Configuring Tunnel Interfaces

This section contains payload examples to demonstrate how to use the NX-API REST API to configure tunnel interfaces for the Cisco Nexus 3000 and 9000 Series switches.

Enabling Tunneling

Enabling Tunneling

POST http://<IP_Address>/api/node/mo/sys/fm.json

{
  "fmEntity": {
    "children": [
      {
        "fmTunnelif": {
          "attributes": {
            "adminSt": "enabled"
}}}]}}

{
    imdata:[]
}

<System>
  <fm-items>
    <tunnelif-items>
      <adminSt>enabled</adminSt>
    </tunnelif-items>
  </fm-items>
</System>

Enabling feature tunnel.

CLI Command

The CLI command below is the equivalent to the payload example displayed in the pane on the right. Click the DME tab in the top-left corner of the right pane to view the JSON payload or the YANG tab to view the XML payload.

feature tunnel

Note: The property information for this example was added in Release 9.3(3).

Verifying a DME Configuration
The following table contains the distinguished name (DN) for each managed object (MO) in the DME payload. Issue a GET request using the DN to verify the configuration was posted or to get information about the configured properties of a particular object.

MO	DN
fmEntity	sys/fm
fmTunnelif	sys/fm/tunnelif

fmTunnelif Properties

The following table contains information about the fmTunnelif properties in the DME payload. For more information about the properties and MOs, see the NX-API DME Model Reference linked in the Related Documentation section below.

Property Name	Data Type	Description	Values
adminSt	fm:AdminState (scalar:Enum8)	Admin status	SELECTION: 1 - enabled 2 - disabled DEFAULT: disabled
