After two equal traffics that exceed the ATM bandwidth are sent to Router B, you can use the display
atm pvc-info interface atm 1/0/1 pvc command on Router B to view statistical results for each PVC
(you can make several tests and observe the average statistical value). You can see that the PVC with
higher priority receives more packets than that with lower priority. In other words, the PVC with the
higher priority takes preference in getting bandwidth and other PVCs (if there are many and with
different priority values), regardless of their priority values, are treated equally in terms of bandwidth
allocation.

Troubleshooting ATM

Link State Error in IPoA Application

Symptom
When IPoA is used, the link state is down.
Solution
Make sure that the optical fiber is plugged in correctly.
Make sure that the local IP address has been configured.
Make sure that the PVC is successful created and communication between cards is normal.

Link Report Error in PPPoA Application

Symptom
When PPPoA is used, the link does not report UP.
Solution
See Link State Error in IPoA

Ping Failure

Symptom
The physical layer of the interfaces and the line protocol are both UP, but when tested with the ping
command, the two ends are mutually unreachable.
Solution
If IPOA is used, make sure that the IP protocol address mapping is configured correctly. If the
interfaces of two routers are connected back-to-back, the local PVC mapped to the remote IP must
