Q:
How does MA5200G configure VP transparent transmission service?
Alarm Information

Handling Process
A:
VP transparent transmission service is to transmit user's packet according to user's VPI information. PVC transparent transmission is to transmit according to user's VCI information. PVC transparent transmission can only transparent transmit ATM packet with AAL5 type. For FR service of early network of some banks and commercial enterprises, there may be ATM packet with transparent transmission of AAL1 type. It is realized with VP transparent transmission.
e.g. transparently transmit PVC as 8/32 under ATM1/0/5 interface to 8/59 under ATM 1/0/7through VP, detailed configuration is as follows:
interface Atm1/0/5.100                                                          
 undo shutdown                                                                  
 pvp 8                                                                          
 undo shutdown                                                                 
 #                                                                              
 bas                                                                            
 access-type layer2-relay-leased-line  
interface Atm1/0/7.100                                                          
 undo shutdown                                                                  
 pvp 8                                                                          
 undo shutdown                                                                 
 #                                                                              
 bas                                                                            
 access-type layer2-relay-leased-line  
 vp-relay inport Atm1/0/5 pvp 8 outport Atm1/0/7 pvp 8  
Attention points:
1. If it is required to make VP transparent transmission for PVC with VPI as eight, the PVC is made by VP transparent transmission under physical interface. PVC with VPI as eight cannot enable PPPOE service.
2. VP transparent transmission need configure at independent sub-interface or master interface. The interface cannot configure PVC of other service type.
3. When VP-RELAY configure transparent transmission service, imported port can only be master interface.
