Products

• VMware Smart Assurance
• Network Observability

Issue/Introduction

• Device model is populated with SysOID instead of actual model entry.
• Device Model Name in the NCM console does not match the model name from device. 
• Wrong model populated in GUI for device. 
• Temporary certification explained with Cisco vendor.

Environment

All supported NCM versions 

Resolution

The following changes will need to be made on each device server (DS) and/or combination server (CS). Always set the environmental variable as source /etc/voyence.conf

1. If cisco directory does not exist already, create in the custompackage directory as follows:
   

   mkdir $VOYENCE_HOME/custompackage/cisco/

2. If Cisco directory does not exist already, create in the custompackage/pkgxml directory as follows:
   

   mkdir $VOYENCE_HOME/custompackage/pkgxml/Cisco/

    
3. If Cisco.models file does not already exist, create in the the custompackage/cisco directory as follows:
   

   cp $VOYENCE_HOME/package/cisco/Cisco.models  $VOYENCE_HOME/custompackage/cisco/Cisco.models

    
4. Add the following line to the bottom of the list in $VOYENCE_HOME/custompackage/cisco/Cisco.models:
   Model Name;                    SysOID;                Driver;                  Model Name Alternate
881;                           1.837;                    1
   Where 1st entry is Model, 2nd is OID excluding EnterpriseID of Cisco and 3rd is packageID.
    
5. Save and close the Cisco.models file.
    
6. Run the $VOYENCE_HOME/tools/mkmodelsxml.pl perl script as follows:
   

   $VOYENCE_HOME/tools/mkmodelsxml.pl < $VOYENCE_HOME/custompackage/cisco/Cisco.models > $VOYENCE_HOME/custompackage/pkgxml/Cisco/CiscoModels.xml

   NOTE: The variable $VOYENCE_HOME refers to the installed location of NCM.
