refresh-from (SNMP Scripts)


Hierarchy Level


Overwrite the local copy of all enabled SNMP scripts or a single enabled SNMP script with the copy located at the specified URL. If the load-scripts-from-flash statement is configured, the device refreshes the scripts on the flash drive instead of the hard drive.

The update operation occurs as soon as you issue the set refresh-from url configuration mode command. Issuing the set refresh-from command does not add the refresh-from statement to the configuration. Thus, the command behaves like an operational mode command by executing an operation, instead of adding a statement to the configuration.

Before you refresh a local script from an HTTPS server, you must first configure the cert-file statement for that script in supported releases. Specify the absolute path to the certificate (Root CA or self-signed) that the device will use to validate the server's certificate during the refresh operation.


This statement is not supported on the QFabric system.

As of Junos OS Release 18.1R1, you can specify which routing instance the update is done through. To specify the routing instance to use for updating snmp scripts, configure the routing instance in two places in the CLI:

If you enable the non-default management instance and use mgmt_junos for routing-instance-name, you can configure scripts to update using the dedicated management instance mgmt_junos.



The source specified as an HTTPS URL, HTTP URL, FTP URL, or secure copy (scp)-style remote file specification.
