Rules and Notes

To configure a CUPS solution, perform the following steps:

S.No	Steps	Refer to..
1.	Creating Inventory Directory	Creating Inventory Directory
2.	Creating fmInfo.yml	Creating fmInfo.yml
3.	Creating ansible_inputs.json	Creating ansible_inputs.json
4.	Creating CUPS inventory file	Creating CUPS inventory file
5.	Creating host_vars directory	Creating host_vars directory
6.	Creating host_vars files	Creating host_vars files

Creating Inventory Directory

Create an Inventory Directory to store all the CUPS related configuration files.

Copy

username@fmreg26:~$ mkdir cupsSolution
username@fmreg26:~$ ls -l
drwxr-xr-x 2 ddaniel fmtaf 4096 May 11 11:59 cupsSolution

Creating CUPS inventory file

Create the mobility_inventory file inside Inventory Directory.

gigamon@fmreg26:~/cupsSolution$ touch mobility_inventory

gigamon@fmreg26:~/cupsSolution$ ls -l

-rw-r--r-- 1 gigamon fmtaf 355 May 11 12:24 ansible_inputs.json

-rw-r--r-- 1 gigamon fmtaf 396 May 11 14:22 mobility_inventory

-rw-r--r-- 1 gigamon fmtaf 172 May 11 12:10 fmInfo.yml

The file contains the details of the following groups and provide the inputs to the groups as shown in the following table:

S.No	Groups-Input
Note: —You can provide the input or leave the field empty if you don't want to use the playbook to configure the following groups.
1.	Ports—Name of the Cluster or standalone device IP that contains the ports that need to be configured.
2.	IPInterfaceSolution—Name of the Cluster or standalone device IP on which the IPInterfacesolution needs to be configured.
3.	Tool Groups—Name of the Cluster or standalone device IP on which the Tool Group needs to be configured.
4.	Gigastreams—Name of the Cluster or standalone device IP on which the Gigastreams needs to be configured.
5.	GTPWhitelist—Name of the Cluster or standalone device IP on which the GTPWhitelist Data Base needs to be configured.
6.	Policies—Name of the Global policy or policies.
7.	GTP— Name of the GTP node or nodes.
6.	CPN—Name of the CPN or CPNs.
7.	UPN—Name of the UPN or UPNs.
8.	SAM—Name of SAM Exporter node or nodes.
9.	Sites—Name of the site or sites and the names of the CPN/UPN participating in the site or sites.
10.	CUPS—Name of the file CUPS solution along with lts_policy file name, 5g_policy file name, lte_policy file name and list of sites participating in the CUPS solution

Creating host_vars files

Every unique element under each group in the mobility_inventory file needs to have a file, with the same name as the element, inside host_vars directory. This file has properties of the groups that it belongs to.

Below are the templates of various host_vars files.

Deployment of CUPS Solution

To deploy the CUPS solution, follow these steps:

To remove the CUPS solution, follow these steps:

■

Execute the playbook and use the following command:

/usr/local/bin/ansible-playbook -e '@~/<Path to Inventory directory>/ansible_inputs.json' -i ~/<Path to Inventory directory>/mobility_inventory /<Path to Ansible playbook>/delete_mobility_solution.yml

Note: The multiple YML files created inside the host_vars are concatenated, converted into JSON format and sent to GigaVUE-FM.
