IST887I

Explanation
 In response to a DISPLAY COS command for a PU
type 4 or PU type 5 (identified in a previous message), VTAM® attempted to display the class of service
(CoS) table for network netid.  For a PU type 4,
the COS table for netid was never defined on either
a BUILD or NETWORK definition statement for the PU.
 IF DISPLAY
COS,NETID=*NETWORK is entered, this message is issued for the model
network if no COSTAB keyword was coded on the model network statement.
 If COSTAB was coded on the model network statement, VTAM issues message IST862I.
 text can
be one of the following:  ISTSDCOS
ISTSDCOS, the default Class of Service table, may be used to identify
the virtual routes to be used in network netid.
DEFAULT ALGORITHM
The default Class of Service table, ISTSDCOS, was not loaded either
during VTAM initialization
or by a subsequent MODIFY TABLE command. The default algorithm may
be used to identify the virtual routes for use in network netid.

Service tables, and Class of Service resolution. See the z/OS Communications Server: SNA Resource Definition
