Description (partial)

Symptom:
Due to the different encapsulation types included in notification messages, 3rd party remote end is unable to process the notification due to encapsulation mismatch. The PW does not come up.

Conditions:
The PW transport-mode must be configured as vlan.
The Notification and MAC withdrawal messages are impacted.
These messages are issued when the interface is shutdown and no shutdown for example.
IOS-XR does not enforce the VC type received in the Notification and MAC withdrawal messages.
3rd party Huawei brings down the PW if VC type differs in the Notification message.
