DESCRIPTION
ifconfig assigns an address to a network interface and configures network inter-
face parameters. ifconfig must be used at boot time to define the network
address of each network interface present on a machine; it may also be used at a
later time to redefine a network interfaces address or other operating parame-
ters. When used without optional parameters, ifconfig displays the current
configuration for a network interface.
The
interface
parameter is the name of the network interface. The name is of the
form en for Ethernet interfaces, possibly followed by a letter, where
n
is 0 for on-
board network interfaces and the expansion slot number for network interfaces
plugged into expansion slots. If a card in an expansion slot has more than one
network interface, the network interface name will be followed by a letter, indi-
cating which of the network interfaces on that card it is. The network interface
name vh is used to specify IP virtual host addresses associated with the filer.
Only alias addresses (using the
alias
option) may be assigned to the vh interface.
The network interface name -a is special and it does not take any optional param-
eters. It displays the current configuration for all the network interfaces present.
The
address
is either a host name present in the host name data base /etc/
hosts or an Internet address expressed in the Internet standard dot notation.
OPTIONS
broadcast
address
Specifies the address to use to represent broadcasts to the network. The
default broadcast address is the address with a host part of all 1s.
down
Marks a network interface down. When a network interface is marked
down the system will not attempt to transmit messages through that net-
work interface. If possible, the network interface will be reset to disable
reception as well. This action does not automatically disable routes using the
network interface.
mediatype
type
Specifies the Ethernet media type used. Depending on the physical specifi-
cations of the Ethernet card the acceptable types are thick (10Base5 AUI),
thin (10Base2 BNC), tp (10Base-T RJ-45 twisted-pair), or tpfd (Full
