Working with the GPRS Tunneling Protocol User Plane (GTPU)
The GGSN communicates with SGSNs on a Public Land Mobile Network (PLMN) using the GPRS
Tunneling Protocol (GTP). The signaling or control aspect of this protocol is referred to as the GTP
Control Plane (GTPC) while the encapsulated user data traffic is referred to as the GTP User Plane
(GTPU). GTPU is used for transferring user data in separated tunnels for each PDP context.
You can configure various parameters for a GTPU using the configuration commands in Prime Network
Vision. You can view the configured parameters for a GTPU in the logical inventory.
The following topics explain how to work with GTPU in Prime Network Vision:
• Viewing GTPU Properties, page 25-11
• GTPU Commands, page 25-12
Viewing GTPU Properties
Prime Network Vision displays the GTPUs in a GTPU container under the Mobile node in the logical
inventory. The icon used for representing GTPUs in the logical inventory is explained in Logical
Inventory Icons, page A-7.
To view GTPU properties:
Step 1 Right-click the required device in Prime Network Vision and choose Inventory.
Step 2 In the logical inventory window, choose Logical Inventory > Context > Mobile > GTPU Container.
Prime Network Vision displays the list of GTPUs configured under the container. You can view the
individual GTPU details from the table on the right pane or by choosing Logical
Inventory >Context > Mobile > GTPU Container > GTPU.
Table 25-8 describes the details available for each GTPU.
