SUMMARY

Parsing fails with textfsm.parser.TextFSMError: State Error raised. Rule Line: 34. Input Line: Unknown unicast blocked: disabled

It seems as if the template has no rule to match the "Unknown unicast blocked" and "Unknown multicast blocked" lines.

Earlier versions (I tried 1.2.1) work fine because they have a ^.+$$ entry at the end.

STEPS TO REPRODUCE

I am using Netmiko send_command() with the use_textfsm=True argument

    show_vlan_result = device.send_command('show interface switchport', use_textfsm=True)
    pprint.pprint(show_vlan_result)

EXPECTED RESULTS

    [{'access_vlan': '1',
      'interface': 'Fa0/1',
      'mode': 'static access',
      'native_vlan': '1',
      'switchport': 'Enabled',
      'switchport_monitor': '',
      'switchport_negotiation': 'On',
      'trunking_vlans': 'ALL',
      'voice_vlan': 'none'},
