str

The IOSCfgLine text which matched. If there is no match, default is returned.

re_search_children(regex, recurse=False)

Use regex to search the text contained in the children of this IOSCfgLine. Parameters ———- regex : str

A string or python regular expression, which should be matched.

recursebool

Set True if you want to search all children (children, grand children, great grand children, etc…)

Returns

list

A list of matching IOSCfgLine objects which matched. If there is no match, an empty list() is returned.

re_sub(regex, replacergx, ignore_rgx=None)

Replace all strings matching linespec with replacestr in the IOSCfgLine object; however, if the IOSCfgLine text matches ignore_rgx, then the text is not replaced. Parameters ———- regex : str

A string or python regular expression, which should be matched.

replacergxstr

A string or python regular expression, which should replace the text matched by regex.

ignore_rgxstr

A string or python regular expression; the replacement is skipped if IOSCfgLine text matches ignore_rgx. ignore_rgx defaults to None, which means no lines matching regex are skipped.

Returns:
str

The new text after replacement

Examples

This example illustrates how you can use re_sub() to replace Serial1 with Serial0 in a configuration… .. code-block:: python

emphasize-lines:

15

>>> from ciscoconfparse import CiscoConfParse
>>> config = [
...     '!',
...     'interface Serial1/0',
...     ' ip address 1.1.1.1 255.255.255.252',
...     '!',
...     'interface Serial1/1',
...     ' ip address 1.1.1.5 255.255.255.252',
...     '!',
...     ]
>>> parse = CiscoConfParse(config)
>>>
>>> for obj in parse.find_objects('Serial'):
...     print("OLD {}".format(obj.text))
...     obj.re_sub(r'Serial1', r'Serial0')
...     print("  NEW {}".format(obj.text))
OLD interface Serial1/0
  NEW interface Serial0/0
OLD interface Serial1/1
  NEW interface Serial0/1
>>>
safe_escape_curly_braces(text)

Escape curly braces in strings since they could be misunderstood as f-string or string.format() delimiters…

If BaseCfgLine receives line with curly-braces, this method can escape the curly braces so they are not mis-interpreted as python string formatting delimiters.

set_comment_bool()

Set the .is_comment attribute for this object.

property subinterface_number

Return a string representing the card, slot, port for this interface or subinterface. If you call subinterface_number on GigabitEthernet2/25.100, you’ll get this python string: ‘2/25.100’. If you call interface_number on GigabitEthernet2/0/25 you’ll get this python string ‘2/0/25’. This method strips all subinterface information in the returned value.

Returns:
str

Warning

subinterface_number should silently fail (returning an empty python string) if the interface doesn’t parse correctly

Examples

This example illustrates use of the method.

>>> from ciscoconfparse import CiscoConfParse
>>> config = [
...     '!',
...     'interface FastEthernet1/0',
...     ' ip address 1.1.1.1 255.255.255.252',
...     '!',
...     'interface ATM2/0',
...     ' no ip address',
...     '!',
...     'interface ATM2/0.100 point-to-point',
...     ' ip address 1.1.1.5 255.255.255.252',
...     ' pvc 0/100',
...     '  vbr-nrt 704 704',
...     '!',
...     ]
>>> parse = CiscoConfParse(config, factory=True)
>>> obj = parse.find_objects('^interface\sFast')[0]
>>> obj.subinterface_number
'1/0'
>>> obj = parse.find_objects('^interface\sATM')[-1]
>>> obj.subinterface_number
'2/0.100'
>>>
property text

Get the self.text attribute

property trunk_vlans_allowed

Return a CiscoRange() with the list of allowed vlan numbers (as int). Return 0 if the port isn’t a switchport in trunk mode

property uncfgtext

Return a ‘best-effort’ Cisco IOS-style config to remove this configuration object.

This uncfgtext string should not be considered correct in all Cisco IOS command unconfigure cases.
