This playbook demonstrates how to install the minimum SNMPv3 configuration on a Junos device.

To run, update credentials in group_vars/all.yml, list of hosts in site.yml, and execute:

ansible-playbook -i hosts site.yml

A diff of the config will be saved for each device with a timestamp.

To test your device you can install snmp and run:

sudo apt install snmp
snmpget -v3 -u mysecretv3username -l authPriv \
-a MD5 -A mysecretv3password -x AES \
-X mysecretv3password <DEVICE IP> \
1.3.6.1.2.1.1.1.0

This playbook deploys the config safely to the device by first showing you the diff without committing the changes and giving you the option to continue or abort. Then it will perform a commit confirm, check to see the device is still reachable, and then issue the final commit. The SNMP credentials that you provide are stored temporarily in a temp directory and cleaned up immediately after each communication to the device has completed.

Lastly, there is an additional role that is responsible for adding the device to Junos Space via the REST API. If you want to skip this run the playbook with the skip-tags argument for space and these tasks will be skipped. Example below:

ansible-playbook -i hosts --skip-tags space site.yml

NOTE: If planning on running playbooks in Ansible Tower vars_prompt should be removed. Set variables in group_vars/all.yml instead and fill out in Tower
