Type the maximum number of packets per second allowed on the port before it is blocked.
Note: The allowed range is 2 to 255 packets received per second.

host is blocked by using a MAC address filter. A blocked host is released automatically after
the MAC aging time expires.

Note: The allowed range is 2 to 100 ARP-request packets per second.
Note: The port-based threshold must be larger than the host-based threshold or the
