This role facilitates the configuration of a prefix-list. It supports the configuration of an IP prefix-list, and assigns the prefix-list to line terminals. This role is abstracted for dellos9 and dellos10.

The prefix-list role requires an SSH connection for connectivity to a Dell EMC Networking device. You can use any of the built-in OS connection variables.

ansible-galaxy install Dell-Networking.dellos-prefix-list

• Role is abstracted using the ansible_network_os variable that can take dellos9 and dellos10 values
• If dellos_cfg_generate set to true, the variable generates the role configuration commands in a file
• Any role variable with a corresponding state variable set to absent negates the configuration of that variable
• Setting an empty value for any variable negates the corresponding configuration
• Variables and values are case-sensitive

dellos_prefixlist keys

NOTE: Asterisk (*) denotes the default value if none is specified.

Ansible Dell EMC Networking roles require connection information to establish communication with the nodes in your inventory. This information can exist in the Ansible group_vars or host_vars directories, or inventory or in the playbook itself.

NOTE: Asterisk (*) denotes the default value if none is specified.

The dellos-prefix-list role is built on modules included in the core Ansible code. These modules were added in Ansible version 2.2.0.

This example uses the dellos-prefix-list role to configure prefix-list for both IPv4 and IPv6. It creates a hosts file with the switch details and corresponding variables. The hosts file should define the ansible_network_os variable with corresponding Dell EMC networking OS name.

When dellos_cfg_generate is set to true, the variable generates the configuration commands as a .part file in build_dir path. By default, the variable is set to false. It writes a simple playbook that only references the dellos-prefix-list role.
