changing native_vlan in nxos_l2_interfaces using mode trunk removes mode trunk

[aj-cruz]

SUMMARY

If I have a trunk interface defined with a native vlan, then I set the native vlan to the default native vlan 1 and run the playbook, the interface mode trunk is removed.

STEPS TO REPRODUCE

- name: Configure L2 Interface Properties
  cisco.nxos.nxos_l2_interfaces:
    config:
      - name: Ethernet1/5
        mode: trunk
        trunk:
          native_vlan: 10
    state: overridden

changed to:

- name: Configure L2 Interface Properties
  cisco.nxos.nxos_l2_interfaces:
    config:
      - name: Ethernet1/5
        mode: trunk
        trunk:
          native_vlan: 1
    state: overridden

EXPECTED RESULTS

Running the playbook the first time should produce this configuration:

interface Ethernet1/5
  switchport mode trunk
  switchport trunk native vlan 10

Subsequent run with native vlan set to 1 should produce this configuration:

interface Ethernet1/5
  switchport mode trunk

ACTUAL RESULTS

Subsequent run with native vlan changed to 1 produces this configuration:

interface Ethernet1/5

switchport mode trunk is removed.
