EZB2420I
Logon exit refusing session

Explanation

XNX25IPI is refusing a logon session because:
  • For an MCH with LOGAPPL coded, the MCH is not defined by a LINK entry, or the MCH is not in a state where a logon is expected
  • The logon was not initiated by X.25 NPSI
  • A virtual circuit is not in a state where a logon is expected, possibly because a call request was unsuccessful.
The NPSI LU session logon is refused.

System action

Processing continues.

Operator response

Notify the system programmer if the message is issued frequently, and connections are failing.

System programmer response

Check the source of the logons; determine why the call request was unsuccessful.

Module

XNX25IPI

Procedure name

None.
