Troubleshooting NIC Data Resolution

Problem

The NIC does not resolve a request.

Solution

Troubleshooting NIC data resolution is a complex task that requires a good understanding of how NIC operates, how it resolves resolution requests, and how the NIC configuration scenario that you are using performs resolutions.

This topic provides high-level troubleshooting information. For further assistance troubleshooting NIC operation and NIC resolutions, contact the Juniper Technical Support Center.

Troubleshoot NIC operation:

  1. Make sure that the heap size configured for NIC is adequate and that the process is up:

    user@host> show nic statistics process 
    Component Statistics
Component Name process
Heap in use    456194 bytes (87%)
Heap limit     524288 bytes
Threads        42
Up time        747848 seconds since Wed Jan 31 19:35:57 EST 2007
    
                        
    
                     
    2. 
                     
  2. Determine whether there are any NIC resolution errors
                        and whether NIC successfully completed any resolution requests:

    user@host> show nic statistics host 
    
                           
    Component Statistics
Component Name                 /hosts
Number of Components Restart   0
Number of No Match Resolutions 0
Number of Resolution Errors    0
Number of Resolutions          0
    
                           
    
                        
    
                     
    3. 
                     
  3. Test the resolution process by using the test nic
                           resolve command.
                        
    See Configuring the NIC (SRC CLI).
                        
    
                     
    4. 
                  

                  
 

                  
If you are unsure whether NIC is resolving resolution requests,
                     view data about those requests to see whether NIC is receiving data.
                  

                  
    
                     
  1. Verify that NIC is receiving data by running the show
                           nic data resolver command.
                        
    See Viewing Data for NIC Resolvers .
                        
    
                        
    For each resolver, which is identified by a component
                           name such as /realms/login/C1, the output should show a value,
                           such as default@sys1 for the key Vr, and the NIC value for
                           that key such as the IOR that identifies an SAE.
                        
    
                     
    2. 
                     
  2. If NIC is not receiving data, determine which agent or
                        agents are not receiving data by running the show nic data agent command.
                        
    See Viewing Data for NIC Agents .
                        
    
                     
    3. 
                     
  3. Review your NIC configuration to make sure that NIC is
                        configured correctly by running the show command for the
                        NIC configuration scenario. For example:
                        
    
                              
    
                                 
    [edit shared nic scenario OnePop] 
    
                                 
    user@host# show
                                 
    
                                 
    
                              
    
                     
    4.
