Description

Add ability to set overlay network via the dcnm_interface module. Currently you can only set VLANs, etc., but cannot move interfaces between overlay networks.

New or Affected modules(s):

• dcnm_interface

DCNM version

Using NDFC

• V 2.2(2d)

Potential ansible task config

- name: Change overlay network on interface
  cisco.dcnm.dcnm_interface:
    fabric: test-fabric
    state: merge
    config:
      - name: Ethernet1/10
        type: eth
        switch:
          - "testswitch1"
        deploy: true
        profile:
          mode: eth
          int_vrf: ""
          overlay_network: "Test Overlay"
          cmds:
            - no shutdown

@domainzero Thanks for opening this request. I need to look into how we might approach this.

Hi @domainzero we did some investigation and it seems like you could accomplish what you want using the dcnm_network module. The attach: ports property allows you to associate an interface with a particular network.

For example:

- name: Merge networks
  cisco.dcnm.dcnm_network:
    fabric: vxlan-fabric
    state: merged
    config:
    - net_name: "Test_Overlay"
      vrf_name: Tenant-1
      net_id: 7005
      vlan_id: 150
      gw_ip_subnet: '192.168.30.1/24'
      attach:
      - ip_address: testswitch1
        ports: [Ethernet1/10]
      deploy: true

Will this work for your use case?

This will probably work for our use case. We're essentially trying to follow this whitepaper using NDFC + overlay networks instead of NX-OS directly and VLAN tags, etc.
