Synopsys

Arguments

rule

Expression against which DNS traffic is evaluated. Written in the default syntax.

Note:

* On the command line interface, if the expression includes blank spaces, the entire expression must be enclosed in double quotation marks.

* If the expression itself includes double quotation marks, you must escape the quotations by using the character.

* Alternatively, you can use single quotation marks to enclose the rule, in which case you do not have to escape the double quotation marks.

Maximum length of a string literal in the expression is 255 characters. A longer string can be split into smaller strings of up to 255 characters each, and the smaller strings concatenated with the + operator. For example, you can create a 500-character string as follows: '"<string of 255 characters>" + "<string of 245 characters>"'

Example: CLIENT.IP.SRC.IN_SUBENT(23.34.0.0/16)

action
