1.1.8 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 ports, you can forward
frames with a size greater than the standard Ethernet frame size and yet still within the
specified parameter range.
You can set the jumbo frame length in Ethernet port view or port group view.
z If you set the jumbo frame length in Ethernet port view, the configuration takes
effect only on the current port.
z If you set the jumbo frame length in port group view, the configuration takes effect
on all ports in the port group.
Follow these steps to enable the forwarding of jumbo frames:

In Ethernet

Use either approach.
By default, the device
allows jumbo frames
with the specified
length to pass through
all the Layer 2/Layer 3
Ethernet ports.
 Note:
If you set the value argument for ports of a port group in Ethernet port view or
port-group view for multiple times, the latest configuration takes effect.
