HiSpeed WAN Comm. Installation and Service Guide
down
Marks an interface as inactive (down), which keeps the system from trying to transmit
messages through that interface. If possible, the ifconfigxd command also resets the
interface to disable reception of messages. Routes that use the interface, however, are
not automatically disabled.
mtu Value
Sets the maximum IP packet size for this system.
The Value variable can be any number from 60 through 4096, depending on the network
interface. The default value is 576.
detach
Removes an interface from the network interface list.
If the last interface is detached, the network interface driver code is unloaded.
netmask Mask
Specifies how much of the address to reserve for subdividing networks into subnetworks.
The Mask variable includes both the network part of the local address and the subnet
part, which is taken from the host field of the address. The mask can be specified as a
single hexadecimal number beginning with 0x, in standard Internet dotted decimal
notation, or beginning with a name or alias that is listed in the /etc/networks file.
The mask contains 1’s (ones) for the bit positions in the 32-bit address that are reserved
for the network and subnet parts, and 0s (zeros) for the bit positions that specify the host.
The mask should contain at least the standard network portion, and the subnet
segment should be contiguous with the network segment.
arp | –arp
Enables | Disables the ifconfigxd command to use the Address Resolution Protocol in
mapping between network-level addresses and link-level addresses. This flag is in effect
by default.
debug | –debug
Enables | Disables driver-dependent debug code.
Examples
1. To query the status of a HiSpeed WAN Comm. IP interface, enter the command in the
following format:
ifconfigxd xd0
In this example, the interface to be queried is xd0. The result of the command looks
similar to the following:
xd0: flags=60<NOTRAILERS,RUNNING>
inet 200.251.0.30 netmask 0xffffff00
2. To configure a HiSpeed WAN Comm. adapter interface, enter the command in the
following format:
ifconfigxd xd0 inet 200.251.0.30 up
3. To mark a HiSpeed WAN Comm. interface as down, enter the command in the following
format:
ifconfigxd xd0 inet down
