action parse

Mode: Configuration Mode


The action parse statement parses the user supplied value and pass it to the parsing function for verification and validation or manipulation during commit time. Usually when users use a value that is predefined in JUNOS, JUNOS does not allow redefining such values, and renamed the user-defined value to a different value, so that the characteristics of the predefined value is preserved.
