◆
This switch provides more efficient throughput for large sequential data
transfers by supporting jumbo frames on Gigabit Ethernet ports up to
10240 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.
◆
The current setting for jumbo frames can be displayed with the show
system command.
