Hello all,

I’ve just started to play with Ansible.When I run playbook which should create int Vlan, the Vlan is created but the playbook ends with errors.

tasks:

- name: Create interface  
nxos\_interface:  
interface: Vlan50

When I run the same playbook with other interface type (Ethernet, Loopback) it ends normaly.
