CONFIGURING SUPPORT FOR JUMBO FRAMES
Use the System > Capability page to configure support for layer 2 jumbo
frames. The switch provides more efficient throughput for large sequential
data transfers by supporting jumbo frames of up to 9216 bytes for Gigabit
and 10 Gigabit Ethernet ports or trunks. 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.

USAGE GUIDELINES
◆ 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.
◆ This command globally enables support for jumbo frames on all Gigabit
and 10 Gigabit ports and trunks. To set the MTU for a specific interface,
enable jumbo frames on this page, and then specify the required size of
the MTU on the port or trunk interface configuration page (see "Port
Configuration" on page 182 or "Trunk Configuration" on page 204).
