Working with Administrator-defined Interface-based Exception Filters
You can add specific filtering rules at the interface level in addition to the built-in rules. Such rules
give you the capability of restricting access to a port, for specific reasons, such as a Denial of
Service (DoS) attack.
The filtering rules are set up in the same manner as filtering rules defined for a Policy — specify an
IP address, select a protocol if applicable, and then either allow or deny traffic to that address. For
more information, see “Filtering Rules” on page 5-3.
The rules defined for port exception filters are prepended to the normal set of restrictive exception
filters and have precedence over the system's normal protection enforcement (that is, they are
evaluated first).
To Define Interface Exception Filters:
1. From the top menu, click Wireless Controller. The Wireless Controller Configuration screen
is displayed.
2. In the left pane, click Topologies. The Topologies screen is displayed.
3. Select a topology to be configured. The Edit Topology window is displayed.
NOTICE
If defined improperly, user exception rules may seriously compromise the system’s normal security
enforcement rules. They may also disrupt the system's normal operation and even prevent system
functionality altogether. It is advised to only augment the exception-filtering mechanism if absolutely
necessary.
