nd(1M)

Synopsis

/etc/nd stop [ interface ]

/etc/nd restart [ interface ]

/etc/nd failover interface

/etc/nd failback interface

/etc/nd info action interface

Description

Configured network adapter drivers start automatically at system startup because /etc/nd is run by /etc/rc2.d/S15nd. Similarly, configured network adapter drivers stop automatically at system shutdown because /etc/nd is run by /etc/rc0.d/K85nd. See rc0(1M) and rc2(1M) for further information.

The nd command accepts the following arguments:

interface

The name of the driver instance on which the command will act. The interface name takes the form netX, where X is a number in the range 0 through N-1, and N is the number of adapters configured in your system. If the interface is not specified with start, stop, or restart, nd will start, stop, or restart all configured drivers.

start

Start a network driver.

stop

Stop a network driver.

restart

Restart a network driver after hardware failure.

failover

Switch the specified interface to a backup device.

failback

Switch the specified interface back to the primary device.

info action

Print information about a specified interface on the standard output. The action determines the type of information that is returned.

The actions that are recognized, the possible returned values and their meaning are shown in the following table:

Action	Returns	Information
is_primary	INFO interface Y	Primary interface
	INFO interface N	Backup interface
using_backup	INFO interface Y	Primary interface with backup
	INFO interface N	Primary interface without backup
	INFO interface	Backup interface
associated_driver	INFO interface driver	MDI driver associated with interface
current_driver	INFO interface driver	MDI driver in use by interface. For a backup interface or for a primary interface that has not failed over, this is the same as the associated driver
sibling_interface	INFO interface backup	Primary interface with backup
	INFO interface	Primary interface without backup
	INFO interface primary	Backup interface for primary
