Figure 3-2. Sample Network
Basic Configuration. Suppose that in the sample network, the administra-
tor wanted to enable connection-rate filtering and configure the following
response to high connection-rate traffic on the switch:
■ Ports B1 - B3: Throttle traffic from the transmitting host(s).
■ Port B4: Respond with Notify-Only to identify the transmitting
host(s).
■ Ports B9, D1, and D2: Block traffic from the transmitting host(s).
Figure 3-3 illustrates the configuration steps and resulting startup-config file.
