The issue occurred during updating a LAG port on its port details page:

1. Switch off 'Discovery Packets' toggle:
   Request details:

PUT /openkilda/api/switch/00:00:00:22:3d:5a:04:87/ports/2496/properties
body: 
{
  "discovery_enabled": false
}

Response:

{
    "error-code": 1390412,
    "error-message": "Object was not found",
    "error-auxiliary-message": "Port not found: 'Port FSM not found (00:00:00:22:3d:5a:04:87_2496).'",
    "correlation_id": "",
    "error-description": "Port not found exception"
}

Note, issue occurred on both virtual and hardware environments.
2. Update port status and try to save changes:
Request details:

PUT /openkilda/api/switch/00:00:00:00:00:00:00:08/2198/config
body: 
{
  "status": "UP"
}

Response:

{
    "error-code": 1390412,
    "error-message": "Invalid request data",
    "error-auxiliary-message": "Unable to get port by number 2198 on the switch 00:00:00:00:00:00:00:08",
    "correlation_id": "",
    "error-description": "Port configuration request failed"
}

Note, the 2nd issue (updating port status) has been caught only on virtual environment.
