Enabling and Disabling Interfaces

Objectives

After completing this section, you should be able to use Ansible to enable and disable interfaces on a network device.

Selecting an Interface Module

What are the differences between the *os_interface and *os_l3_interface modules?

The *os_l3_interface module:
- Manages IPv4 and IPv6 layer 3 addresses; it maps layer 3 addresses to interfaces.
- Can map IPv4 or IPv6 addresses to interfaces explicitly; it can also map both IPv4 and IPv6 explicitly by field name at the same time.
- Supports the aggregate argument, which takes as an argument a dictionary with name and layer 3 address fields.
The *os_interface module is used for managing all other aspects of network interfaces, including descriptions and enabling and disabling interfaces.
