Usage Guidelines
Use the show gprs gtp pdp-context command to display the currently active PDP contexts on the GGSN. You can display PDP contexts by tunnel ID, by IMSI, by access point, by PDP type, and by GPRS QoS precedence, or you can display all PDP contexts.
Interpreting the Effective Bandwidth
Example 2 provides sample output from the show gprs gtp pdp-context tid command, which includes the field called effective bandwidth (in bps). The effective bandwidth is determined according to the QoS class (high, normal, or best effort) for the PDP context; it does not represent the actual bandwidth in use by the PDP context. The potential number of supported PDP contexts for that class of QoS can then be calculated according to the total amount of bandwidth (GSN resource) available to the GGSN.
For example, the default bandwidth for a PDP context in the best effort QoS class is 10 bps. (You can configure this value using the gprs canonical-qos best-effort bandwidth-factor command.) The value 10 appears in the effective bandwidth field of the show gprs gtp pdp-context tid command for a PDP context in the best effort class.
To determine an estimate of the potential number of best effort PDP contexts that can be supported on the GGSN, you can divide the total bandwidth available on the GGSN by the effective bandwidth value. For example, the default bandwidth available on the GGSN is 1048576 bps. (The total GSN resource available is reported in the total gsn_resource field in the output of the show gprs gtp status command.) Therefore, you can divide 1048576 bps by 10 bps to yield support for approximately 104857 best effort PDP contexts.

Field

Description
|
get_pak_buffer_failure
|
Number of times the GGSN has failed to obtain a GTP packet.
|
ie_duplicated
|
Number of GTP messages received with a duplicated information element (IE).
|
ie_out_of_order
|
Number of GTP messages received with an IE out of order.
|
ie_unexpected
|
Number of GTP messages received with an IE that is not expected in the GTP message, but is defined in GTP. GTP messages with unexpected IEs are processed as if the IE was not present.
|
ie_unknown
|
Number of GTP messages received with an IE of an unknown type.
|
length_mismatch
|
Number of GTP messages rejected because the length field of the UDP and GTP headers did not match.
|
mandatory_ie_incorrect
|
Number of GTP messages received with an incorrect mandatory IE—for example, with an IE of incorrect length.
|
mandatory_ie_missing
|
Number of GTP messages received that are missing a mandatory IE.
|
msg_too_short
|
Number of GTP messages received that are too short to hold the GTP header for the supported GTP version.
|
no_resource
|
Number of times a resource was not available for transmitting GTP messages. For example, the router may be out of memory.
|
optional_ie_incorrect
|
Number of GTP messages received with an incorrect optional IE. This prevents the GGSN from processing the GTP message correctly.
|
optional_ie_invalid
|
Number of GTP messages received with an IE containing a value outside the defined range for that IE. GTP messages with invalid optional IEs are processed as if the IE were not present.
|
path_failure
|
Number of path failures on the GPRS Support Node (GSN).
|
pdp_activation_rejected
|
Number of times a request to activate a PDP context was rejected.
|
rcv_pdu_bytes
|
Number of bytes received in protocol data units (PDUs).
|
rcv_pdu_msg
|
Number of PDU messages received.
|
rcv_signaling_msg
|
Number of GTP signaling messages received.
|
snd_pdu_bytes
|
Number of PDU bytes sent.
|
snd_pdu_msg
|
Number of PDU messages sent.
|
snd_signalling_msg
|
Number of GTP signaling messages sent.
|
total_dropped
|
Number of GTP messages dropped.
|
unexpected_data_msg
|
Number of GTP PDUs received for nonexistent PDP contexts.
|
unexpected_sig_msg
|
Number of unexpected GTP signaling messages received—for example, a message received on the wrong end of the tunnel, or a response message received for a request that was not sent by the GGSN.
|
unknown_msg
|
Number of unknown GTP messages received.
|
version_not_support
|
Number of GTP messages received from devices running an unsupported version of the GTP.
|
total created_pdp
|
Total number of PDP contexts created since system startup (supports Special Mobile Group (SMG)-28 standards level and later).
|
total deleted_pdp
|
Total number of PDP contexts deleted since system startup (supports SMG-28 standards level and later).
|

show gprs gtp status
To display information about the current status of the GPRS Tunneling Protocol (GTP) on the GGSN (such as activated PDP contexts, throughput, and QoS statistics), use the show gprs gtp status privileged EXEC command.
show gprs gtp status
Syntax DescriptionDescription
This command has no arguments or keywords.
Defaults
No default behavior or values.
Command Modes
Privileged EXEC

Modification
|
12.1(1)GA
|
This command was introduced.
|
12.1(3)T
|
This command was integrated in Cisco IOS Release 12.1(3)T.
|
Usage Guidelines
Use the show gprs gtp status command to display information about the status of the GTP running on the GGSN.
The values displayed by the show gprs gtp status command show totals since the GGSN was started. Unlike the values displayed by the show gprs gtp statistics command, these values cannot be cleared.
Examples
The following example shows output from the show gprs gtp status command:
router# show gprs gtp status
gsn_used_bandwidth 0.0 total gsn_resource 1048576.0
activated_pdp 0 mean_throughput_premium 0.0
mean_throughput_normal 0.0 mean_throughput_besteffort 0.0
qos_high_pdp 0 qos_normal_pdp 0
qos_low_pdp 0 qos premium mean-throughput-deviation 0.100

|
show gprs gtp statistics
|
Displays the current GTP statistics for the GGSN.

subscription-required
To specify that a subscription is required to access a PDN through a particular access point, use the subscription-required access-point configuration command. To restore the default setting (no subscription is required), use the no form of the command.

Defaults
No subscription is required

|
Usage Guidelines
Use the subscription-required command to specify that a subscription is required for user access to PDNs through the current access point. The subscription must be set up by the service provider, and subscription information must be passed with the mobile user's PDP context requests.
Examples
The following example shows that access-point subscription is required:
access-point-name gprs.somewhere.com
use-interface
To configure the GGSN to use a specific interface for user access at a particular access point, use the use-interface access-point configuration command. To deactivate the use of a specific interface, use the no form of the command.
use-interface interface_name next-hop-address ip_address
no use-interface interface_name next-hop-address ip_address
Syntax Description
interface_name
|
Name of an interface on the router to be used by the specified access point.
|
ip_address
|
IP address of the gateway device for the virtual private network.
|
Defaults
No specific interface is used.

|
12.1(3)T
|
This command was integrated in Cisco IOS Release 12.1(3)T.
|
Usage Guidelines
Use the use-interface command to specify a specific router interface to be used with a specified access point. The interface_name argument specifies the name of the interface and the ip-address argument specifies the IP address of the Internet gateway device used for the virtual private network.
Examples
The following example specifies that access-point 1 will use the FastEthernet 4/0 interface on the router:
access-point-name gprs.anywhere.com
use-interface FastEthernet4/0 next-hop-address 4.0.0.2
