# GGSN GTP Information

The GGSN GTP Information category of the Chassis Configuration dialog box displays the GGSN GTP information.

Note This dialog can be viewed if cGtpGSNService is set to 'ggsn'.

## Procedure

1. Right-click the device and then select Configure, or double-click the device.

2. Select GGSN GTP Information from the Category list.

The following information appears:

GPRS Service Type (cGtpGSNService)

GTP Version (cGtpVersion)

Max Retransmissions (cGtpN3Request)

Receive Buffer Size (cGtpN3BufferSize)

Bandwidth Resource (cGtpGSNTotalBandwidthResrc)

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.

### Bandwidth Resource (cGtpGSNTotalBandwidthResrc)

Total amount of bandwidth resource on the GSN. The total depends on various factors such as system throughput, memory size, and maximum number of PDP contexts supported. A portion of the total resources is allocated to a user at the PDP context activation time, based on the user's Qos class.

### 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.
