Commands > Configuration. You can preview a command before executing it, or schedule it to run at 
a later time. You may be prompted to enter your device access credentials while executing a command. 
Your permissions determine whether you can run these commands (see Permissions Required to Perform 
Tasks Using the Prime Network Clients). To find out if a device supports these commands, see the Cisco 
Prime Network 4.3.2 Supported Cisco VNEs. (You can also add support for new commands by

Working with GPRS Tunneling Protocol Prime (GTPP)
GPRS Tunneling Protocol Prime (GTPP) is used for communicating accounting messages to CGs. 
Enhanced Charging Service (ECS) supports different accounting and charging interfaces for prepaid and 
postpaid charging and record generation. GTPP accounting in ECS allows the collection of counters for 
different types of data traffic including the data in a GGSN CDR (G-CDR) that is sent to the CGF.
GTPP performs the following functions:
Transfers CDRs between the Charging Data Function (CDF) and CGF.
Redirects CDRs to another CGF.
Advertises to peers about its CDR transfer capability; for example, after a period of service down 
time.
Prevents duplicate CDRs that might arise during redundancy operations. The CDR duplication 
prevention function is carried out by marking potentially duplicated CDR packets, and delegating 
the final duplicate deletion task to a CGF or the billing domain, instead of handling the possible 
duplicates solely by GTPP messaging.
Prime Network provides support on gathering the GTPP accounting setup details that are configured in 
the mobile gateway for transferring the different types of CDRs from charging agent to a GTPP server 
or accounting server. 
GTPP is configured within the accounting context of an APN and is also used by GGSN, P-GW, and 
S-GW to transmit CDRs to CGF.
The following topics provide details on how to work with GTPP in the Vision client:
Viewing GTPP Properties, page 27-22
Viewing Additional Characteristics of a GTPP, page 27-23
GTPP Commands, page 27-28
Viewing GTPP Properties
the Vision client displays the GTPPs in a GTPP container under the Mobile node in the logical inventory. 
The icon used for representing GTPPs in the logical inventory is explained in NE Logical Inventory 
Icons, page A-7.
To view GTPP properties:
Step 1Right-click the required device in the Vision client and choose Inventory.
Step 2In the Logical Inventory window, choose Logical Inventory > Context> Mobile > GTPP Container.
The Vision client displays the list of GTPP groups configured under the container. You can view the 
individual GTPP group details from the table on the right pane or by choosing Logical Inventory > 
Context> Mobile > GTPP Container> GTPP Group.
Table 27-13 describes the details available for each GTPP group.
