Determining the Value for the CLAWADP Parameter

The number of CLAW device entries and associated CLAW control blocks are defined using the CLAWADP parameter of the SNAKEY macro. In choosing a CLAWADP value for a particular processor use the following:

CLAWADP = Number TCP/IP offload devices attached to a processor
Note:
The maximum value for CLAWADP is 84 because a maximum of 84 CDT entries can be saved on file for a particular processor.

For example, if you plan to attach 10 IBM 3172 Model 3 Interconnect Controllers to processor A, set CLAWADP for that processor to 10. When defining CLAWADP for a processor, do not set the value larger than the number of TCP/IP offload devices you will be attaching to that processor because the amount of storage needed for the CLAW control blocks increases significantly as the CLAWADP value is increased. See Storage Considerations for a discussion of storage.
