Configuring jumbo frame support

An Ethernet interface might receive some frames larger than the standard Ethernet frame size
(called "jumbo frames") during high-throughput data exchanges such as file transfers. Usually, an
Ethernet interface discards jumbo frames. With jumbo frame support enabled, the interface can
process frames larger than the standard Ethernet frame size yet within the specified range.
In system view, you can configure the switch to allow jumbo frames to pass through Ethernet
interfaces.

frame support.

Configuring a port group

Some interfaces on your switch might use the same set of settings. To configure these interfaces in
bulk rather than one by one, you can assign them to a port group.
You create port groups manually. All settings made for a port group apply to all the member ports of
the group.
Even though the settings are made on the port group, they are saved on each interface basis rather
than on a port group basis. You can only view the settings in the view of each interface by using the
display current-configuration or display this command.

If you use the group-member interface-type
interface-start-number to interface-type
interface-end-number command to add
multiple ports in batch to the specified port
group, make sure that the
interface-end-number argument must be
greater than the interface-start-number
argument.
