Topology Validation
The Topology Validation feature enables the Super Admin to verify that infrastructure is discovered correctly in Bridge. Bridge uses the onboarded NetQ server to compare the .dot or .json topology file from NVIDIA DSX AIR against the topology Bridge discovered. If any discrepancies exist, they are highlighted and can be downloaded for further examination.
Validation Checks
Bridge uses the onboarded NetQ server to run two validation checks. Overall Status reports Success only when both checks pass.
| Check | Description |
|---|---|
| LLDP Service | Verifies that LLDP (Link Layer Discovery Protocol) neighbor and link information discovered by Bridge matches the physical network. |
| Topology Blueprint | Verifies that the overall network topology discovered by Bridge matches the .dot or .json blueprint file uploaded from NVIDIA DSX AIR. This confirms that nodes, links, and connections in Bridge align with the simulation design. |
Prerequisites
Before performing topology validation, complete the following:
- Topology discovery — Physical infrastructure topology must be discovered in Bridge.
- NetQ server onboarding — A NetQ server must be onboarded in Bridge.
Validate Topology
- In the sidebar, click Infrastructure.
- Click Validate Topology.
- Upload the
.dotor.jsonfile used to create the NVIDIA DSX AIR simulation. - Click Validate Topology to compare it against the topology Bridge discovered.
Validation Outcome
Successful validation
If there are no network issues (for example, a link being down), the Topology Validation Summary dialog shows a successful outcome:
| Status | Result |
|---|---|
| Overall Status | Success |
| LLDP Service | Success |
| Topology Blueprint | Success |
Use the Summary as TREE or JSON format to review the validation results.
