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

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.
Key | Required | Choices | Description |
---|---|---|---|
ansible_host |
yes | Specifies the hostname or address for connecting to the remote device over the specified transport | |
ansible_port |
no | Specifies the port used to build the connection to the remote device; if value is unspecified, the ANSIBLE_REMOTE_PORT option is used; it defaults to 22 | |
ansible_ssh_user |
no | Specifies the username that authenticates the CLI login for the connection to the remote device; if value is unspecified, the ANSIBLE_REMOTE_USER environment variable value is used | |
ansible_ssh_pass |
no | Specifies the password that authenticates the connection to the remote device | |
ansible_become |
no | yes, no* | Instructs the module to enter privileged mode on the remote device before sending any commands; if value is unspecified, the ANSIBLE_BECOME environment variable value is used, and the device attempts to execute all commands in non-privileged mode |
ansible_become_method |
no | enable, sudo* | Instructs the module to allow the become method to be specified for handling privilege escalation; if value is unspecified, the ANSIBLE_BECOME_METHOD environment variable value is used |
ansible_become_pass |
no | Specifies the password to use if required to enter privileged mode on the remote device; if ansible_become is set to no this key is not applicable |
|
ansible_network_os |
yes | dellos6/dellos9/dellos10, null* | Loads the correct terminal and cliconf plugins to communicate with the remote device |
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.
