Question #: 11
Topic #: 2
You are troubleshooting connectivity issues in your InfiniBand network and need to test basic connectivity between nodes. Which command should you use to test basic connectivity between InfiniBand nodes?
The tool specifically designed for testingInfiniBand connectivityis **ibping**. It functions similarly to the traditional ping utility but is optimized forInfiniBand fabrics.
From theNVIDIA InfiniBand Diagnostic Utilities Documentation:
"ibping tests the connectivity of InfiniBand nodes by sending management datagrams (MADs) and verifying the response from the destination LID or GUID."
Tests basicnode-to-nodereachability
Supports testing viaLID, GUID, orport number
Helps verify subnet manager routing and fabric health
Incorrect Options:
pingandtracerouteare IP-based, not fabric-aware.
ibnetdiscovermaps topology but doesn't test live connectivity.
