ID: This field determines the name by which this resource will be referred to elsewhere
on the CNA-8000. You should select a name that is meaningful and easily recognized. A
default name will automatically be assigned by CNA-8000.
Network Interface: This is the network interface associated with the subchannel. Each
XCA defined subchannel is dedicated to a network interface, specified in the gen. Up to
255 PUs can utilize a single XCA subchannel at a given time. Multiple XCA subchannels
(up to 8) can be assigned to a single network interface.
VTAM SAP: This defines the VTAM SAP that has been assigned to this subchannel in
the host gen. Traffic headed inbound will use this SAP as the destination SAP. Each
VTAM associated with a specific CU must have a different SAP associated with it. The
Gateway Circuit panel of the CNA-8000 maps network drops to the correct
subchannel/SAP.
Buffer Size: This value determines the maximum data (block size) that can be
transferred at a time over the subchannel. Normally this value should be left at the default
value.
Blocking Timeout (msec): This field determines how long the CNA-8000 assembles a
block of data before sending it inbound. If the maximum buffer size is reached prior to a
timeout occurring, the block of data will be queued for immediate inbound transfer.
Bytes per Trace Record: The value of this parameter determines the maximum size of
the associated Trace Record. Traces wrap when the maximum size record has been
reached with the oldest data deleted as new data gets added to the trace. The default value
for this option is 1024 bytes.
Button Definitions:
Update: The Update button causes the information on the panel to update the
configuration file. You must press the [Update] button before leaving the panel if you
want the changes to be made, otherwise the changes will be discarded.
Return: Selecting this button will take you back to the Update ESCON/FICON CUs
panel.
