Note

This module is part of the dellemc.enterprise_sonic collection (version 2.5.1).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install dellemc.enterprise_sonic.

To use it in a playbook, specify: dellemc.enterprise_sonic.sonic_qos_interfaces.

New in dellemc.enterprise_sonic 2.5.0

Note

• Tested against Enterprise SONiC Distribution by Dell Technologies.

• Supports check_mode.

Return Values

Common return values are documented here, the following are the fields unique to this module:

Key	Description
after list / elements=string	The resulting configuration from module invocation. Returned: when changed, if check_mode is not set Sample: ["The configuration returned will always be in the same format as the parameters above.\n"]
after(generated) list / elements=string	The generated (simulated) configuration from module invocation. Returned: when check_mode Sample: ["The configuration returned will always be in the same format\n as the parameters above.\n"]
before list / elements=string	The configuration prior to the module invocation. Returned: always Sample: ["The configuration returned will always be in the same format as the parameters above.\n"]
commands list / elements=string	The set of commands pushed to the remote device. Returned: always Sample: ["command 1", "command 2", "command 3"]
