User-Derived Role Example

The example rule shown in Figure 83 below sets a user role for clients whose host name (DHCP option 12) has a value of 6C6170746F70, which is the hexadecimal equivalent of the ASCII string laptop. The first two digits in the Value field are the hexadecimal value of 12 (which is 0C), followed by the specific signature to be matched.

NOTE: There are many online tools available for converting ASCII text to a hexadecimal string.
