15	    We want to ensure that the interface setup as iso
16	    has mpls enabled. If it is not enabled the script makes it so.
17	  </description>
18	  <implementation>
19	    For every logical unit with iso enabled, we test to see if
20	    mpls is enabled.  If it isn't, we call jcs:emit-change()
21	    to add it for us.
