Command Usage
• This switch provides more efficient throughput for large sequential data transfers by
supporting jumbo frames on Gigabit Ethernet ports or trunks up to 10240 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.
• 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.
• The current setting for jumbo frames can be displayed with the show system command.

Console(config)#jumbo frame
Console(config)#
File Management
Managing Firmware
Firmware can be uploaded and downloaded to or from an FTP/SFTP/TFTP server. By saving
runtime code to a file on an FTP/SFTP/TFTP server, that file can later be downloaded to the switch
to restore operation. The switch can also be set to use new firmware without overwriting the
previous version.
When downloading runtime code, the destination file name can be specified to replace the current
image, or the file can be first downloaded using a different name from the current runtime code
file, and then the new file set as the startup file.
Saving or Restoring Configuration Settings
Configuration settings can be uploaded and downloaded to and from an FTP/SFTP/TFTP server.
The configuration file can be later downloaded to restore switch settings.
The configuration file can be downloaded under a new file name and then set as the startup file, or
the current startup configuration file can be specified as the destination file to directly replace it.
Note that the file “Factory_Default_Config.cfg” can be copied to the FTP/SFTP/TFTP server, but
cannot be used as the destination on the switch.
