The full configuration (equivalent to the CLI command admin display-config) can be retrieved using a <get-config> request:
when the <filter> tag is not present
For example:
<get-config>
<source>
<running/>
</source>
</get-config>
when only the <configure> tag is present inside a <filter> tag
For example:
<get-config>
<source>
<running/>
</source>
<filter>
<configure/>
</filter>
</get-config>
