TCP/IP Profile
TCP/IP Direct Connect links require the IBM TCP/IP protocol stack running on your System/390. Your TCP/IP Profile will need to be modified to support the new link. The following is an example of the entries required to define a connection:
; CTC connection
DEVICE DEVCTC1 CTC a00 IOBUFFERSIZE 65535 LINK LINKCTC1 CTC 0 DEVCTC1
;
HOME
201.168.1.33 LINKCTC1
GATEWAY
;
;Direct Routes - Routes that are directly connected to my interfaces.
;Network First Hop Link Name Packet Size Subnet Mask Subnet Value
201.168.1 | = | LINKCTC1 | 4096 | 0.0.0.224 | 0.0.0.32 |
START DEVCTC1
Figure 5-23 shows a properly configured adapter for a mainframe with two logical partitions (0 and 1) and a server with TCP/IP Direct Connect configured for each partition.
Device pair (00,01) is used for LPAR 0 and device pair (02,03) is used for LPAR 1.
