Generate diff between candidate and running configuration. If the
|
||
|
|
remote host supports onbox diff capabilities ie. supports_onbox_diff in that case
|
||
|
|
candidate and running configurations are not required to be passed as argument.
|
||
|
|
In case if onbox diff capability is not supported candidate argument is mandatory
|
||
|
|
and running argument is optional.
|
||

|
:param candidate: The configuration which is expected to be present on remote host.
|
||
|
|
:param running: The base configuration which is used to generate diff.
|
||
|
|
:param diff_match: Instructs how to match the candidate configuration with current device configuration
|
||
|
|
Valid values are 'line', 'strict', 'exact', 'none'.
|
||
|
|
'line' - commands are matched line by line
|
||
|
|
'strict' - command lines are matched with respect to position
|
||
|
|
'exact' - command lines must be an equal match
|
||
|
|
'none' - will not compare the candidate configuration with the running configuration
|
||
|
|
:param diff_ignore_lines: Use this argument to specify one or more lines that should be
|
||
|
|
ignored during the diff. This is used for lines in the configuration
|
||
|
|
that are automatically updated by the system. This argument takes
|
||
|
|
a list of regular expressions or exact line matches.
|
||
|
|
:param path: The ordered set of parents that uniquely identify the section or hierarchy
|
||
|
|
the commands should be checked against. If the parents argument
|
||
|
|
is omitted, the commands are checked against the set of top
|
||
|
|
level or global commands.
|
||
|
|
:param diff_replace: Instructs on the way to perform the configuration on the device.
|
||
|
|
If the replace argument is set to I(line) then the modified lines are
|
||
|
|
pushed to the device in configuration mode. If the replace argument is
|
||
|
|
set to I(block) then the entire command block is pushed to the device in
|
||
|
|
configuration mode if any line is not correct.
