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.

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 4-149.)

The current setting for jumbo frames can be disabled with the show system command (page 4-82).

Example

Console(config)#jumbo frame
