SUMMARY

parser is braking on line "Power via MDI" and giving this error. textfsm.parser.TextFSMError: State Error raised. Rule Line: 55. Input Line: Power via MDI:

NOTE. I added another line above: ^(?:PoE|\s+Power)

And now it is not showing the error ^Power\s+via ^(?:PoE|\s+Power)

STEPS TO REPRODUCE

run it on any switch that has "Power via MDI" in the output

I think adding ^Power\s+via\s+\S+: similar to what you have done is the way to address. You will need to create a new test case for this as well if you want to put in a PR to fix the issue.

[RP-11]

Thx. I will try this out. It may take a bit until I can test it.

@RP-11 This should have been resolved by PR #919

Could you please test and report back so we know you're all set? Thank you!
