xxx is a number in the range of 000 - 999, uniquely identifying the message

s is a letter indicating the severity level of the message:

pppmmxxxR Response message produced in response to a command

pppmmxxxF Fatal message signifying that a catastrophic error has occurred

pppmmxxxE Error message indicating that some kind of error has occurred and action should be taken to correct it

pppmmxxxW Warning message indicating that an action did not happen entirely correctly, but TCP could make adjustments or use defaults to correct the situation

pppmmxxxI Informational message about operations and actions in progress

pppmmxxxS Statistic message displaying metrics to be used for performance tuning, problem determination, and usage accounting

pppmmxxxD Debug message to help diagnose problems or provide further details about operations and actions

pppmmxxxT Trace messages recording specific events as they occur

Results of using the TPOIPBRO option (query IP broadcast value) when issuing a

TOPTION OPTCD=QUERY differ between Cisco IOS for S/390 release 1.0 and Cisco IOS for S/390 release 2.0. The result of the query on release 1.0 returns a value of 1 (allow broadcast), while the result on release 2.0 returns a value of zero (do not allow broadcast).

Returning the value of zero is correct since the default for Cisco IOS for S/390 release 2.0 is do not allow broadcast. Therefore, the SO_BROADCAST flag is not set. To set this flag to ON, you must run TOPTION with OPTCD=DECLARE and the TPOIPBRO option set to a value of 1 to override the default. After the flag is set, TOPTION OPTCD=QUERY will return a value of 1.
