Statement introduced before Junos OS Release 7.4.
Specify a text string that must (or must not) appear in a message for the message to be logged to a destination.
If you configure both the match and match-strings statements for the same destination, Junos OS evaluates the match-strings condition first, and if the condition is satisfied, then the message is logged and the match condition is not evaluated. If the condition in the match-strings statement is not satisfied, then the system evaluates the regular expression in the match configuration statement.
The regular expressions must use the notation defined in POSIX Standard 1003.2 for extended (modern) UNIX regular expressions and must not contain a slash ( / ) or a percent sign ( % ).
