Specifications

The switch provides more efficient large sequential data transfers by supporting jumbo frames up to 9000 bytes. Compared to standard Ethernet frames that
run only up to 1500 bytes, 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 jumbo frames. In addition, 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. For half-duplex
connections, all devices in the collision domain must support jumbo frames.
To enable jumbo frame support on the switch, set the Jumbo Frame Support Status to Enabled.

Example

Console(config)#
Firmware Upgrade
From the Firmware page, you can configure the system to download a new version of the management software. The switch can contain two software code
files, one of which is set as the Start-Up file. This allows you to try a new version of the software without overwriting the previous version.

NOTICE: Enabling jumbo frames on the switch limits the maximum threshold for broadcast storm control to 64 packets per second.
