• Bug Report

COMPONENT NAME

ios_command

ANSIBLE VERSION

ansible 2.10.4
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/home/murmanov/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /home/murmanov/.local/lib/python3.7/site-packages/ansible
  executable location = /home/murmanov/.local/bin/ansible
  python version = 3.7.9 (default, Aug 18 2020, 06:22:45) [GCC 7.5.0]

CONFIGURATION

murmanov@pynengvm:~$ ansible-config dump --only-changed
HOST_KEY_CHECKING(/etc/ansible/ansible.cfg) = False
INTERPRETER_PYTHON(/etc/ansible/ansible.cfg) = /usr/bin/python3
PERSISTENT_COMMAND_TIMEOUT(/etc/ansible/ansible.cfg) = 180
PERSISTENT_CONNECT_TIMEOUT(/etc/ansible/ansible.cfg) = 180

OS / ENVIRONMENT

Device: WS-C2960X-48TD-L Software version: 15.2(2)E7

STEPS TO REPRODUCE

- name: "ACL configuration"
  hosts: lgb3-ios-mgmt
  gather_facts: no

  tasks:

    - name: Configure length
      ios_config:
        lines:
          - length 48
        before: line vty 0 15
        save_when: changed
        diff_against: running

EXPECTED RESULTS

The expected result to have terminal length configured under line vty 0 15

ACTUAL RESULTS

Tried to use ios_command lines and src in both situations I see that command has been pasted to the device, however task hangs forever
