Configuring Jumbo Frame Support
An Ethernet interface may 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 Ethernet interface view, you can set the length of jumbo frames that are allowed to pass through the
Ethernet interface.
Follow these steps to configure jumbo frame support in interface view:
To do… Use the command… Remarks
Enter system view system-view —
Enter Ethernet interface view

Configure jumbo frame support jumboframe enable
[ value ]
Optional
By default, the device allows jumbo frames
within the specified length to pass through
all Layer 2 Ethernet interfaces.
If you set the value argument multiple times,
the latest configuration takes effect.
Setting the MDI Mode of an Ethernet Interface
NOTE:
Optical interfaces do not support the MDI mode setting.
