Setting the MTU on an interface

About the mtusize option

The mtusize option specifies the MTU to use for transmission between your host and the filer. You can use this option to set the jumbo frame size on any copper or fiber Gigabit Ethernet Contoller numbered II or higher.

Note
Jumbo frame support requires an interface that is operating at 1,000 Mbps.

You can also use the mediatype option to set the frame size on an FDDI interface when the network infrastructure does not support the default FDDI frame size. The MTU size does not include the media header or FCS (checksum).

Setting the MTU

To set the MTU for an interface, complete the following step.

Step	Action
1	Enter the following command: ifconfig interface mtusize size interface is the specific name of the interface to be changed. size is the size of MTU this interface should have. Example You specify an MTU size of 9000 for a Gigabit Ethernet interface e8 with the following command: ifconfig e8 mtusize 9000

Step

Action

Enter the following command:

ifconfig interface mtusize size

interface is the specific name of the interface to be changed.

size is the size of MTU this interface should have.

Example

You specify an MTU size of 9000 for a Gigabit Ethernet interface e8 with the following command:

ifconfig e8 mtusize 9000
