3.5.2.6.4. Configure the MTU Value
Select the MTU value so that, the sum of the MTU value and Ethernet header length is aligned to 64.
Use the following command to set the MTU value:
$ ifconfig ifc_mcdma0 mtu <mtu value>
For example, the following command sets the MTU value as 1522. In this case, the sum of the MTU and the Ethernet header is 1536, which is aligned to 64.
$ifconfig ifc_mcdma0 mtu 1522
