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 3-92.)
