Configuring Support for Jumbo Frames
The switch provides more efficient throughput for large sequential data transfers by
supporting jumbo frames up to 9216 bytes. Compared to standard Ethernet frames
that run only up to 1.5 KB, using jumbo frames significantly reduces the per-packet
overhead required to process protocol encapsulation fields.
Command Usage
To use jumbo frames, both the source and destination end nodes (such as a
computer or server) must support this feature. Also, when the connection is
operating at full duplex, all switches in the network between the two end nodes must
be able to accept the extended frame size. And for half-duplex connections, all
devices in the collision domain would need to support jumbo frames.
Command Attributes
Jumbo Packet Status
– Configures support for jumbo frames. (Default: Disabled)
Web
– Click System, Jumbo Frames. Enable or disable support for jumbo frames,
and click Apply.

CLI
– This example enables jumbo frames globally for the switch.
Managing Firmware
You can upload/download firmware to or from a TFTP server, or copy files to and
from switch units in a stack. By saving runtime code to a file on a TFTP server, that
file can later be downloaded to the switch to restore operation. You can also set the
switch to use new firmware without overwriting the previous version. You must
specify the method of file transfer, along with the file type and file names as required.
Command Attributes
• File Transfer Method – The firmware copy operation includes these options:
- file to file
– Copies a file within the switch directory, assigning it a new name.
- file to tftp
– Copies a file from the switch to a TFTP server.
- tftp to file
– Copies a file from a TFTP server to the switch.
- file to unit
– Copies a file from this switch to another unit in the stack.
- unit to file
– Copies a file from another unit in the stack to this switch.
