Example: Generating a Custom Warning Message

Using a commit script, write a custom warning message that appears when the source-route statement is not included at the [edit chassis] hierarchy level. This example is the complete script for the sample <xnm:warning> element in Step item.

SLAX Syntax

ns junos = "http://xml.juniper.net/junos/*/junos";
ns xnm = "http://xml.juniper.net/xnm/1.1/xnm";
ns jcs = "http://xml.juniper.net/junos/commit-scripts/1.0";

Verifying the Commit Script Warning Output

To test the output of a warning message, make sure that the candidate configuration contains the condition that elicits the warning. For this example, ensure that the source-route statement is not included at the [edit chassis] hierarchy level.

To test the example in this chapter, perform the following steps:

Copy the XSLT script shown just previously into a text file, and name the file source-route.xsl.
Depending on whether you save your commit script files to the flash drive or the hard drive, copy the source-route.xsl file to the /config/scripts/commit or the /var/db/scripts/commit directory on your routing platform.
Include the file source-route.xsl statement at the [edit system scripts commit] hierarchy level:user@host> edit [edit] user@host# set system scripts commit file source-route.xsl
If the source-route statement is included at the [edit chassis] hierarchy level, issue the delete chassis source-route configuration mode command:[edit] user@host# delete chassis source-route
Issue the commit command.

When you issue the commit command, the following output appears:

    [edit]
    user@host# commit

    [edit chassis]
        warning: IP source-route processing is not enabled.
    commit complete

To display the Extensible Markup Language (XML) output of a warning message, issue the commit check | display xml command:

[edit]

user@host# commit check | display xml

<rpc-reply xmlns:junos="http://xml.juniper.net/junos/7.4R1/junos">
    <commit-results>
        <routing-engine junos:style="normal">
            <name>re0</name>
            <xnm:warning>
                <edit-path>
                    [edit chassis]
                </edit-path>
                <message>
                    IP source-route processing is not enabled.
                </message>
            </xnm:warning>
            <commit-check-success/>
        </routing-engine>
    </commit-results>
</rpc-reply>

To display a detailed trace of commit script processing, issue the commit check | display detail command:

[edit]

user@host# commit check | display detail
