ADD SUBNET Command
DEVICENAME device-name
is the name of the SLSA LIF that provides access to the Ethernet or token-ring
LAN, is the name of the ATM adapter, or is the name of the X25AM line that
provides access to the X.25 network. For information on how to choose a SLSA
device name, see the Hint on page 1-7. For information on how to choose the ATM
device name, see the Hint
on page 1-13.
When adding a SUBNET, the DEVICENAME for the SLSA SUBNET type does not
begin with a dollar ($) character. X25 SUBNETs still require the dollar ($) character
as do ATM SUBNETs.
IPADDRESS ip-address
specifies the Internet address of a host or the conventional loopback address,
which is 127.0.0.1. You can use the loopback address for testing. For more
information on IP addresses, refer to the Appendix B, NonStop TCP/IP Processes
and Protocols. This parameter is required.
SUNAME subdevice-name
defines the subdevice name. This attribute is valid only for type X.25 SUBNETs.
(Prior to the D30 RVU, the SUNAME had to be set using a TACL PARAM
command before a SUBNET could be added using SCF. Beginning with the D30
RVU, you cannot use PARAM commands in the TACL environment to specify
SUNAME for the NonStop TCP/IP subsystem—the subdevice name now is defined
by using this attribute.)
IRDP ON | OFF
enables (ON) or disables (OFF) the ICMP Router Discovery Protocol on the
SUBNET interface. IRDP is a mechanism for locating default routers and is
specified in RFC 1256. IRDP also must be enabled on any local LAN routers. If
redundant routers are configured with route hold-down times and advertisement
intervals of approximately 30 seconds, IRDP can be used to provide a “black hole”,
or dead gateway, detection mechanism. The NonStop TCP/IP subsystem
implements IRDP using IP broadcasts rather than IP multicasts.
ARPSERVER ON | OFF
enables (ON) or disables (OFF) the SUBNET to act as an ATMARP server. The
SUBNET must be of type ATM for this to function. The default is OFF.
Default: None.
Default: None.
Default: OFF.
