2 ifModeSet ifModeSet Sets the link operating mode for a network interface. SYNOPSIS ifmodeset ["interface"] ifmodeset interface -an [on | off] -speed [speed] -cap [full | half] ifmodeset --help DESCRIPTION NOTES OPERANDS 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. On the CP of a Brocade DCX or DCX-S4, this command supports eth0 and eth3 as interface parameters. On all other platforms, only eth0 is supported. When selecting autonegotiation, 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 same mode. The link does not work reliably if one side is set to autonegotiate 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 be used only from the serial console port. When used through an interface other than the serial console port, the command displays a warning message and prompts for verification before continuing. This warning is not displayed and you are not prompted when the command is used through the serial console port. For dual-CP systems, the ifModeSet command affects only the CP you are currently logged in to. To set 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. The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for details. This command has the following operands: "interface" Specify the name of the interface, optionally enclosed in double quotation marks. When issued on a Brocade DCX or a DCX-S4 CP, valid interfaces are eth0 and eth3. On all other platforms, only eth0 is supported. -an Configures auto negotiation. on | off Sets auto negotiation on or off. -speed speed Configures the speed. You can configure 1000, 100, or 10 as the speed. -capability Configures whether the capability of operation is full duplex or half duplex. 450 Fabric OS Command Reference 53-1002746-01
