zx25d 434 Link <#>: Unexpected pkt (type=<#>) for ZLU <#> state <#>.
Call cleared or VC Reset has been issued.
Explanation: This message indicates that the DXE has transmitted
an X.25 level 3 protocol packet that is invalid for the
current state of the VC. For example, if the local DTE
sent a legal Call Request packet and the DCE
responded with a Data packet, the Data packet is
invalid for the DTE’s state. The only valid packets are a
Call Connected or Clear Indication packet. This
message indicates that the remote DXE is violating the
ITU-T X.25 protocol. A Clear or Reset Request will
automatically be sent as appropriate for the VC type
and current state. The packet type and state values are
as follows:
Action: No action is necessary. This is an informational
message. However, it may indicate a problem with the
remote DXE.
zx25d 435 Link <#>: VC enabled status received for term <#>, but no
ZLU is associated with it. Probable F/W failure.
Explanation: The X.25 Protocol driver received a VC enabled
unsolicited status message, however, there was no
associated VC ZLU for the indicated MUX terminal
number. This most likely means there is a defect in the
MUX firmware.
