To do… Use the command… Remarks
Set the unknown unicast
storm suppression ratio
unicast-suppression
{
ratio | pps max-pps
}
Optional
By default, all unknown unicast traffic
is allowed to pass through an
interface, that is, unknown unicast
traffic is not suppressed.
If you set storm suppression ratios in Ethernet interface view or port group view repeatedly for an
Ethernet interface that belongs to a port group, only the latest settings take effect.
Setting the Interval for Collecting Ethernet Interface Statistics
Follow these steps to configure the interval for collecting interface statistics:
To do… Use the command… Remarks
Enter system view

Configure the interval
for collecting
interface statistics
flow-interval interval
Optional
The default interval for collecting
interface statistics is 300 seconds.
Enabling Forwarding of Jumbo Frames
Due to tremendous amount of traffic occurring on an Ethernet interface, it is likely that some frames
greater than the standard Ethernet frame size are received. Such frames (called jumbo frames) will be
dropped. With forwarding of jumbo frames enabled, the system does not drop all the jumbo frames.
Instead, it continues to process jumbo frames with a size greater than the standard Ethernet frame size
and yet within the specified parameter range.
In interface configuration mode (Ethernet interface view/port-group view), you can enable jumbo
frames that can pass through the Ethernet interface.

If you execute the command in Ethernet interface view, the configurations take effect only on the
current interface.

If you execute the command in port-group view, the configurations take effect on all ports in the
port group.
Follow these steps to enable the forwarding of jumbo frames:
