Devices running on EOS 4.23.4M and 4.25.4M experience the problem (probably more version are impacted)

STEPS TO REPRODUCE

When you run a task to replace the configuration which contains the following lines (while not in the running config yet) the task will time out:

!
interface defaults
   ethernet
      shutdown
!

I'm using the following task:

- name: replace configuration with intended configuration
  eos_config:
    src: 'config-switch.cfg'
    backup: no
    replace: config
    save_when: modified

I'm using the ssh connection (not eapi).

EXPECTED RESULTS

I'm expecting the configuration to be installed and activated.

ACTUAL RESULTS

The task is not executed because it times out.

The full traceback is:
  File "/tmp/ansible_eos_config_payload__bslaava/ansible_eos_config_payload.zip/ansible/module_utils/network/eos/eos.py", line 174, in load_config

        }
    },
    "msg": "timeout value 30 seconds reached while trying to send command: b'shutdown'"
}

This is probably triggered becouse EOS is asking for extra input that is not in the configuration file see a short screen capture:

TL-SW-LF001#configure session test
TL-SW-LF001(config-s-test)#interface defaults
TL-SW-LF001(config-s-test-interface-defaults)#ethernet
TL-SW-LF001(config-s-test-interface-defaults-ethernet)#shutdown
! This command will change the administrative status of every Ethernet interface that has not yet been specifically configured.
This might include the interface over which this session runs!
Here is the list of affected interfaces:
Et1 Et2 Et3 Et4 Et5 Et6 Et7 Et8

Do you wish to proceed with this command?[yes/no]:

This is not an issue when using ansible_connection: ansible.netcommon.httpapi

Hi @daanvdsanden Thank you for submitting this issue. Can I suggest you try eos_command module with prompt handling, instead of eos_config ? You can get more information on how to use eos_command for this purpose from this description.

kdam0 commented 6 months ago

@GomathiselviS even when using the eos_command module I seem to trigger the timeout error message.

I used the exact example from the docs:

- name: run a command that requires a confirmation. Note that prompt
    takes regexes, and so strings containing characters like brackets
    need to be escaped.
  arista.eos.eos_command:
    commands:
      - command: reload power
        prompt: \[confirm\]
        answer: y
        newline: false
