### Approach
#### What is the motivation for this PR?
Fix couldn't find interface error during add-topo:

#### How did you do it?

#### How did you verify/test it?
Run add-topo on physical testbed, not seeing interface errors anymore.

#### Any platform specific information?

#### Supported testbed topology if it's a new test case?

### Documentation
