6.3.7 Configuring Support for Jumbo Frames
The ECN330-switch provides more efficient throughput for large sequential data
transfers by supporting jumbo frames of up to 9216 bytes for the Gigabit
Ethernet ports. 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.
