Global Configuration
Command Usage
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.
T
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
switchport broadcast command on page 4-178.)
The current setting for jumbo frames can be displayed with the show system command (page 4-30).
