Ping Failure After Pppoa Configuration - HPE FlexNetwork MSR series Configuration Manual

Solution
Determine if this fault results from enabling OAM F5 Loopback cell transmission and retransmission
detection. When two routers are connected, the VPI/VCI values of the PVCs on the two routers must
be the same. If OAM F5 cell transmission and retransmission detection is enabled, and the VPI/VCI
values of the two directly connected nodes are not the same, the local PVC state cannot change to
up.

Ping failure after PPPoA configuration

Symptom
The PVC state is up, but after applications like PPPoA are configured, the remote node cannot be
pinged.
Solution
Make sure the remote node supports the same application as configured on the local node. For
example, if the local node uses PPPoA, the remote node must also use PPPoA.
If the remote node supports the same application configured on the local node, make sure the two
sides use the same type of AAL5 encapsulation protocol. For example, if one side uses aal5snap
and the other uses aal5mux, they cannot communicate. You can enable ATM packet debugging to
get some clues about possible causes of the ping failure.
