SUMMARY

When subinterfaces are present, the subinterface is not included in the second group for the regex match for port information

STEPS TO REPRODUCE

EXPECTED RESULTS

results =
{'downtime': '',
'name': 'L3 Link',
'port': 'Te6/0/1',
'since': '',
'uptime': '9w4d'},
{'downtime': '',
'name': 'L3 Link VR',
'port': 'Te6/0/1.602',
'since': '',
'uptime': '9w4d'}

ACTUAL RESULTS

textfsm.parser.TextFSMError: State Error raised. Rule Line: 32. Input Line: Twe6/0/1.602   L3 Link VR 00:00:00       9w4d

[kuraijay]

would maybe using the below work better?

Value PORT (\S+)

Value PORT (\S+)

@kuraijay , @brianatlarge

\S+ would probably work out better in the long run

It is simpler than adding (\.[0-9]+)? to the end of that already long and complex regex. 😬
The below works, but I don't see a reason why \S+ couldn't be used instead.
Value PORT ([a-zA-Z]{2,3}[0-9]{1,2}\/[0-9]{1,2}(\/[0-9]{1,2})?(\.[0-9]+)?)

[mjbear]

The line formatting looks a little odd. I'd expect the "columns" to generally line up.
Example:
Twe5/0/1.602 L3 Link VR 00:00:00 9w4d
