Ethernet Interface Configuration 59
n
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
Complete the following configuration tasks to configure the time interval for
collecting interface statistics. Use the display interface command to display the
interface statistics within the current interval.
Follow these steps to configure the interval for collecting Ethernet interface
statistics:
Enabling the Forwarding
of Jumbo Frames
Due to tremendous amount of traffic occurring in Ethernet, it is likely that some
frames might have a frame size greater than the standard Ethernet frame size. By
allowing such frames (called jumbo frames) to pass through Ethernet interfaces,
you can forward frames with a size greater than the standard Ethernet frame size
and yet still within the specified parameter range.
Follow the following steps to enable the forwarding of jumbo frames

If configured in Ethernet
interface view, this feature
takes effect on the current
interface only; if configured
in port group view, this
feature takes effect on all the
interfaces in the port group.

Optional
By default, all broadcast
traffic is allowed to pass
through an interface, that is,
broadcast traffic is not
suppressed.
