sFlow role
|
|
==========
|
|
|
|
This role facilitates the configuration of global and interface level sFlow attributes. It supports the configuration of sFlow collectors at the global level, enable/disable, and specification of sFlow polling-interval, sample-rate, max-datagram size, and so on are supported at the interface and global level. This role is abstracted for Dell EMC platforms running OS9.
|
|
|
|
The os9_sflow role requires an SSH connection for connectivity to a Dell EMC Networking device. You can use any of the built-in OS connection variables.
|
|
|
|
|
|
Role variables
|
|
--------------
|
|
|
|
- Role is abstracted using the *ansible_network_os* variable that can take the dellemc.os9.os9 as a value
|
|
- If *os9_cfg_generate* is 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
|
|
- *os9_sflow* (dictionary) contains keys along with *interface name* (dictionary)
|
|
- Interface name can correspond to any of the valid os9 physical interfaces with the unique interface identifier name
|
|
- Interface name must be in *<interfacename> <tuple>* format; physical interface name can be in *fortyGigE 1/1* format for os9 devices
|
|
- Variables and values are case-sensitive
|

Connection variables
|
|
--------------------
|
|
|
|
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 | os9, null\* | This value is used to load the correct terminal and cliconf plugins to communicate with the remote device. |
|
|
|
|
> **NOTE**: Asterisk (\*) denotes the default value if none is specified.
|
|
|
|
Dependencies
|
|
------------
|
|
|
|
The *os9_sflow* role is built on modules included in the core Ansible code. These modules were added in Ansible version 2.2.0.
|
|
|
|
Example playbook
|
|
----------------
|
|
|
|
This example uses the *os9_sflow* role to configure sFlow attributes at interface and global level. It creates a *hosts* file with the switch details and corresponding variables. The hosts file should define the *ansible_network_os* variable with the corresponding Dell EMC networking OS name.
|
|
|
|
When *os9_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 *os9_sflow* role. By including the role, you automatically get access to all of the tasks to configure sFlow features.
