By default, Ethernet port flow control is disabled.
Use the following configuration tasks to set the interval of performing statistics on
ports. The switch performs the statistics about the average speed during the
interval.
Perform the following configuration in Ethernet port view to set the interval of
performing statistics on ports.

During large throughput data switching, like file transmission, a card may
encounter jumbo frames larger than the standard Ethernet frame length. The
following command can be used to enable jumbo frames to pass a card or disable
them from passing a card.
Perform the following configuration in system view.
Table 75 Enabling/disabling jumbo frames' passing a card
Operation
Enable Jumbo frames to pass the card on a
specified slot, and set the maximum length of
Jumbo frames allowed to pass the card
