Why I can't change the administrative state of a port on cisco apic via rest API - rest

Question

When I try to change the administrative state of a port on the Cisco APIC via rest API (aci_rest) then I'm getting the following error :
"msg": "APIC Error 170: Invalid access, MO: l1PhysIf",
"status": -1
Does anyone have any idea about that?
Thanks in advance.
- name: Change admin state of the port
aci_rest:
hostname: "{{ inventory_hostname }}"
username: "{{ aci_user }}"
password: "{{ aci_password }}"
validate_certs: no
path: "/api/node/mo/topology/pod-{{ pod_id }}/node-{{ node_id }}/sys/phys-[eth{{ interface }}].json"
method: post
content:
{
"l1PhysIf": {
"attributes": {
"adminSt":"down",
}
}
}

Answer 1

I've solved the problem. Cisco has restricted "l1PhysIf" object and there is documentation which looks like:
Class l1: PhysIf (CONCRETE)
Class ID:3627
Class Label: Layer 1 Physical Interface Configuration
Encrypted: false - Exportable: false - Persistent: true - Configurable: false - Subject to Quota: Disabled - Abstraction Layer: Concrete Model - APIC NX Processing: Disabled
Write Access: [NON CONFIGURABLE]
I've used "fabricRsOosPath" instead and it has worked.

Answer 2

Same thing here, but just trying to add a description. I get locking down a physical port object. Kinda. But a description?
The class mentioned above doesn't have any attribs that apply to a port description. Anyone have success at this?
I'm currently just using Postman to test, but will eventually throw this into python
API Post (port 10 for example):
https://{{url}}/api/node/mo/topology/pod-1/node-101/sys/phys-[eth1/10].json
JSON body:
{
"l1PhysIf":{
"attributes":{
"descr": "CHANGED"
}
}
}
Response: 400 Bad Request
{
"error": {
"attributes": {
"code": "170",
"text": "Invalid access, MO: l1PhysIf"
}
}
}
