execute() Function (SLAX and XSLT)
date_range
10-Feb-22
Namespaces
content_copy zoom_out_map
http://xml.juniper.net/junos/commit-scripts/1.0
SLAX Syntax
content_copy zoom_out_map
var $result = jcs:execute(connection, rpc);
XSLT Syntax
content_copy zoom_out_map
<xsl:variable name="result" select="jcs:execute(connection, rpc)"/>
Description
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.
Note:
Python automation scripts can use Junos PyEZ APIs to execute RPCs on a local or remote device.
Parameters
connection | Connection handle generated by a call
to the |
rpc | Remote procedure call (RPC) to execute. |
Return Value
result | Results of the executed RPC, which include the contents
of the |
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 198.51.100.1. 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.
content_copy zoom_out_map
var $rpc = <get-interface-information>;
var $connection = jcs:open('198.51.100.1', 'bsmith', 'test123');
var $results = jcs:execute($connection, $rpc);
expr $results;
expr jcs:close($connection);The equivalent XSLT code is:
content_copy zoom_out_map
<xsl:variable name="connection" select="jcs:open('198.51.100.1', 'bsmith', 'test123')"/>
<xsl:variable name="rpc">
<get-interface-information/>
</xsl:variable>
<xsl:variable name="results" select="jcs:execute($connection, $rpc)"/>
<xsl:value-of select="$results"/>
<xsl:value-of select="jcs:close($connection)"/>
