Environment

VMware Smart Assurance - NCM

Cause

This is because the term-priv mode is set to enabled in the stdjuniperpush.inc file as follows:

MECHANISM = mechanism;

        if(contType=="termlet"){
            if (destName == "termlet-user") {
                stdPushTermlet(cfgFile.Content, configFileTermletDisabled,setInstruction.ViaModem, "set cli screen-length 0"+stdEOL);
                retVal = daslSuccess;
            }
            else if (destName=="termlet-priv") {
                stdPushTermlet(cfgFile.Content, configFileTermletEnabled,setInstruction.ViaModem, "set cli screen-length 0"+stdEOL);
                retVal = daslSuccess;
            }

when it should be using the User Mode 

Resolution

Alter the configFileTermletEnabled to configFileTermletDisabled as follows:

1. mkdir ../smarts-ncm/custompackage/juniper if it doesn't exist already 
2. cp ../smarts-ncm/package/juniper/stdjuniperpush.inc to ../smarts-ncm/custompackage/juniper/stdjuniperpush.inc
3. edit the ../smarts-ncm/custompackage/juniper/stdjuniperpush.inc file and change the line mentioned above:

stdPushTermlet(cfgFile.Content, configFileTermletEnabled,setInstruction.ViaModem, "set cli screen-length 0"+stdEOL) as follows: 

MECHANISM = mechanism;

        if(contType=="termlet"){
            if (destName == "termlet-user") {
                stdPushTermlet(cfgFile.Content, configFileTermletDisabled,setInstruction.ViaModem, "set cli screen-length 0"+stdEOL);
                retVal = daslSuccess;
            }
            else if (destName=="termlet-priv") {
                stdPushTermlet(cfgFile.Content, configFileTermletDisabled,setInstruction.ViaModem, "set cli screen-length 0"+stdEOL);
                retVal = daslSuccess;
            }

4. Save and close the file 
5. Restart the voyence services

This will default the termlet to use User Mode.
