Sense code 0861

COS name not valid: The class-of-service (COS) name, either specified by the ILU or generated by the SSCP of the SLU from the mode table is not in the "COS name to VR identifier list" table used by the SSCP of the PLU.

Bytes 2 and 3 following the sense code contain sense-code-specific information.

0000: COS name was generated by the SSCP.
VTAM® hint: If this sense code is displayed in message IST663I, and message IST264I follows, this might indicate that an incorrect COS table is referenced. The NetView® program also has a COS table, and if this error occurs, the NetView program library was concatenated in front of the VTAM library causing the wrong table selection. See the information about common subarea network problems in z/OS Communications Server: SNA Diagnosis Vol 1, Techniques and Procedures for more information about this problem.
0001: COS name was generated by the ILU.
0002: The COS name generated by the Type 2.1 CP local to, or the Type 2.1 NNCP server for, the ILU is not in the COS name definition table.
0003: The CDINIT request or response contains a session initiation control vector that has class-of-service (COS) name fields that have not been properly specified. A virtual route list could not be found associated with the COS name.
