These values are approximations and will begin limiting traffic when the traffic rate has surpassed the configured rate.
Protected Ports (Similar to Private VLANs)
Some applications require that no traffic be forwarded between ports on the same switch 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 switch. Protected ports have these features:
A protected port does not forward any traffic (unicast, multicast, or broadcast) to any other port that is also a protected port. Traffic cannot be forwarded between protected ports at Layer 2; all traffic passing between protected ports must be forwarded through a Layer 3 device.
Forwarding behavior between a protected port and a nonprotected port proceeds as usual.
You can also disable unknown multicasts and unicasts from being flooded to a protected port with the 搒witchport block unicast,?and 搒witchport block multicast?br>commands.
Port Blocking As mentioned earlier, you can block the flooding of unknown multicast requests and unicast requests with the following commands:
You can use the port security feature to restrict input to an interface by limiting and identifying MAC addresses of the stations allowed to access the port. When you assign
