# interfaceNamesMatch

[Source](https://github.com/konoe-akitoshi/shumoku/blob/main/libs/@shumoku/core/src/observation/interface-name.ts#L143)

Whether two interface names denote the same physical port. Same canonical prefix with aligning numbers (score ≥ 0.5), OR — for cross-vocabulary cases like TTDB's speed-code \`hg\` vs Juniper \`et-\` where prefixes differ but the port number is identical — the full number sequence matches.

```
interfaceNamesMatch(a: string, b: string): boolean
```

| --- | --- | --- | --- |
