• This 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.
• 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
packet-rate
command on page -156.)
• The current setting for jumbo frames can be displayed with the
show
system
command (page 4-79).
