CISCO-GGSN-MIB: View SNMP OID List / Download MIB

This MIB module manages the Gateway GPRS Support Node (GGSN) devices. A GGSN device provides interworking with external packet-data network of a particular GPRS service provider. It provides a combination of IP routing and GPRS specific functionality to support mobile users. GTP version1 is introduced in UMTS release 99 and Cisco GGSN will support both GTP version 1 (GTP v1) and version zero (GTP v0) simultaneously. GTP v1 supports multiple PDP contexts sharing one IP address. TFTs are introduced to achieve this. Each TFT is associated with a PDP context and there may exist one PDP context without TFT amongst all PDP contexts sharing the same IP address. Each TFT has one to eight packet filters each assigned with a precedence index. These packet filters are evaluated one at a time against the packet header information in sequence of their precedence index. A match is claimed if all the filters are matched and the PDP context that the TFT belongs to will be selected, else the checks are performed against the filters of another PDP context. If the packet header doesn't contain any TFT packet filter information, then the PDP context without the TFT is selected for further processing. Note on notifications: When an alarm occurs on the device, if the alarm's severity is higher than the severity filter threshold, a notification is generated by the device; and if cGgsnNotifEnabled is 'true', then the device's SNMP-engine configuration will be searched to determine where to send the notification.

Whenever a connection outage is detected (by keepalive mechanism etc.) by GGSN to the PDF server. The GGSN waits for the interval configured in this object. Once this timer is expired, another attempt is made for connection establishment.

This is the number of attempts for connection establishment after the timeout value set in cGgsnPdfReconnectTimeOut. After the configured number of retries, all the COPS sessions (and associated PDP contexts) are cleared. The value '65535' which is default, will be infinite retries.

This objects defines the handling of the PDP context in the connection loss scenario. When this object is set to true, then on connection loss, the PDP delete will be initiated.

This object is used to create a new row or delete an existing row in this table. To create a row, set this object to 'createAndGo(4)'. To delete a row, set this object to 'destroy(6)'.

GGSN memory overload protection is a mechanism to prevent GGSN from completely running out of memory when GGSN is running near its capacity or in some failure scenarios like CG down. A protection mechanism was put into place where charging triggers would be ignored, PDP create would be rejected, PDP update request will delete PDP, once the available memory on the GGSN drops below a configured threshold. Charging triggers occurs due to certain criteria's like volume limit, time limit. When one of the conditions is met , the CDR's are closed and will be updated to the charging gateway.

GGSN supports this GPRS service mode for maintenance purposes. Two modes are supported in GGSN, operational and maintenance mode. 'inService' mode represents nominal operation, and there will be no change in the way the GGSN operates. 'maintenance' mode imposes restrictions, such as some of the configurations allowed by the GGSN, and no new PDPs will be accepted. 'maintenance' mode can be useful to make some changes to the configuration of the GGSN without affecting the existing PDPs. 'maintenance' mode gloablly applies to the GGSN, which means the whole box will be put in maintenance mode. There also exists APN level maintenance mode, which is defined in CISCO-GPRS_ACC-PT-MIB, and charging maintenance mode which is defined in CISCO-GPRS-CHARGING-MIB, which is out of scope of this MIB. Internally GGSN maintains three states (inService, maintenance and outOfService ), which can be viewed with cGgsnServiceModeStatus. The SNMP entity generates notification when switching modes. It uses the cGgsnInServiceNotif and cGgsnMaintenanceNotif for this purpose. Enumeration: 'maintenance': 2, 'inService': 1.

Mobile Country Code (MCC) and Mobile Network Code (MNC) together identify a GPRS PLMN of an operator. PLMN Ids other than home PLMNs are considered as foreign. There will be some situations where some foreign PLMNs has to be treated as trusted PLMNs. This table contains the list of PLMNs, there can be one home PLMN entry and multiple trusted PLMN entry.

Entry containing list of home PLMN Ids and the Trusted PLMN Ids.

The Mobile Country Code (MCC) is part of the PLMN Id.

The Mobile Network Code (MNC) is part of the PLMN Id.

This object is used to create a new row or delete an existing row in this table. To create a row, set this object to 'createAndGo'. To delete a row, set this object to 'destroy'. To modify a row, the row needs to be deleted and created fresh with new values.

This object specifies whether the PLMN is home or trusted. Only one PLMN entry can be home Enumeration: 'home': 1, 'trusted': 2.

This object specifies the PDP context timeout value. The PDP context will be terminated after this timer expiry. The value present in this will have meaning when the object cGgsnRadAttrSessTimeout is set to 'true' and if the attribute#27 not received from the AAA.

This object and cGgsnThruputIntervalTwo specifies the interval at which the data throughput needs to be collected per APN/SGSN. Once this object is set to some valid value, the data throughput collections gets started for per configured APN and per PATH created. The data throughput collection is updated periodically (each expiry of configured throughput interval) to the corresponding objects (cGgsnSgsnStatTable for per SGSN and cgprsAccPtThruputStatsTable for per APN). When this object is set to '0', the collection for this interval get stopped and the data related to this interval is deleted from the tables (cGgsnSgsnStatTable and cgprsAccPtThruputStatsTable). INCONSISTENT value SNMP error will happen when trying to set cGgsnThruputIntervalOne and cGgsnThruputIntervalTwo with same value expect '0'. Setting the same value to the same object will reset the value / collection status for that interval.

This object specifies the time interval TWO for collecting the throughput per APN/SGSN. This object is same as cGgsnThruputIntervalOne. It's just an option for a second throughput collection for a different throughput interval time. The value 0 means the timer TWO will be disabled. INCONSISTENT value SNMP error will happen when trying to set cGgsnThruputIntervalOne and cGgsnThruputIntervalTwo with same value expect '0'. Setting the same value to the same object will reset the value / collection status for that interval.

This object specifies the compliance level for the particular GGSN version present in cGgsnVersion. This object can be used to set back the compliance level to the previous GGSN version. When set to 'default', the compliance level for that GGSN version indicated by the object cGgsnVersion will be considered. Currently, when the cGgsnVersion is holding a value of 'release50', the compliance level can be set back to 'release40'. This object is deprecated as the standard GGSN 8.0 release deprecated this configuration. Enumeration: 'default': 0, 'release40': 1.

This object is used for backward compatibility due to to implementation of CR 311. CR 311: The SGSN shall not send a Create PDP Context Request for an already active context. If a new Create PDP Context Request is incoming on TEID 0 for an already active PDP context, this Create PDP Context Request must be considered related to a new session. The existing PDP context shall be torn down locally, and the associated PDP contexts deleted locally, before the new session is created. If a new Create PDP Context Request is incoming on a TEID which is different from 0 and this TEID is already allocated to one or more activated PDP contexts, and the NSAPI IE value in this message matches the NSAPI value of an active PDP context, the GGSN shall send back a Create PDP Context Response with a rejection cause code. It is implementation dependent deciding whether to teardown or keep the existing PDP context. 'false' - The changes due to CR 311 will be applicable. 'true' - The changes due to CR 311 will not be taken into account. This object has no meaning when the object cGgsnCompliance3GppGgsn holds a value of 'release40'. This object is deprecated as the standerd GGSN release 5.2 deprecated this configuration.

This object is used for enabling the session timeout feature on the global (router) level set using cGgsnSessionTimeout, APN level (cgprsAccPtAbsoluteSessionTimer, which is defined in CISCO-GPRS-ACC-PT-MIB and is outside the scope of this MIB) and also parse the RADIUS attribute #27 present in the access-accept request. 'true' - Session timeout is enabled. 'false' - Session timeout is disabled.

This object enables the feature which will allow the GGSN to route IP packets beyond MS. This works only if a static route is added in GGSN to the node beyond the MS. On enabling this feature, GGSN will route the packets in both process switch path and cef switch path. This is supported only for IP PDP type. This feature has some limitations: - This is not scalable, since the operator has to add static route to all the node beyond the MS. - Only works for MS having static address. - In case of GTPv1 the MS has to select TFT's so as to allow traffic flow in the downlink direction. - IP address assignment/Radius for the devices behind the MS needs to be done within the scope of that network; the GGSN will not provide this facility in anyway for the hosts behind the MS. - In case for MWAM and Cat6500/7600 environment, the static route should be added only on that particular GGSN on the MWAM from where the MS is reachable. 'true' - Routing beyond MS is enabled. 'false' - Routing beyond MS is disabled.

GTP SLB can operate in two modes-dispatched and directed. - 'dispatched' mode: It forwards the create request without changing the destination IP address (vserver address) and the create response comes from the same (vserver) address. - 'directed' mode: It changes the destination IP address to that of GGSN's VT and the create response comes from the GGSN VT. Enumeration: 'directed': 1, 'dispatched': 2.

This object is used to enable or disable the GGSN behavior of sending CAC failure notification to SLB, or session failure notification to SLB. If this object is set to cacFailure(1), then this object is required to enable the feature in the dispatched mode of operation of SLB. If this object is set to sessionDeletion(2), then GGSN will send delete notification message to SLB when the last PDP associated with a IMSI is deleted. This object is deprecated by cGgsnSlbNotifyCacFailure and cGgsnSlbNotifySessionDeletion. Enumeration: 'cacFailure': 1, 'sessionDeletion': 2.
