Configuring an AS/400 for TCP/IP

From Support

1. Create an Ethernet Line Description

The command listed below can be used to create an AS/400 Ethernet Line Description. You will first need to identify the hardware resource name for the Ethernet card. This sample shows an AS/400 resource name of CMN03.

To identify your Ethernet line resource, use the GO HARDWARE command to go to the hardware menu and select option 1. (Work with communication resources)

CRTLINETH LIND(ETHLINE) RSRCNAME(CMN03) ONLINE(*YES) +                
VRYWAIT(*NOWAIT) MAXCTL(40) ADPTADR(420000000000) +          
EXCHID(05655555) ETHSTD(*ALL) LINESPEED(10M) +               
DUPLEX(*HALF) +                                              
SSAP((04 1496 *SNA)(12 1496 *NONSNA)(AA 1496 *NONSNA)(C8 +   
1496 *HPR)) THRESHOLD(*OFF) LINKSPEED(10M) COSTCNN(0) +      
COSTBYTE(0) SECURITY(*NONSECURE) PRPDLY(*LAN) +              
USRDFN1(128) USRDFN2(128) USRDFN3(128) AUTOCRTCTL(*YES) +    
AUTODLTCTL(1440) CMNRCYLMT(2 5) TEXT('Ethernet Port')        

2. Use the GO CMDTCP command to view all TCP/IP related commands.

3. Type CFGTCP to go to the Configure TCP/IP menu.

4. Take Opt 1. (Work with TCP/IP interfaces)

Type Opt 1 to Add a TCP/IP IP Address and connect it to the Ethernet card.

  Enter information similar to the following:

  Add TCP/IP Interface (ADDTCPIFC)

  X.25 maximum virtual circuits  .   64      
  X.25 DDN interface . . . . . . .   *NO        
  TRLAN bit sequencing . . . . . .   *MSB   
                                                                               
  After saving the entry, press F3 to return to the Configure TCP/IP menu.

5. Take Opt 10. Work with Host Table Entries

Type Opt 1 to Add a TCP/IP Host Table Entry Address and connect it to the specified AS/400 IP address.

  Enter information similar to the following:

  Add TCP/IP Host Table Entry (ADDTCPHTE)

  Host names:                                                                    
  Name . . . . . . . . . . . . .   S1012477
  Text 'description' . . . . . . .   Host Name for RJS AS/400 System
 

After saving the entry, press F3 to return to the Configure TCP/IP menu.

6. Take Opt 12. Change local domain and host names

  Enter information similar to the following:

  Change Local Domain and Host Names                       

Type choices, press Enter.

 Local domain name . . .   RJSSOFT.NET
 Local host name . . . .   S1012477

Congratulations, basic TCP/IP Configuration should now be complete.

7. Use the STRTCP STRSVR(*YES) command to start TCP/IP support.
