Using The Dladm(1M) Command - Fujitsu PCI Gigabit Ethernet User Manual

-
The values of lp_10fdx_cap, lp_10hdx_cap, lp_100fdx_cap, lp_100hdx_cap, lp_1000fdx_cap, lp_1000hdx_cap, lp_pauseTX,
lp_pauseRX, and lp_autoneg_cap parameters are valid only when Auto-Negotiation is successfully established. These parameter
values are invalid when Auto-Negotiation is disabled or when Auto-Negotiation fails.
-
The parameter values set by the ndd(1M) command become invalid after rebooting the system.
-
Operation mode setting using the ndd(1M) command becomes effective for each physical interface. Therefore, the operation modes
of the VLAN interface and IPv4/IPv6 interface are changed at the same time.

3.5.4 Using the dladm(1M) command

By using the dladm(1M) command, the interface communication mode can be changed dynamically. Usually it is not necessary to change
the interface communication mode using the dladm(1M) command, but when you experience the following, please change the interface
communication mode using the dladm(1M) command.
This method can be used only by FUJITSU PCI GigabitEthernet 5.0 or later.

You changed a remote device from one which supports Auto-Negotiation to another which does not support Auto-Negotiation or vice
versa after system startup.
-
You want to change setting JumboFrame without rebooting.
