Deleting a network interface from a virtual machine

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

1. View the description of the CLI command for deleting a network interface from a virtual machine:

   yc compute instance detach-network-interface --help
   

2. Get a list of VMs in the default folder:

   yc compute instance list
   

   Result:

   +----------------------+-----------------+---------------+---------+----------------------+
   |          ID          |       NAME      |    ZONE ID    | STATUS  |     DESCRIPTION      |
   +----------------------+-----------------+---------------+---------+----------------------+
   | fhm0b28lgfp4******** | first-instance  | ru-central1-a | RUNNING | my first vm via CLI  |
   | fhm9gk85nj7g******** | second-instance | ru-central1-a | RUNNING | my second vm via CLI |
   +----------------------+-----------------+---------------+---------+----------------------+
   

   Save the ID of the VM from which you want to delete a network interface.

3. Stop the selected VM, if required, by specifying its ID:

   Note

   The feature of adding and removing network interfaces on running VMs is at the Preview stage. To access the feature, contact support.

   yc compute instance stop <VM_ID>
   

4. Get a list of network interfaces for the selected VM by specifying its ID:

   yc compute instance get <VM_ID>
   

   Result:

   ...
   network_interfaces:
     - index: "0"
       mac_address: d0:0d:1a:**:**:**
       subnet_id: e2lrucutusnd********
       primary_v4_address:
         address: 192.168.1.20
         one_to_one_nat:
           address: 158.***.**.***
           ip_version: IPV4
       security_group_ids:
         - enpuatgvejtn********
     - index: "1"
       mac_address: d0:1d:1a:**:**:**
       subnet_id: e2lpp96bvvgp********
       primary_v4_address:
         address: 192.168.2.3
       security_group_ids:
         - enpuatgvejtn********
         - enpg8d2hqh1o********
     - index: "2"
       mac_address: d0:2d:1a:**:**:**
       subnet_id: e2lv9c6aek1d********
       primary_v4_address:
         address: 192.168.4.17
       security_group_ids:
         - enpuatgvejtn********
         - enpg8d2hqh1o********
   ...
   

   Save the number (the index field value) of the network interface you want to delete.

5. Delete the network interface:

   yc compute instance detach-network-interface \
     --id <VM_ID> \
     --network-interface-index <network_interface_number>
   

   Where:

   • --id: ID of the selected VM. Instead of an ID, you can use the --name parameter to specify the VM name.
   • --network-interface-index: Previously saved number of the VM's network interface you want to delete.

   Result:

   ...
   network_interfaces:
     - index: "0"
       mac_address: d0:0d:1a:**:**:**
       subnet_id: e2lrucutusnd********
