Usage Guidelines
• This command displays the number of attacks the switch has detected for several types of DoS attacks.
• Just because an attack is detected and reported, doesn’t necessarily mean an attack occurred. The
switch assumes a DoS attack is underway anytime the penalty threshold is exceeded. It is possible for
this threshold to be exceeded when no attack is in progress.
