An entry in this table.

Indicates whether cGgsnNotification notification will
be sent when a notification is generated by the device.
- 'true',  it will enable the device to send a notification,
as well as logging the notification to the
cGgsnHistNotifTable.
- 'false', it will prevent the device from sending out a
notification, but it will still log the
notification into cGgsnHistNotifTable.

Indicates the least severity level of the cGgsnNotification
notifications to be generated by the device. Thus, notifications
are not generated for alarms with a severity level less urgent
than the value of this object. This object cannot be set to
cleared(1) or indeterminate(2).

The number of cGgsnNotification notifications that have
been generated since sysUpTime.

The number of alarms which are less severe than
cGgsnNotifLeastSeverLevel since sysUpTime, and thus,
for which no notification was generated.

The maximum number of entries to be retained in the
cGgsnHistNotifTable. When the table is full, the oldest
entries are removed to make space for new entries.

The value of cGgsnHistNotifIndex for the most recently
created entry in cGgsnHistNotifTable.

Detailed information concerning a particular notification
that previously generated from this device.

Specifies the default method by which the GGSN obtains
address leases for mobile user sessions.
- 'disable', which indicates that dynamic address
allocation is disabled.
- 'dhcp', which indicates that the DHCP server
will be used.
- 'radius', which indicates that the radius server
will be used.

This object specifies the time that the GGSN waits
before purging idle PDP contexts. A value '0' will
disable the purge timer.

Entry containing the start and end IP address in the address
range. An Entry with start IP > end IP is not allowed.
No new entry will be accepted if that would cause any IP
address(es) to be represented by more than one row in this
table.

An Entry contains the IP network prefix which is used to
combine the routes of PDP requests for the same network as
a single route on the GGSN.

This object specifies the AAA radius server group
that is used for authentication by all APN's on this GGSN.

This object specifies the AAA radius server group
that is used for accounting  by all APN's on this GGSN.

This object represents the virtual template interface used
by PPP Type PDP's.

This object represents the virtual template interface used
for PPP Regeneration by the APN's on which PPP Regeneration
is configured.
The value zero indicates that no interface is specified.

Entry containing the first and last IP address in the address
range. An Entry with first-IP > last-IP is not allowed. No
new entry will be accepted if that would cause any IP
address(es) to be represented by more than one row in this
table.

Entry containing the PDF servers details (name and
IP address) and also how the GGSN should communicate
with PDF, like timeout when there is no response,
number of retries.

An entry is created when the user configures the
group name and an IP address is set.

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.

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

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 used for backward compatibility due to
to implementation of CR 311 (Release 5).
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 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.

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.

For each COPS REQ sent to PDF, GGSN will start a request retry
timer with this value. If DEC is not received within the
timeout, the REQ is resent for cGgsnPdfReqRetries times.

This is the number of retries which has to be sent for the
COPS REQ being sent. If DEC is not received even after sending
the COPS REQ for configured number of retries, the PDP context
activation/modification (which had triggered this REQ) is
rejected.

This table contains the range of IP address used in the
GPRS PLMN. These IP addresses are used to avoid IP address
duplication in GPRS network. IP address duplication occurs
when a MS uses an IP address which is already used in the PLMN.
The IP addresses configured inside GPRS network should be in
these ranges and MS IP address should not be in this range.

This table contains the list of default aggregate routes
configured on the GGSN. GGSN uses a static host route to
forward user data packets for each PDP context received
from Gi interface to Gn interface. Using the aggregate
route (address range), the total number of static routes
implemented in the GGSN for PDP requests can be greatly
reduced.

This table contains the range of IP addresses that belong
to the PLMN nodes in a GPRS network. This range does not
include address of various entities like RADIUS, DHCP, DNS
servers, etc., which are not part of PLMN.

This table contains the details of PDF server that the GGSN
supports. The table elements describes their properties.
PDF's are the server's to which the client GGSN makes the
TCP connection using the COPS protocol over the Go
interface. GGSN can have connections with multiple
PDF's.

This table contains the entries of P-CSCF groups with the
addresses configured. One or more IP address can be
configured per group name. This group in turn will be mapped
to the APN.
P-CSCF is a network element providing session management
services. When the UE request the GGSN for P-CSCF
address through activate PDP Request, these addresses
will be returned to the UE in the order which they are
configured.

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.

This notification indicates the occurrence of a GGSN
related alarm. If and when additional useful information
is available for specific types of alarms, then that
information may be appended to the end of the
notification in additional varbinds.

A notification of this type is generated when GGSN
retains the memory and falls below threshold value
speficied by cGgsnMemoryThreshold.

A notification of this type is generated when PDF
connection comes UP.

A notification of this type is generated when PDF
connection goes DOWN.

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.
