Frame Size Commands
This section describes commands used to configure the Ethernet frame
size on the switch.
jumbo frame
This command enables support for jumbo frames for Gigabit Ethernet
ports. Use the no form to disable it.
Syntax
[no] jumbo frame
Default Setting
Disabled
Command Mode
Global Configuration
Command Usage
• This switch provides more efficient throughput for large sequential
data transfers by supporting jumbo frames on Gigabit Ethernet ports
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.
• The current setting for jumbo frames can be displayed with the show
system command (page 20-8).
