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.
this threshold to be exceeded when no attack is in progress.
