Configuring Support for Jumbo Frames
The 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.
Command Usage
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.
Command Attributes
Jumbo Packet Status – Configures support for jumbo frames.
(Default: Disabled)
Web – Click System, Jumbo Frames. Enable or disable support for jumbo
frames, and click Apply.
