If you repeatedly use the speed and the speed auto commands to configure the transmission rate
on an interface, only the latest configuration takes effect.
Configuring Storm Suppression
You can use the storm suppression function to limit the size of a particular type of traffic (currently
broadcast, multicast and unknown unicast traffic) on a per-interface basis in Ethernet port view or port
group view.
In interface or port group view, you set the maximum broadcast, multicast or unknown unicast traffic
allowed to pass through an interface or each interface in a port group. When the broadcast, multicast, or
unknown unicast traffic on the interface exceeds the threshold, the system discards packets until the
traffic drops below the threshold.
The storm suppression ratio settings configured for an Ethernet port may become invalid if you enable
the storm constrain for the interface. For information about the storm constrain function, see
Configuring the Storm Constrain Function on an .
Follow these steps to set storm suppression ratios for one or multiple Ethernet ports:

on the current port only; if
configured in port group view,
this feature takes effect on all
ports in the port group.
Set the broadcast storm
suppression ratio broadcast-suppression { ratio |
pps max-pps | kbps max-bps }
Optional
By default, broadcast traffic is
not suppressed.
Set the multicast storm
suppression ratio multicast-suppression { ratio |
pps max-pps | kbps max-bps }
Optional
By default, multicast traffic is
not suppressed.
Set the unknown unicast
storm suppression ratio unicast-suppression { ratio | pps
max-pps | kbps max-bps }
Optional
By default, unknown unicast
traffic is not suppressed.
