# GGSN GTP Info

From this dialog box, you can view the latest GGSN GTP information.

Note: This dialog box is available only if the value of cGtpGSNService is set to ggsn.

## Navigation

1. Right-click the Multi-processor WAN Application Module (MWAM) and then select Configure, or double-click the module.

2. Select MWAM module from the Category drop-down box.

3. With a device selected in the MWAM module dialog box, click Configure.

4. Select GGSN GTP Information from the Category drop-down box.

The following information is displayed:

> GPRS Service Type (cGtpGSNService)

> GTP Version (cGtpVersion)

> Max Retransmissions (cGtpN3Request)

> Receive Buffer Size (cGtpN3BufferSize)

> Max PDP Contexts (cGtpMaximumPdps)

> Availability of Notification (cGtpNotifEnable)

> Last Unreachable Address Type (cGtpLastNoRespToEchoGSNIpAddrTyp)

> Last Unreachable GSN IP (cGtpLastNoRespToEchoGSNIpAddr)

### GPRS Service Type (cGtpGSNService)

Indicates the type of GPRS service that is enabled on the device. Type can be:

Type | Description
undefined (0) | GPRS service functionality disabled
ggsn (1) | Device functions as a GGSN
sgsn (2) | Device functions as an SGSN
gtp-director (3) | Device functions as a GDM

### GTP Version (cGtpVersion)

GTP version supported by the GSN.

### Max Retransmissions (cGtpN3Request)

Maximum number of times a signaling request message is retransmitted, if no corresponding response message is received within the time specified in cGtpT3ResponseTimer.

### Receive Buffer Size (cGtpN3BufferSize)

Maximum size of the receive buffer for G-PDUs and signaling request messages. If a packet contains more data bytes than the receive buffer can contain, the packet is discarded.

### Max PDP Contexts (cGtpMaximumPdps)

Maximum number of PDP contexts that can be activated on the GSN.

### Availability of Notification (cGtpNotifEnable)

Indicates whether cGtpNotifications are sent when a notification is generated by the device.

Value | Description
true | Enables the device to send a notification
false | Prevents the device from sending a notification

### Last Unreachable Address Type (cGtpLastNoRespToEchoGSNIpAddrTyp)

Type of Internet address by which cGtpLastNoRespToEchoGSNIpAddr can be reached.

### Last Unreachable GSN IP (cGtpLastNoRespToEchoGSNIpAddr)

IP address of the last peer GSN device that did not reply to a GTP Echo Request message sent from the local GSN device.
