Service Creation Using Groups and Rules
“not mac=00:11:22:33:44:55” applies the rule so long as the MAC address of the unit is not the given address. In other words, it applies to every computer in the world but one.
The AND Operator
The “AND” operator is used to group two or more expressions of any type so that the rule applies if both the expression on the left of the “AND” and the expression on the right of the “AND” are true.
expression AND expression
For example:
The OR Operator
The “OR” operator is used to group two or more expressions so that a rule will apply if any of those expressions is true.
expression OR expression
For example:
“mac=00:11:22:33:44:55 OR ip=123.123.123.5” applies either if a device has the given MAC address or its IP address is 123.123.123.5.
