Command Usage
This switch provides more efficient throughput for large
sequential data transfers by supporting jumbo frames up to
9000 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.
Enabling jumbo frames will limit the maximum threshold for
broadcast storm control to 64 packets per second. (See the
“broadcast” command on page 3-100.)
