-rxq-affinity="0:3,1:7,3:8"

The output of `sudo ovs-vsctl list interface` is given below.

Hi Karthik,
