Command Usage
• When traffic exceeds the threshold specified for broadcast and multicast or
unknown unicast traffic, packets exceeding the threshold are dropped until the
rate falls back down beneath the threshold.
• Due to an ASIC chip limitation in this switch, the supported storm control
modes include:
- broadcast
- broadcast + multicast
- broadcast + multicast + unknown unicast
This means that when mulicast storm control is enabled, broadcast storm
control is also enabled (using the threshold value set by the multicast storm
control command). And when unknown unicast storm control is enabled, both
multicast and unknown unicast storm control are also enabled (using the
threshold value set by the unknown unicast storm control command).
Example
The following shows how to configure broadcast storm control at 500 kilobits per
second:

Command Usage
Statistics are only initialized for a power reset. This command sets the base
value for displayed statistics to zero for the current management session.
However, if you log out and back into the management interface, the statistics
displayed will show the absolute value accumulated since the last power reset.
