IPADR - Assigning IP Addresses
Parameters PRCSR=prcsr
Description
Specifies the PRCSR statement that defines a DCP running the TCP~P Stack.
DCAEP=dcaname Description
Specifies the name of the DCATS, DCPTS, TRUNK, XEU, or NETADR statement that defines the DCA end point associated with this IPADR statement.
To define the relationship for TS/TN configurations, reference a DCATS, DCPTS, TRUNK, or XEU statement. For DNS configurations, reference a TRUNK, XEU, or NETADR statement. This parameter is required when either IPADDR parameter is flagged LOCAL.
If both IPADDRl and IPADDR2 are specified, you are configuring a DCA enpoint acrosss a TCP;1P network, and one of the addresses must be flagged LOCAL. In this case, the value for the DCAEP parameter can be the name of either a TRUNK or DCATS statement. A TRUNK or DCATS statement that is used as the value of the DCAEP parameter cannot also be referenced by a STATION or SAP statement.
IPADR - Assigning IP Addresses
IPADDRn=(adrl,adr2,adr3,adr4 [, [flagJ [,port ] ] ) Default
264 Range
for port (DCATS-te-DCATS pairing only)
1 to 65,535 for port
statement discussion for information on configuring trunks.
RIPNBR Identifies the IP address of an RIP neighbor node that uses routing information protocol. An RIP neighbor address cannot be fiagged LOCAL. This parameter is used only to define RIP neighbors on DCA networks .
. SERVER Identifies the address of the Domain Name System name server.
Port number is set to 265 to run ES-IS trunks over TCP-IP stack. In all other cases it is best to leave this parameter unspecified.

/IPADR - Assigning IP Addresses
DTEADR=dteaddress Description
The DTE address associated with the remote IP address specified on this statement.
It applies to the IPADDR that is not flagged LOCAL. This parameter is required for generic X.25 networks that do not support the IP-to-X.121 address translation algorithm used in the DDN. The format is a quoted string of up to 15 decimal digits.
This parameter should be used only when an associated SUBNET statement specifies TYPE=I PPDN.
NA={ nn I (sic,nn) I (sc,sic,nn) I (sd,sc,sic,nn) } Description
The DNS node address of a DCA end point across a TCP liP network. Use this parameter only for TCP-IP hosts that are not flagged LOCAL. This parameter is required for DNS subnetworks to enable the TCP~P Stack to discover other active
TCP~P nodes in the DNS subnetwork. The address format conforms to DNS addressing conventions and is identical to the NA parameter used on the NETADR statement.
NAMEl=name Description
Specifies a name for the host defined by the IPADDRI parameter. This name becomes an entry in the local host name directory. If you use this parameter, you do not need to use the NSM configuration statements.
NAME2=name Description
Specifies a name for the host defined by the IPADDR2 parameter. This name becomes an entry in the local host name directory. If you use this parameter, you do not need to use the NSM configuration statements.
IPADR - Assigning IP Addresses
Example 1
This example shows an IPADR statement defining a local host, that is, a host in the DCA network. The host could be an
as
1100 running DDN 1100, a DCPfunctioning as a TELNET terminal concentrator, or some other DCA system running TCP/IP software.
IPAI IPADR PRCSR=PRCl.DCAEP=HllOO.IPADDRl=(36.143.0.95.LOCAL) Example 2
This example defines a U Series or Personal Workstation2 host running Information Services (IS) software located across the TCP/IP network.
• The DCAEP parameter specifies a DCATS statement that uniquely identifies the remote host. This DCATS statement cannot be referenced by a STATION or SAP
statement.
• I PADDRI is flagged LOCAL and specifies the IP address of the local DCP.
• I PADDR2 specifies the IP address of the remote host.
IPA2 IPADR
Example 3
PRCSR=PRCl.DCAEP=REMOTEl.;
IPADDR1=(36.143.0.100.LOCAL). ; IPADDR2=(36.143.0.90)
This example defines a trunk connection to U Series or PW/IS End System (ES trunk).
• The OCAEP parameter specifies a TRUNK statement defining the DNS trunk to the U Series or PW end system. This TRUNK cannot be referenced by a
STATION or a SAP statement.
• I PADDR1 is flagged LOCAL and specifies the IP address of the DCP.
• I PADDR2 is the IP address for the U Series or PW host.
• The port number for an ES-IS trunk, which connects a DCP to an IS system, must be specified as 265 for both ends of the trunk.
IPA3 IPADR PRCSR=PRCl.DCAEP=TRUNKIS, ;
I PADDRI = (129.221 .2.91. LOCA L. 265) . ; IPADDR2=(129.221.2.112 .. 265)
Example 4
Example 4 defines a DNS or RTC trunk between the local DCP and a remote DCP across the TCPflP network. Each IPADR statement refers to the same TRUNK
statement, and each defines one end of the trunk.

Example 5 illustrates how to specify a DTE address for a TCPflP host connected to a generic X.25 PDN.
IPA4 IPADR PRCSR=PRCSRI. :
IPAODRl=(77.13.1,44).:
DTEADR='31108010009672' Example 6
Example 6 defines the
ncp
running TCP-IP Stack as a terminal concentrator (to support TELNET terminal access to TCPflP destinations). It specifies thefollowing:
• A DCPTS statement on the DCAEP parameter, which uniquely identifies the DCP
• One I PADDR parameter, flagged LOCAL, to assign an IP address to the DCPTS IPA5 IPADR PRCSR=PRCSR1,DCAEP=DCPTSl,IPADDRl=(36.143.0.100.LOCAL) Online Configuration Differences
