Troubleshooting NIC Data Resolution (SRC CLI)
Problem
Description: 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:
- Make sure that the heap size configured for NIC is adequate
and that the process is up:
user@host> show nic statistics processComponent 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
- Determine whether there are any NIC resolution errors
and whether NIC successfully completed any resolution requests:
user@host> show nic statistics hostComponent Statistics Component Name /hosts Number of Components Restart 0 Number of No Match Resolutions 0 Number of Resolution Errors 0 Number of Resolutions 0
- Test the resolution process by using the test nic resolve command.
If you are unsure whether NIC is resolving resolution requests, view data about those requests to see whether NIC is receiving data.
- 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.
- If NIC is not receiving data, determine which agent or agents are not receiving data by running the show nic data agent command.
- 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
