Command Usage
• This switch provides more efficient throughput for large sequential data
transfers by supporting jumbo frames up to 10 KB for the Gigabit Ethernet
ports. 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.
• The current setting for jumbo frames can be displayed with the
show system
command (page 4-33).
