4.2.5 Jumbo Frames
The Managed 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.
The Jumbo Frames configure screen in Figure 4-2-5 appears.

4.2.6.1 Copy Operation
You can upload/download firmware or configuration to or from a TFTP server. By saving runtime code to a file on a TFTP
server, that file can later be downloaded to the Managed Switch to restore operation.
You can also set the Managed 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.
