Description
Use this command to set the link operating mode for a network interface.
An operating mode is confirmed with a y or yes at the prompt. If the operating mode selected differs
from the current mode, the change is saved and the command exits.
Changing the link mode is not supported for all network interfaces or for all Ethernet network interfaces.
This command is only functional for the eth0 interface.
When selecting auto-negotiation, you can choose the specific link operating modes that are advertised to
the link partner. At least one common link operating mode must be advertised by both sides of the link.
When forcing the link operating mode, both sides of the link must be forced to the exact same mode. The
link does not work reliably if one side is set to auto-negotiate and the other side is set to forced mode.
Exercise care when using this command. Forcing the link to an operating mode not supported by the
network equipment to which it is attached might result in an inability to communicate with the system
through its Ethernet interface. It is recommended that this command only is used from the serial console
port. When used through an interface other than the serial console port, the command displays a warning
message and prompts the user to for verification before continuing. this warning is not displayed and the
user is not prompted when the command is used through the serial console port.
For dual-CP systems, the
the link operating mode on the active CP, you must issue this command on the active CP; to set the link
operating mode on the standby CP, you must issue this command on the standby CP. During failover, the
link operating mode is retained separately for each CP, because the physical links might be set to operate
in different modes.
NOTE: This command is not supported on the HP StorageWorks SAN Switch 4/32 switch and HP
StorageWorks SAN Director 2/128 and 4/256 directors that use a Broadcom PHY transceiver.
