Syntax Description
interface
A name that identifies the type of interface. The type of interface affects the
applicability of other ipifconfig parameters.
The choices for interface are:
•
lnPci0 for Ethernet (the default on power-up)
•
atm0 for the ATM
•
sl0 for SLIP
ip_address
(Optional if already configured, mandatory if not) ip_address is a 32-bit IP address
in dotted decimal format. This parameter is mandatory when you first configure a
particular interface type (lnPci0, and so on). If you subsequently modify one or more
optional interface parameters, you can omit this IP address because the interface
name (interface, above) is sufficient to get the address.
netmask
(Optional) 32-bit net mask in dotted decimal format. Ideally, the PXM45 and any
routers associated with connected workstations exist in the same subnet. Specifically,
having the same subnet mask simplifies router configuration.
broadcast
(Optional) Broadcast address—applies to only Ethernet.
up | down
(Optional) Set the interface to be either up or down. Default is up. Setting it to down
turns off all IP packet communication. You should have a specific purpose for
downing the interface.
arp | noarp
(Optional) Enables or disables ARP for all connections on the interface. Enter the
keyword arp or noarp in its entirety. The default is enabled (arp). Note that disabling
ARP for Ethernet is a very unlikely choice.
If you disable ARP, the system subsequently prevents you from specifying ARP for
an individual SVC or PVC. If you need to disable ARP for a connection because a
particular interface or device does not support ARP, disable it though svcifconfig or
pvcifconfig.
svc | nosvc
(Optional) Specify whether SVC support is enabled on the interface. The choice
applies to all connections on the interface. The default is enabled (svc) and is the most
common application. Specific contexts may provide a reason to disable SVCs on the
interface.
