CLASS: Protocol 600-699
Chapter 12286
zx25d 652 Link ZLU <#>: VC RNR timeout on ZLU <#>.
Mux= <#>, Port= <#>, Subchannel= <#>.
Explanation: A remote DXE has returned an RNR flow control
protocol packet in response to a transmitted data
packet for a virtual circuit. An RNR packet mandates
that no further data packets on this VC be transmitted
to the DXE until an RR is received. The X.25
subsystem will allow this condition to exist for 120
seconds. If the remote DXE does not send an RR within
this time frame, this message is logged and the VC will
be reset.
Action: No action is necessary. This is an informational
message.
zx25d 653 Link ZLU <#>: MUX buffer shortage for VC ZLU <#>.
Explanation: This message should never occur during normal
operations. However, it generally indicates that the
X.25 link has not been configured correctly and/or the
application is not properly using X.25 subsystem with
regard to the MUX card buffers.
Action: No action is necessary. This is an informational
message.
zx25d 654 Link ZLU <#>: Unauthorized interrupt confirm on VC
ZLU <#>. Mux= <#>, Port= <#>, Subchannel= <#>.
Explanation: This message is logged when an Interrupt
Confirmation packet arrives for which no Interrupt
packet had been sent. This generally indicates a
protocol error in the remote DXE.
Action: No action is necessary. This is an informational
message.
