Continuous Resets And Clears Of The Virtual Circuit Established; Pvc Setup Request Rejected; Troubleshooting X.25 Pad; Failed To Ping Xot Svcs - HPE FlexNetwork MSR Series Comware 5 Layer 2 - Wan Access Configuration Manual

Continuous resets and clears of the virtual circuit established

Symptom
The virtual circuit can be set up, but is frequently reset or cleared during data transmission.
Analysis
The symptom might be caused by incorrect flow control parameter settings.
Solution
•
If the two sides are connected directly, verify the output window and input window of the local
end match the remote end.
•
If both sides are connected to the public packet network, consult the network administrator for
the correct flow control parameters.

PVC setup request rejected

Symptom
The PVC setup requests are always rejected.
Analysis
Check that the PVC range configured on the device is correct. X.25 refuses all PVC setup requests
beyond the configured PVC range.
Solution
To re-configure the PVC range:
•
Re-configure the PVC range with the x25 vc-range command.
•
Execute the shutdown command and then the undo shutdown command.

Troubleshooting X.25 PAD

Symptom
Failed to log in to a remote device after placing an X.25 PAD call to the remote device. The system
indicated the destination address was unreachable.
Solution
Check the following items:
•
The two ends of the X.25 PAD call are connected through an X.25 network and the physical
connection is normal. The serial interfaces used for connection are enabled with X.25
encapsulation and both of them support X.25 PAD. One end is DCE, and the other is DTE, both
using the same encapsulation type (IETF or nonstandard).
•
The destination X.121 address is correct. It must be the one assigned to the intended serial
interface at the server end.
•
X.25 switching is disabled, or a route is available to the server end when X.25 switching is
enabled. In the former case, the default route is used to route the call. In the second case, at
least one route must be configured for routing the call.
