Interface alarms are not getting created for specific Juniper devices.

Products

• VMware Smart Assurance
• Network Observability

Issue/Introduction

Symptoms:

• Interface alarms are not getting created as interface is not discovered and hence not monitored. 
• Required interfaces are not discovered for SysOID .1.3.6.1.4.1.2636.1.1.1.4.82.17
• Modification to tpmgr-param.conf does not work.
• Some interfaces are not being discovered in Smarts.
• Interfaces without configured IP address are not discovered.

Environment

All Supported Smarts releases

Cause

IFTypePattern would work only if interface extension driver is available.

Resolution

1. Navigate to <IP_BASE>/smarts/bin
2. Run ./sm_edit conf/discovery/DISCOVERY_JUNIPER.import 
3. Look for Juniper-EX-Series-Driver definition, make change as below:
   From
   

   GA_CompoundDriver::Containment-Juniper-EX-Series-Driver { 
       drivers = { 
           {"Containment-Create-Interface-Driver", 10}, 
           {"Containment-IfMIB-Stack-Driver", 15}, 
           {"Juniper-Port-Creation-Driver", 20}, 
           {"DOT3-Duplex-Driver",25}, 
           {"Containment-IfTable-Driver", 30}, 
           {"Juniper-Card-Slot-Driver", 40} 
       } 
       waitForCompletion = TRUE 
   } 

   To: 
   

   GA_CompoundDriver::Containment-Juniper-EX-Series-Driver { 
       drivers = { 
           {"Containment-Create-Interface-Driver", 10},       
           {"Containment-Create-Interface-Ext-Driver", 20},
           {"Containment-IfMIB-Stack-Driver", 30}, 
           {"Juniper-Port-Creation-Driver", 40}, 
           {"DOT3-Duplex-Driver", 50},
           {"Containment-IfTable-Driver", 55}, 
           {"Juniper-Card-Slot-Driver", 60} 
       } 
       waitForCompletion = TRUE 
   }

4. Save the file.
5. Run ./sm_edit conf/discovery/tpmgr-param.conf, add the following entry to the file:

   IFTypePatternIFExt.1.3.6.1.4.1.2636.1.1.1.4.82.17 53|24|6

6. Restart the domain as changes are done in .import file for it to take effect.
7. Rediscovery device, required interfaces will be discovered and monitored.
