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. MXL Switch
Range is from 594 to 12000. The default is 1554.
Defaults 1554

Version Description
9.9(0.0) Introduced on the FN IOM.
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 difference 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 configure 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.
port channels:
● All members must have the same link MTU value and the same IP MTU value.
● The port channel link MTU and IP MTU must be less than or equal to the link MTU and IP MTU values
configured on the channel members. For example, if the members have a link MTU of 2100 and an IP
MTU 2000, the port channel’s MTU values cannot be higher than 2100 for link MTU or 2000 bytes for
IP MTU.
VLANs:
● All members of a VLAN must have same IP MTU value.
● Members can have different Link MTU values. Tagged members must have a link MTU 4 bytes higher
than untagged members to account for the packet tag.
