mtu
Set the link maximum transmission unit (MTU) (frame size) for an Ethernet interface.
Syntax
mtu value
To return to the default MTU value, use the no mtu command.
Parameters
value Enter a maximum frame size in bytes. The range is from 594 to 9252. The default is 1554.
Defaults 1554
Command Modes INTERFACE
Supported Modes Programmable-Mux (PMUX)

Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.4(0.0) Supported on the FN I/O Aggregator.
9.2(0.0) Introduced on the M I/O Aggregator.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
If the packet includes a Layer 2 header, the dierence between the link MTU and IP MTU (ip mtu command)
must be enough bytes to include the Layer 2 header.
• The IP MTU is adjusted automatically when you congure the Layer 2 MTU with the mtu command.
When you enter the no mtu command, The Dell Networking OS reduces the IP MTU value to 1536 bytes.
Link MTU and IP MTU considerations for port channels and VLANs are as follows.
