Shalom,

That is done with the ndd utility.

To change it permanently you modify /etc/rc.config.d/nddconf

ndd -help

The "-help" option does not exist for ndd. It is simply -h. Also, the "mtu" variables one can tweak with ndd are for the behaviour etc of Path MTU discovery. A different if perhaps slightly related thing.

The MTU of actual interfaces is controlled via lanadmin commands.

The lo0 interface is not an actual interface. It is but a figment of the imagination of the TCP/IP stack. Lanadmin knows nothing about it.

Why do you want to change the MTU of the loopback interface?
