## Synopsis

- This module can be used to manage distributed switch Network IO Control configurations.

## Requirements

The below requirements are needed on the host that executes this module.

- python >= 2.6
- PyVmomi

## Parameters

Parameter | Choices/Defaults | Comments
--- | --- | ---
hostname string |  | The hostname or IP address of the vSphere vCenter or ESXi server. If the value is not specified in the task, the value of environment variable `VMWARE_HOST` will be used instead. Environment variable support added in Ansible 2.6.
password string |  | The password of the vSphere vCenter or ESXi server. If the value is not specified in the task, the value of environment variable `VMWARE_PASSWORD` will be used instead. Environment variable support added in Ansible 2.6. aliases: pass, pwd
port integer added in 2.5 | Default: 443 | The port number of the vSphere vCenter or ESXi server. If the value is not specified in the task, the value of environment variable `VMWARE_PORT` will be used instead. Environment variable support added in Ansible 2.6.
proxy_host string added in 2.9 |  | Address of a proxy that will receive all HTTPS requests and relay them. The format is a hostname or a IP. If the value is not specified in the task, the value of environment variable `VMWARE_PROXY_HOST` will be used instead. This feature depends on a version of pyvmomi greater than v6.7.1.2018.12
proxy_port integer added in 2.9 |  | Port of the HTTP proxy that will receive all HTTPS requests and relay them. If the value is not specified in the task, the value of environment variable `VMWARE_PROXY_PORT` will be used instead.

resources
list

List of dicts containing { name: Resource name is one of the following: "faultTolerance", "hbr", "iSCSI", "management", "nfs", "vdp", "virtualMachine", "vmotion", "vsan" limit: The maximum allowed usage for a traffic class belonging to this resource pool per host physical NIC. reservation: (Ignored if NIOC version is set to version2) Amount of bandwidth resource that is guaranteed available to the host infrastructure traffic class. If the utilization is less than the reservation, the extra bandwidth is used for other host infrastructure traffic class types. Reservation is not allowed to exceed the value of limit, if limit is set. Unit is Mbits/sec. shares_level: The allocation level ("low", "normal", "high", "custom"). The level is a simplified view of shares. Levels map to a pre-determined set of numeric values for shares. shares: Ignored unless shares_level is "custom". The number of shares allocated. reservation: Ignored unless version is "version3". Amount of bandwidth resource that is guaranteed available to the host infrastructure traffic class. }

state
string

Choices:
- present ←
- absent

Enable or disable NIOC on the distributed switch.

switch string / required |  | The name of the distributed switch. aliases: dvswitch
username string |  | The username of the vSphere vCenter or ESXi server. If the value is not specified in the task, the value of environment variable `VMWARE_USER` will be used instead. Environment variable support added in Ansible 2.6. aliases: admin, user

validate_certs
boolean

Choices:
- no
- yes ←

Allows connection when SSL certificates are not valid. Set to `false` when certificates are not trusted.
If the value is not specified in the task, the value of environment variable `VMWARE_VALIDATE_CERTS` will be used instead.
Environment variable support added in Ansible 2.6.
If set to `yes`, please make sure Python >= 2.7.9 is installed on the given machine.

version
string

Choices:
- version2
- version3

Network IO control version.

## Notes

Note

- Tested on vSphere 6.7

## Examples

    - name: Enable NIOC
      vmware_dvswitch_nioc:
        hostname: '{{ vcenter_hostname }}'
        username: '{{ vcenter_username }}'
        password: '{{ vcenter_password }}'
        switch: dvSwitch
        version: version3
        resources:
            - name: vmotion
              limit: -1
              reservation: 128
              shares_level: normal
            - name: vsan

              shares_level: custom
              shares: 99
              reservation: 256
        state: present
      delegate_to: localhost

    - name: Disable NIOC
      vmware_dvswitch_nioc:
        hostname: '{{ vcenter_hostname }}'

        password: '{{ vcenter_password }}'
        switch: dvSwitch
        state: absent
      delegate_to: localhost
