The QSP feature is configured and displayed with six storm control
commands. All of the commands that begin with “STORM,” such as
STORM ACTION and STORM WINDOW, pertain to QSP.
See Table 241 for an explanation of the basic concepts involved with
storm protection.
This feature consists of the six commands listed in Table 242. You
configure the QSP commands in the Policy Map Class mode. However,
you display the QSP settings in the Privileged Exec mode.
