execute() Function (SLAX and XSLT)


SLAX Syntax

XSLT Syntax


Execute a remote procedure call (RPC) within the context of a specific management session in SLAX and XSLT automation scripts. Any number of RPCs may be executed within the same session until the session is closed with the jcs:close() function. This is in contrast to the jcs:invoke() function, which also performs RPC calls, but uses a unique session per command.


Python automation scripts can use Junos PyEZ APIs to execute RPCs on a local or remote device.



Connection handle generated by a call to the jcs:open() function.


Remote procedure call (RPC) to execute.

Return Value


Results of the executed RPC, which include the contents of the <rpc-reply> element, but not the <rpc-reply> tag itself. This $result variable is the same as that produced by the jcs:invoke() function. By default, the results are in XML format equivalent to the output produced with the | display xml option in the CLI.

Usage Examples

In the following example, the $rpc variable is declared and initialized with the Junos XML <get-interface-information> element. A call to the jcs:open() function generates a connection handle to the remote device at IP address The user’s login and password are provided as arguments to jcs:open() to provide access to the remote device. The code calls jcs:execute() and passes in the connection handle and RPC as arguments. Junos OS on the remote device processes the RPC and returns the results, which are stored in the $results variable.

The equivalent XSLT code is:
