This role facilitates the configuration of link aggregation group (LAG) attributes, and supports the creation and deletion of a LAG and its member ports. It also supports the configuration of an interface type as a static or dynamic LAG, hash scheme in dellos6 devices, and minimum required link. This role is abstracted for dellos9, dellos6, and dellos10 devices.
The LAG 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-lag
- Object drives the tasks in this role
- dellos_lag (dictionary) contains the hostname (dictionary)
- Hostname is the value of the hostname variable that corresponds to the name of the OS device
- Role is abstracted using the ansible_network_os variable that can take dellos6, dellos9, and dellos10 values
- Any role variable with a corresponding state variable setting to absent negates the configuration of that variable
- Setting an empty value to any variable negates the corresponding configuration
- dellos_lag (dictionary) holds a dictionary with the port-channel ID key in
Po <ID>
format (1 to 4096 for dellos9; 1 to 128 for dellos10 and dellos6) - 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-lag 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-lag role to setup port channel ID and description, and configures hash algorithm and minimum links for the LAG. Channel members can be configured for the port-channel either in static or dynamic mode. You can also delete the LAG with the port-channel ID or delete the members associated to it. This example 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-lag role.
