Troubleshooting NIC Data Resolution (SRC CLI)


Description: The NIC does not resolve a request.


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. 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. Test the resolution process by using the test nic resolve command.

    See Configuring the NIC (SRC CLI).


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 (SRC CLI).

    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. 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 (SRC CLI).

  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
