30.5 Do S
The Switch protects against Denial of Service (DoS) attacks, such as Scan attack and Ping of Death. The
goal of DoS attacks is not to steal information, but to disable a device or network on the Internet.
By default, the DoS feature is disabled. You need to enable it on the Switch and its ports. See
Table 155
on page 207
for the types of DoS attacks that the Switch prevents when you turn on this feature. You
cannot set the Switch to block a specific type of DoS attacks.
Note: DoS protection does not work on LACP-enabled ports.
