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.
To configure jumbo frame support:
Step Command Remarks
1.
Enter system
view.

2.
Configure jumbo
frame support.
jumboframe enable
By default, the switch allows jumbo frames within
2048 bytes to pass through Ethernet interfaces.
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.
To configure a manual port group:
Step Command

2.
Create a manual port
group and enter manual

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.
