Understanding Named Templates in Junos OS Automation Scripts

Junos OS provides several named templates that can be used in commit, op, event, and SNMP scripts to more easily accomplish scripting tasks on devices running Junos OS. The named templates reside in import files, which are included with the standard Junos OS installation available on switches, routers, and security devices running Junos OS. Table 1 summarizes the Junos OS named templates.

For information about using named templates in automation scripts, see Using Named Templates in Junos OS Automation Scripts.
