Customer wants to connect manually a device interface with another one without using discover connections, but for some interfaces this option is disabled (grayed out). How to make it enable again?


Release : 21.2.x, 22.2.x


In topo-app-config.xml file there is a filter that tests if the model _class of interface is a Port(15) if the interface has a different model_type the Start Connection is grayed out.


Edit the $SPECROOT/tomcat/webapps/spectrum/WEB-INF/topo/config/topo-app-config.xml and remove or comment out the filter for the manage-pipes privilege  (after line 2350) as below (lines in green) :

    <item name="">
                Collects by Universe 
              <can-be-related mtypeID="0x10091">0x10002</can-be-related>
            <model-class>15</model-class>  Port 
               No LMT-related model types 
              <attribute-list id="AttributeID.MTYPE_HANDLE">

 save and then re-open OC console.

Additional Information

The default SPECROOT/tomcat/webapps/spectrum/WEB-INF/topo/config/topo-app-config.xml file must be edited for this to work. It will not work by copying the topo-app-config.xml file to the $SPECROOT/custom/topo/config directory and then editing that file.

Since this is a modification to an out of the box default file an upgrade of Spectrum may overwrite this file.
