• 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.
• After setting the jumbo frame size with the system mtu or system
mtu jumbo command (page 19-13), remember to use the jumbo
frame command to implement the new setting by enabling jumbo
frames.
• The current setting for jumbo frames can be displayed with the show
system command (page 19-7).
Example
Related Commands
show system mtu (19-14)
system mtu
This command sets the maximum transfer unit for traffic crossing the
switch. Use the no form to restore the default settings.
