S-VLAN, C-VLAN, and Link MAs (Figure 52)
Customers and Provider (PB) share the same MD level space.
CFM processing scope within Customer/PB network is determined by the MD level selection.
The PB network normally only processes provider MD level OAM frames.
Customer C-VLAN OAM frames use customer MD level and are normally not processed by the
PB network.
S-VLAN CFM frames are only visible where S-TAGs are processed.
C-VLAN CFM frames are only visible where C-TAGs are processed.
Once the S-VLAN CFM frames are encapsulated by a BEB, they appear just like any data frame
within the PBBN. That is, they do not activate any CFM functions within the PBBN past the BEB.
