TCP/IP Question(s)

Hi Folks,

 

We switched from a 620 to an 810 several months ago. We were/are running
TCP/IP. I want to get the 620 back on the wire to do some stuff but I don't
want to knock anything down on the 810 when I do this. And of course I set
this all up on the 620 five years ago and have no idea how I did it <BG>.
All of the TCP/IP stuff was migrated from the 620 to the 810. So I renamed
the Ethernet line and got rid of the Host Table Entries for the remote
controllers. And I changed the system name on the 620 to CHUCK

 

My question(s):

 

(1) on Work with TCP/IP Interfaces on the 810 I see:

 

      Internet         Subnet              Line      Line     

      Address          Mask             Description  Type     

                                                             

     127.0.0.1        255.0.0.0        *LOOPBACK    *NONE    

     172.16.10.11     255.255.255.0    ETHERNET01   *ELAN    

 

and on the 620:

 

      Internet         Subnet              Line      Line     

      Address          Mask             Description  Type     

                                                             

     127.0.0.2        255.0.0.0        *LOOPBACK    *NONE    

     172.16.10.81     255.255.255.0    ETHERNET02   *ELAN    

 

So that all appears to be redone for no interference, correct ?

 

On Work with TCP/IP Routes I see:

 

      Route            Subnet           Next             Preferred  

      Destination      Mask             Hop              Interface  

                                                                   

     *DFTROUTE        *NONE            172.16.10.1      *NONE      

     172.16.9.0       255.255.255.0    172.16.10.3      *NONE      

 

For both systems. 172.16.10.1 is a frame router and 172.16.10.3 is a
firewall.

 

On Work with TCP/IP Host Table Entries on the 810 I have:

 

     Internet         Host                   

Opt  Address          Name                   

                                             

     127.0.0.1        LOOPBACK               

                      LOCALHOST              

     And a bunch of entries for all of the remote sites...

 

      172.16.10.11     AS400.LEESUPPLY.NET

 

and on the 620:

 

      Internet         Host                   

      Address          Name                   

                                            

     127.0.0.1        LOOPBACK               

                      LOCALHOST              

172.16.10.81     AS400_2.LEESUPPLY.NET

 

And I'm not sure what else to check...

 

The LOOPBACK deals aren't different - do they need to be unique between
systems.

 

Comments welcome :-)
