This feature allows you to configure protected port security on all modular platforms with installed 4-
or 9-port high-speed WAN interface card (HWIC) modules. Some applications require that no traffic be
forwarded between ports on the same device so that one neighbor does not see the traffic generated by
another neighbor. In such an environment, the use of protected ports ensures that there is no exchange
of unicast, broadcast, or multicast traffic between these ports on the device.
