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.

File Management
Managing Firmware
Firmware can be uploaded and downloaded to or from an FTP/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.
