RE: Change Subnet Mask

If that is the interface you are connected through, and most shops will have
just the one, you vary it off, and no way to reconnect.

OK Pete I gotta ask. Why not do this from a PC connected with System i 
Access?  :-)

RE: Change Subnet Mask






You do not need to End TCP/IP or Vary off the Ethernet line, you just need
to Stop the Interface on CFGTCP option 1 before changing it (which is
CHGTCPIFC).  Once the Interface is Inactive, you put a 2 next to the
Interface Address, and enter your new Subnet Mask.  Then Start the 
interface
so it goes Active.  If this entire process take 10 seconds, then you are a
very slow typer :)

Just remember to do this from the Console, and not from a Client Access
session which is connected via TCP/IP on the interface you are shutting
down.

Subject: Change Subnet Mask

All,
    Our Net Admin just informed me that they are changing the subnet
mask.  From what I found, I know I have to end TCPIP, Vary off the line
description for the Ethernet card, use the cmd cfgtcp option 1 and
change the subnet mask value.  My question is, are there any other
gotchas that will prevent our system from communicating with the
network?   By the way - running a 270 w v5r4. 
Any information or point to any documentation will greatly be
appreciated 

Thank you
